How Long Does Cocaine Last?

Cocaine levels peak anywhere from 5-45 minutes after dosing (depending on mode of administration), but metabolites can last for days in your system. Personal tolerance, use, and exposure patterns also determine how long cocaine lasts. We examine more here.

ARTICLE SUMMARY: How long cocaine lasts depends upon mode of administration. We review factors that influence duration of effects. Plus, we’ll look at how getting high changes the brain.


How Cocaine Works

Cocaine produces its psychoactive and addictive effects primarily by acting on the brain’s limbic system, a set of interconnected regions that regulate pleasure and motivation. An initial, short-term effect is triggered by a buildup of the neurochemical dopamine. This gives rise to euphoria and a desire to take the drug again.

What are the effects of cocaine on the brain, how long does cocaine work, and is cocaine detectible in body fluids? Here, we review the way cocaine affects the brain and body, its duration and determinants of intensity. Your questions about finding help for cocaine addiction are invited at the end.

Brain Effects

Cocaine is a strong central nervous system stimulant. It unnaturally increases levels of dopamine, which helps regulates both pleasure and movement.


When cocaine is present, it causes disruption of the brain’s neurons and their activities. Cocaine prevents dopamine from being brought back to the cell that released it. This allows dopamine to build up in the nerve synapse, the space between nerve cells. In this way, dopamine released by cocaine acts as a destructive signal, manifesting malfunctions in internal brain communication with transmitters.

This is the main reason why you feel high on cocaine.

Cocaine acts on numerous regions in the brain, including:

  • The amygdala, a center for memory
  • The frontal cortex, a center for weighing options and restraint
  • The hippocampus, a center for memory
  • The nucleus accumbens (NAc), a pleasure center
  • The ventral tegmental area (VTA), another pleasure center

However, repeated use of cocaine can cause many short and long-term effects on the brain, each requiring medical attention. Furthermore, one of the most common mistakes that cocaine users make, especially relatively new ones, is to try to achieve the highest level of euphoria possible. However, fatalities from cocaine overdose can occur, even within previous drug dosing levels.

Body Effects

Cocaine triggers the brain to makes change in the body. Physiological effects of cocaine use include increased heart rate and blood pressure, increased body temperature, dilated pupils, increased light sensitivity, constriction of peripheral blood vessels, rapid speech, dyskinesia, nausea, and vomiting. Some of the short-term effects of cocaine may include:

  • Anger or irritability
  • Decreased appetite
  • Extreme sensitivity to touch, sound, and sight
  • Increased blood pressure
  • Increased heart rate

People who use cocaine often may also have more serious side effects and health problems, like:

  • Bowel decay if you swallow it
  • Convulsions and seizures
  • Headaches
  • Heart disease, heart attack, and stroke
  • HIV or hepatitis if you inject it
  • Loss of smell, nosebleeds, runny nose, and trouble swallowing
  • Lung damage
  • Mood problems
  • Sexual dysfunction

Cocaine users may also experience what’s called “co-morbidities”. These are other medical or health conditions that occur alongside use. The most commonly reported health problem is related to cardiac trouble. Increased heart rate, blood pressure, arrhythmia, and heart attacks can occur in people with otherwise healthy hearts who also use cocaine. But cocaine can also trigger problems in:

The Brain, such as strokes and seizures

The Gastrointestinal System, such as ulcers or perforation of the stomach or intestines

The Kidneys. Cocaine can cause sudden kidney failure due to rhabdomyolysis.  Cocaine also can damage the kidneys by increasing renal blood pressure.

Cocaine Duration Of Action

Cocaine duration of action depends upon mode of administration. Cocaine effects are different when administered by smoking, snorting, or IV injection. These methods of use are dangerous to your health, due to the rapid absorption of cocaine into your system.

The basic relationship is this: the faster the absorption, the faster the high from cocaine but the shorter the duration of effect.

Here are some key points to consider:

  • Bioavailability reaches up to 70% after smoking cocaine, meaning that the brain is affected almost instantly.
  • Injecting cocaine produces effects within 30 seconds
  • After oral administration, general effects last for up to 2 hours.
  • Post-effects of cocaine may continue for days, especially with binge use.
  • Despite the fact that main cocaine metabolites, such as ecgonine methyl ester, are centrally inactive, cocaine manages to be bound in plasma up to 90%.



Additionally, the presence of cocaine in the bloodstream cannot directly be associated with a certain level of intoxication without additional information. The level of individual tolerance to cocaine and minor artificial changes to cocaine during storage also act their role in the length and strength of effects.

How Long Do Cocaine Effects Last?

Cocaine effects last for different amounts of time, based on how to you take it. Here is a list of cocaine doses taken through different routes. You’ll notice that cocaine levels reach plasma concentration peak levels at different time windows.

  • After intravenous injection, a single dose of 30mg reaches peak levels only after 5 minutes.
  • After snorting 100mg cocaine, peak levels are reached about 30 minutes later.
  • After smoking 50mg of cocaine base, peak levels are produced within 45 minutes.
  • After orally taking 140 mg/70 kg of cocaine, peak levels are reached after 1 hour.

Repeated doses of cocaine, also called binge use, can make a big difference on cocaine effects in the system. More on this below.

Cocaine Time In The Body

Cocaine has a very short half-life of only 0.2 -0.8 hours. However, that does not mean that evidence of cocaine is eliminated during this time. Benzoylecgonine, one of the main cocaine metabolites, can be present in urine for up to 4 days. This number is more than double for heavy chronic cocaine users, mainly following a binge use. Up to 2% of cocaine manages to leave the body unchanged through urine and about 70% of the initial amount of cocaine is recovered after 3 days.

Many people who are addicted to cocaine go through a phase called “withdrawal” when they try to quit using the drug or miss a dose. The length of time it will take cocaine to leave a person’s system depends on how frequent and heavily they used cocaine. Cocaine acute withdrawal symptoms commonly last for 1–10 weeks, and some symptoms like cravings, sleep problems, or mood disorder can last for months or years later.

Symptoms can include:

  • Anxiety
  • Chills
  • Cravings for the drug
  • Depression
  • Fatigue
  • Increased hunger
  • Muscle aches
  • Nerve pain
  • Nightmares
  • Trouble concentrating

Although you may be tempted to go “cold turkey” or use home remedies when you quit coke, withdrawal can be dangerous without medical supervision. If you attempt to detox at home…you can relapse, overdose, or trigger severe medical complications such as cardiac concerns or seizures. Or, the depression that happens during withdrawal can end in suicide if you’re not supervised.

A physician or doctor can monitor withdrawal to be sure you’re safe. Medical detox can also help relieve some of the unpleasant symptoms. Call us to talk about safely getting of cocaine. Our compassionate hotline operators can describe the treatment process…and let you know what to expect.


A cocaine overdose is more difficult to treat than withdrawal. Physical signs include:

  • Chest pain
  • Confusion, seizures, or tremors
  • Increased body temperature
  • Increased heart rate
  • Increased sweating
  • Nausea or vomiting
  • Trouble breathing

Watch for these mental signs of overdose, too:

  • Anxiety
  • Delirium
  • Hallucinations
  • Panic
  • Paranoia

Call 9-1-1 if you think it’s a coke overdose.

An overdose often leads to a stroke or heart attack. Seek emergency medical help if you think you’re going through overdose. An ER doctor will test for those conditions and try to treat them first. S/He may also use medication to treat other complications you have.

How Long Does A Cocaine High Last?

The intensity and duration of high effects of cocaine depend on the way it is administered.

Injection = Up to 15 minutes

Oral administration = Up to 2 hours

Smoking = 15-30 minutes

Snorting = 15-45 minutes

In order to prolong their high pleasurable effects, users often practice binge use, where doses of cocaine are repeatedly taken within a relatively short period of time. While the user is still high from the last dose, he decides to go for another one. However, practicing this dangerous technique can often lead to addiction, a chronic relapsing disease.

Addiction to cocaine is caused by drastic changes in the brain. Usually, you’re not aware of these changes. But you do experience strong cravings and constant compulsion for cocaine use. The brain changes are causing this! Then, you can start to neglect what’s going on around you. Most people tend to ignore the negative consequences to their own health…leading to desperate measures.

Cocaine High Effects

Cocaine high effects are almost nothing like any other drug, according to users. The high from cocaine usually consists of two phases. The early phase is mainly psychological and consists of euphoria, excitation, feelings of well-being, general arousal, increased sexual excitement, dizziness, self-absorbed, increased focus and alertness, mental clarity, increased talkativeness, motor restlessness, offsets fatigue, improved performance in some simple tasks, and loss of appetite.

Higher doses may exhibit a pattern of psychosis with confused and disoriented behavior, delusions, hallucinations, irritability, fear, paranoia, antisocial behavior, and aggressiveness.

The second phase of cocaine effects include psychological symptoms such as dysphoria, depression, agitation, nervousness, drug craving, general fatigue, or insomnia. Physiological symptoms of late phase cocaine use include itching/picking/scratching, normal heart rate, normal pupils.

Signs of a Cocaine Problem

Being around someone using coke can be scary. They are often volatile, aggressive, or even violent. So, if you suspect someone’s under the influence of cocaine, how can you be sure? Some of the signs someone’s using include:

  • Acting nervous
  • Animated or exaggerated mannerisms
  • Constant talking
  • Dilated pupils
  • Facial tics
  • Jerky, erratic movements
  • Rapid eye movement
  • Twitching

Any regular use of cocaine is a problem!

Cocaine is a highly addictive drug. It’s not a drug that will bring you anywhere good. You can end up financially desperate. Some people turn to activities that they never dreamt of in order to keep using. So, the following signs are red flags. Anyone who’s exhibiting the following signs needs immediate help.

  • Angry outbursts or mood swings
  • Borrowing money often, selling possessions, or stealing
  • Not caring about personal appearance or grooming
  • Obsessively picking at hair or skin
  • Strange sleeping patterns, staying up for days or even weeks at a time
  • Psychotic behavior, such as paranoia and hallucinations
  • Weight loss

  1. So just our of curiosity if the police encounter someone high on cocaine is there any reason they couldn’t monitor the person for say 2 hours until they come down? Seems like an awful lot of people are getting hurt and/or killed when the police attempt to “subdue” the person.

  2. It’s hard for me to compare my experience with blow to your scientific studies because in the mid 80’s – early 90’s I was a heavy user of the powder and never experienced any of those symptoms besides high heart rate. I mean like almost 1-2 oz a week straight china white
    Then just gave it up for over 20years ….
    Yesterday I happened to come across 1/2 a kik and started playin around and to my surprise it’s almost like I never stopped but now I’m not really needing it just as a casual bump now idk the stuff isn’t as pure as bacc in the days but it’s ok I guess

  3. Hi ive snorted cocaine for 2yrs mybe 2-3 times a wk i quit 22 days ago dont wanna relapse i dont have strong urges 2 use even find myself going longer in the day with out thinking about it.i feel like i beat my addiction did i?

  4. Good evening, there is something that I couldn’t find anywhere and it is the amount of cocaine (let’s assume pure) the liver can process by the our, and if after that the drug effect should disappear. I do not understand if when the high is gone it means that the drug has been digested or what, I would like a clearer explanation of the processing, time and efficiency, that the liver does.

  5. Hello so I did Cocaine about 4 days ago and i haven’t stopped feeling dizzy, decided to go to the doctor and be recommended pills for the dizziness…. will the pills affect me in anyway or is my system clear enough to start drinking the pills. It will mean alit if you answer thank you

  6. Thank you this interesting read. I was reading this while using a razor blade to thin out some cocaine that I found this morning while cleaning my local nightclub. I found about 5 grams in a blue carrier bag. I was going to flush it but then I thought, I wonder what its like as I have never done cocaine before. I’ve done speed (Amphetamine) before which they call ‘poor mans coke’
    Anyway, I’ve just snorted a gram, half up each nostril and I was wondering how long it takes to kick in but to be honest, I’m already feeling it now. Its a definite high and my throat feels a bit numb. Anyway, looks like its going to be a good weekend.

    I have a question for Ivana @ Addiction Blog regarding your comment where you say Cocaine stays in your hair for up to 90 days. What if your really careful when you snort it and make sure it all went up your nose? Also, if you shower every day, surly they cant be any traces left for that long. I can understand if you smoke it cos smoke gets in your hair but if you snort or IV then I’m sure you wont get any in your hair. Am I right?

    @Pam, Your brain is only high for a very short period of time and goes back to normal within hours. I’ve even heard people use opiates to bring you down from the high to level you out and make you normal so maybe the next time you take it, keep a couple boxes of Neurofen Plus in your purse,

    @sandra Regarding crack cocaine, I’m pretty sure you don’t have to worry about it being in your hair. From my experience, most people who use crack are extra careful not to lose a crumb so I doubt it will be in your hair luv.

    @michelle I bet your sex life is great because of it. Be warned, I heard blokes cant get it up or perform very well in the bedroom after they stop taking cocaine. As a side note, its also good for numbing sensitive body parts and creating amazing sensations, esp for women if you follow what I mean.

    Just wondering, can you tell mine has kicked in yet?

  7. My question isn’t about how long it last. Its about what to do or not do when you need to get the cocaine high away. Like get sober in other words.. So how can a human sober up from cocaine from snorting, injecting, oral use and smoking)

  8. Wow that’s crazy why would anyone want to go thru any of that. I would assume that would probably make you feel like shit the next day. ^^^^
    I’m only saying this because of how fun it sounds until the final stages of getting high from cocaine…..

  9. I used cocaine once and I had a fever the next day. Is that one of the side effects of cocaine and if so how long will the fever last

  10. I’ve been doing coke every weekend. Possibly more than a gram a week. All I want to know is, how long does coke stay in your system. How do I stop my addiction. Seems like I’m craving. Been holding my coke til the weekend. Then all of a sudden I got the urge to do coke. Every time I get my hands on it. Basically I’m about to spend a gram a night. Money is no issue, just looking for pointers, and help

  14. Just trying to figure out how long it last… last line was was maybe an hour ago and he’s trying to drive. He loves it and uses it if it’s available, but doesn’t buy it. Which means a very long time in between. But has a high tolerance. Because he used a lot as an under aged.

  15. I am in construction and have recently had operatives banned from site for testing positive for drugs. The levels were,1 person Cannabis 25ng/ml and 1 person Cocaine Benzoylecgonine 400ng/ml. I am trying to understand how long the actual effects or highs last ?. The lads said they ‘used’ over the weekend and these readings were taken on a Monday Morning. Basically whilst I appreciate they have taken the drug and they have the same showing in their blood or urine, has the ‘high’ left them so they are actually safe to work ?
    I’m thinking you can have the worst Alcohol hangover in the world and feel terrible for days yet pass a drink drive breathalyser test and be allowed to drive and work !!. I’m told you do not get the hangovers with cannabis / cocaine so do I have a case to argue that my workman should be allowed to work even though they have traces of drugs in their blood / urine because the high or main effects of the drug have passed ? I know that ultimately the decision on whether they are allowed to work is with the employer but I would just like some information to educate myself more.
    Any feedback would be appreciated

  16. Probably have accumulated 1.5g throughout day and night. Binge user in college. But last line was at 10. And now I’m super paranoid, 4 in morning, unlike any other times I’ve done it. Should I get help? Or do you think I’ll be okay also sneezing

  23. A friend is a heavy user. We had plans but he never showed up. After a day of not hearing from him he finally text me that he thought he was dying from a bad trip. I said I would pick him up but he didn’t know where he was. On the phone he was very confused. It’s the next day now, 2 days and I’m worried.

  26. Hi there,

    My husband did cocaine once after his been drinking a lot at a party. He is a sports man and doing drugs is not at all his thing, in his nature or culture.
    But it happened about 4 times now where he doesnt come home after drink with colleagues and admit to doing crack cocaine. The only time this happens is when his been drinking heavily. I have so many queations… Can this craving or brain wave happen only when his drinking. Should he quit drinking totally or go to a rehab? I am not sure what to make of this.

  27. I was positive for cocaine 21 days (3weeks) after a heavy binge use. I used multiple drugs take prescription drugs and liquid methadone daily. I also drink little water and I’m not very l what is the explanation for.

  28. The man I have been seeing for a few weeks has told me he loves me and I’m everything to him , will he be telling the truth as he only tells me when he has taken cocaine? ??

  29. I am 59 weigh 245 and did a half gram of cocaine on 1/30/2016 and have a drug test on 2/16/2016 will I pass be OK with staying away from it for 17 days

  30. Hi. I do coke 3 or 4 times a year. Last night I took 1 bump and 30 min later I was vomiting, nauseous, dizzy, headache, sweating. These symptoms have persisted for 22 hours now. It was strong, but is it possible to OD on just one bump? And is it possible that symptoms could last so long? I drank 3/4 bottle of champagne over a 7 hr period with not a lot of food. What might be the issue here? Thanks.

  31. But how long after a one night use will it take that individual to be at a ‘normal state’?? Clear thinking, positive attitude etc.

  32. I find that cocaine seems to have a different effect on me than it does for most people. I only use maybe 4 times a year, maybe 12 times total. I snort it in the binge method described and only do slightly less than my companions, who use more frequently. I notice that after I use I don’t feel any different at all, not for the rest of the night. The next morning, maybe 8-10 hours later I feel absolutely wonderful. Not high, but less depressed, awake and happy. This is unusual for me, as I have severe depression and hypersomnia. It’s especially a contrast from my companions who feel like crap in the morning. This good/ energetic feeling usually continues until the end of the next day, never any crash or comedown. This has happened every single time I’ve used. Going to bed sober I almost never wake up feeling “good”, it’s a struggle just to get out of bed. This kind of reaction doesn’t make any sense, is there any record of people feeling energized for 48 hours after snorting coke? I am female, slightly overweight, in my 20’s.

    1. Hi, M. Cocaine high time varies from person to person. It depends on dosage, frequency of use, the body itself, etc.

    1. Hi, Anthony. Cocaine can be detected up to 4 days in the urine. But, this number can be bigger for heavy cocaine users. Also, it all depends of dosage, frequency of use, person’s metabolism, etc.

  33. What is the best way to have someone tested for cocaine in there system. My boyfriend is an addict and wants to stop. He agreed to get tested as often as I want to have him tested to prove he hasn’t used it. I want to know the best way and how often is recommended to be able to see if he is staying clean.

    1. Hello Gabriel. It depends on so many factors. If you are a frequent user, the dilated pupils can be followed by constricted pupils. How long will they stay dilated depends on how cocaine is taken. If smoked (crack) pupils are dilated the fastest, if inhaled – a bit slower.

  34. I shared an 8 ball with my friend last night. Started at 11 pm and finished by 12 noon the next day. My heart is pounding about 96 bpm. I haven’t used this amount since February. Should I be worried?

    1. Hi Heather. If you feel the symptoms are getting worrying and more intense, please seek medical help. It may be nothing, but risking your life is not an option.

  35. How long does it take for the dopamine levels to level back out because i am not a cocaine abuser but tried it even having depression and anxiety in the recent past but had just gotten to a point where the depression and anxiety were gone but after the cocaine, i feel really angry and depressed.. help please. I will never touch that stuff again..

  36. How long after smoking cocaine does it reach your urine.For instances if i used cocaine /crack an then urined immediately after would it be in the urine already.

  37. Hello, I have not used cocaine in 3 years but just yesterday I decided to get some more. It was a mistake. However, I still have some left.. a lot left in fact. My question is.. well, I feel the cravings again. Sigh.. I’m seeing a psychologist and we have made so much progress and now I feel that I’m falling back into old habits. What other treatment options would be helpful for me to get on the right track and get off this stuff for good. Any and all advice will be much appreciated.

    1. Hi Jimmy. Counselors, psychiatrists or group therapy are some of the options. You have to work hard and be disciplined to stay sober. Cravings come and go, maybe you can work with addiction professionals to learn practical ways for resisting triggers and staying on track.

  38. Hi my husband has been doing cocaine since he was 15 he didn’t do it as much as he does now he won’t admit to me of what’s going on with him his nose bleeds when he blows his nose and his pupils are dilated . I’m very concerned about him he’s very aggressive at times he’s also very tired . How can i get him to admit it to me and for him to stop .

    1. Hi Michelle. It’s a lot for one person to have to do it all on you own. I believe you should seek professional help for your husband to quit use, get through withdrawal and then continue treatment that will prevent relapse and ensure long-term sobriety. I also advise you to seek counselor’s help for yourself and get some guidance on how to deal with the whole situation.

  39. I snorted cocaine on a Monday the 9th and I have to go and do a urine test Tuesday the 17the will the test still read positive r negative has it been long enough for the cocaine to be out of my system by now

  40. I smoked crack on the 2 second of January a few times and that was it now I had a urine test done by dyfes on the 14th of January in between that time I drank plenty of water,, large amount of apple juice my the urine was sent out to a lab im not a binge smoker do u think I will pass the test

  41. Hi Stuart. Try using a nasal spray, it might get rid of the irritants before they get bad or for a long-term solution, quit using cocaine.

  42. It is very possible to detect it if the hair hasn’t been cut. Especially if your son has used within the past 90 days. The average cost of this method is in the $100-$150 range.

  43. thank you for your reply to my question, is there any chance that you could give me a rough estimate as to how much it would cost to have a hair strand test to detect crack cocaine and alchohol please as my son has got to have one for the courts. without having the test done he cannot have any contact with his 4 year old daughter. we need to know roughly as he is not working at the moment & depending on the price me & his father might be able to pay for this, thank you very much

  44. Hi Sandra. Cocaine concentrations in hair are visible for at least 90 days after dosing. However, cocaine does not leave its marks at the root of the hair, but to specific areas. That means that it is there until the hair falls out or is cut off.

  45. can u answer a question for me please. if someone has used crack cocaine, only twice in the last 8months, will it show up in a hair drugs test? thank you

  46. Hello Pam. Cocaine can cause long term effects on the brain, especially impacting the ability to feel or experience pleasure. PAWS (protracted or post-acute withdrawal symptoms) from cocaine can last for months after last use. Are you seeing a psychologist or a psychiatrist for help in cocaine use recovery?

  47. Is it possible for your brain to become “normal” again after long term cocaine use and if so how long does it take the brain to recover?

I am ready to call
