Have you ever tripped out when smoking weed? Chances are you were experiencing an acute overdose of marijuana. Here, we will explain more about marijuana overdose, its symptoms and prognosis, as well as associated death rate. Your questions about how to avoid these risks or getting help for marijuana addiction are invited at the end.

How does unintentional marijuana overdose happen?

Marijuana is a plant called Cannabis Sativa. Marijuana leaves, seeds, stems, and roots are consumed by users for the purpose of feeling intoxicated or high. THC, or tetrahydrocannibinol, is one of the hundreds of compounds within marijuana, but is the principal chemical that produces major intoxicating effects; it is too much THC that causes overdose. Marijuana overdose occurs when users toke bigger doses more often, both during medicinal or recreational use.

Marijuana overdose – How much is too much?

Marijuana overdose complications are the result of the presence of THC and its concentration. THC can go up to 17% per dry weight of material and it is called sinsemilla. How much marijuana it takes to overdose can vary by person. Factors such as previous exposure to THC, tolerance, dependence, general health, height, weight, and age can all play a role in how much weed is safe for you. However, whether or not you’re mixing marijuana with other substances can also play a part in the severity of overdose (such as when you mix marijuana with alcohol).

In order to reach the wanted effect of high several “hits” are taken within minutes. Extremely high doses of marijuana, or doses combined with alcohol or other drugs can easily lead to intoxication or overdose. Especially when marijuana is used either as a starter drug or used on a daily basis. Likewise, when you smoke weed at the same time as using another illicit drug, you can provoke stronger effects of marijuana used on its own.

Immediate short-term effects of euphoria usually occur in the minutes directly following the administration of marijuana. A typical marijuana “joint” contains less than 10 mg of THC, and a user would have to smoke thousands of those in a short period of time to approach toxic levels. Still, marijuana with hashish, a concentrated oil containing the extract of the cannabis plant, can contain high concentrations of the psychoactive THC resins and can provoke overdose.

Marijuana overdose complications

Marijuana overdose does not cause death, but may cause mental impairment and distressing emotional states, such as paranoia, hallucinations, and disconnection from reality. Overdose can also cause fast or disturbed heart rhythm, sleepiness, clumsiness, dry mouth, dizziness, and low blood pressure. So far there have been no reported cases of lung cancer or emphysema attributed to marijuana overdose.

Overdose symptoms occur usually due to lack of awareness. Individuals who are suffering from a marijuana overdose may display the following symptoms:

  • dilated pupils
  • extreme feelings of paranoia
  • nausea and vomiting
  • problems breathing

Marijuana overdose prognosis

Marijuana overdose usually resolves within a few hours of acute intoxication. However, some of the effecs of marijuana overdose can be long lasting. People who experience hallucinations or delusions are also exposed to a higher risk of developing addiction, even in cases when marijuana is used medicinally. And marijuana overdose can lead to cases of long term depression, addiction, and even suicide.

Marijuana overdose death rate

There are cases with severe shutdown of blood circulation to the arms or legs in young people who smoked marijuana. In some cases, it was so severe that amputation was required. There is some debate as to whether smoking cigarettes, contaminated marijuana, or using other drugs may be part of this problem.

However, so far officially there are no overdose deaths directly from the use of marijuana. Still, marijuana is the most common companion to other illicit drugs with rough overdose symptoms and high death rate in USA.

  2. My wife smoked marijuana with 28% thc and is having a bad psychotic breakdown. She has been dillusional for 5 days now and has not bounced back yet, we are in a forgein country and have no insurance has anyone have any clue to resolve her mental state.

  3. I have taken(eat) marijuana by mixing it with potato and gatte and then fried this mixture its seems very tasty.Now I am suffering from lake of sensation and i also used to thinking different things which are leading me to disturb person . I am not regular user of marijuana. its about a week and i am not feeling as I was . how much time it will take to get me normal.

  4. Hey there charles,
    I know the test was like 4 months ago but normally you had a negative result. The thc stays in the bldy for around 2-3 week bur when using “sonne #7” it will be out in a week max 1,5
    Weeks its out of your boddy really quin uf you do the right things jut drink alot of water and use the sonne and you should be fine

  5. I learnt Marijuana impedes memory. Why is this fact not being emphasized? An impeded memory makes an impeded individual, family, community, society and Nation; taking away from us the 1st position and giving us the last – as individuals … and as a nation. That’s how much destruction this Drug is doing to us all. A ruin of our future as a nation. I frankly still see no good reason for its legalization.

  6. I have been smoking everyday about 2 months… Not heavily so to say actually what some would consider less than moderate. (about .25 to .5 grams) a day… I have a urine analysis scheduled in 11 days.. Using Sonne #7 and plan to dilute.. What are the chances of a negative test… Test to be administered is a 5 panel first check cup…

  7. I remember I gad hita gravity bong and before I he’d smoked three blunts and I guess I must if I’d because I keep seeing weird things and getting paranoid and vomited

  8. you NEVER hear about anyone overdosing from Cannabis Sativa. It’s just not heard of.

    PARENTS: If your children are smoking/have smoked pot, don’t worry about it too much. They’ll just become lazy and stupid, and probably eat a lot of your food. Otherwise, nothing to worry about.
    But yes, you can become ill after ingesting marijuana. It’s mainly meant to be smoked unless made into an oil. However, Marijuana is fine if ingested in food form, I.E. brownies.

  9. Hello my name is Matt and I’ve had one of these overdoses just recently. It’s been about 3 days since it happened. And I’m not high I’m just cloudy. How long will this take to go away? I am not a heavy user of the drug I use to do it about once or twice a week untill this happened. I believe it’s referred to as a half life. But I’m just curious on how long untill this cloudy feeling goes away?

  10. The problem (which drug treatment centers will never tell you) is the THC levels.

    You have strains like “Candy Jack” or “Mooonrocks” with 25-45% pure THC. The past 30 years has been “pot eugenics” with growers ONLY focusing on THC. It’s like moonshine vs. beer.

    In legal states growers are getting demand for high CBD and “balanced” weed that is akin to what you would find in nature 2000 years ago.

    THC is what produces the parania and only if it goes over the threshold which is diferent for each person.

    Marijuana was meant to be smoke where you get high little by little. What the growers have done today, making strains 20% + THC has normal is criminal. This has caused all the problems related to weed psychosis.

    If your going to buy some “dank” “cryp” or “chronic” or “hydro” in an illegal state that’s typically $20-$30 gram your simply getting a high THC strain. That’s all. Making it illegal has caused this because of volume issues (get high for less and less if you get caught since police don’t take THC content into consideration).

    Stop smoking high THC bud. You should be looking at high CBD or balanced lab tested buds.

  11. I did overdose on marijana oil so high TCH this was over a month ago and am left with Tinitus-never had till I had the overdose and a general lack of energy-maybe from not sleeping from the tinitus. worried that I have done permanent damage

  12. Hi I consumed edibles about three days ago and I feel like everything isn’t real still, my memory sucks, and I just feel like I’m not here at all. I just keep sleeping, and had a couple of panic attacks, PLEASE tell me when I will go back to normal, and it was my second time getting high

  13. Concerned mom.. Get rid of the vape pen. There are other reports of this happening. Please read the other sites containing research on marijuana. Try WebMD. Marijuana in and of itself is not a hallucinagen. It would have to be tainted by another substance to produce that effect.

  14. My son is 17 and is not a regular pot user.. APPARENTLY HE SMOKED 3 HITS OF THC OILS IN A VAPE PEN!! I found him twitching in his sleep& I immediately woke him up, not sure if he was dreaming or not and HE COULDN’T REALLY TALK HE COULDN’T WALK WITHOUT WOBBLING, HIS PUPILS ARE DILATED AND HE’S LAUGHING, THEN CRYING, ETC AND I AM FREAKING OUT!! ***PLEASE TELL ME HOW LONG HE WILL BE LIKE THIS***

    1. Hi Concerned Mom. It’s best to take him to the hospital where doctors can assess the severity of his symptoms and treat him accordingly.

  15. Please SItop with this unnecessary attack on Marijuana. What is wromg with you people? First it’s impossible to overdose on Marijuana and Second it’s a scare tatic used by those who think Marijuana is dangerous. If anyone is looking for answers on the effects of Cannabis stay far away from sites like this, educate yourself with all Cannabis has to offer. Finally, Cannabis is not a gateway drug. It’s man’s lack of ability control his/her body.

  16. Hey hello !
    I took 8 deep hits of strong marijuana for the second time in my life. After that I developed Depersonalization/Derealization disorder. I wonder if I got some kind of permanent brain damage because I do not have that tolerance to that 8 deep hits and it was really strong!!! So, it is consider as an overdose? Please could you help me with that

  17. At present it is estimated that marijuana’s LD-50 (required to overdose) is around 1:20,000 or 1:40,000. In layman terms this means that in order to induce death a marijuana smoker would have to consume 20,000 to 40,000 times as much marijuana as is contained in one marijuana cigarette. NIDA-supplied marijuana cigarettes weigh approximately .9 grams. A smoker would theoretically have to consume nearly 1,500 pounds of marijuana within about fifteen minutes to induce a lethal response.

    This is the medical fact about marijuana and overdosing.

  18. Hello Terry. THC, the main psychoactive chemical compound in marijuana, influences a specific class of receptors in the brain known as cannabinoid receptors. Those receptors, scientists say, affect the connection strength between neurons. THC increases the activity of a pathway that promotes protein synthesis in the brain and is correlated with long-term memory deficits. However, scientists uncover that even regular marijuana use doesn’t damage the brain permanently.

  19. My 16 year old daughter ingested marijuana this past weekend. She became quite ill; vomiting, fainting, hallucinating, etc. She slept it off and is feeling better but having trouble with her memory still 3 days later. How long might she expect to have this side effect?

    Thank you.
