Is marijuana addictive or not? Absolutely.  In fact, what makes marijuana addictive is euphoric effect.

While some people are tempted to drink and smoke weed at the same time, using more than one drug simultaneously can often lead to unwanted results.  When you’re feeling high, and reach out for another drug, you risk multiplying the regular effects of both drugs. So when you smoke weed and drink at the same time, the result is either a high level of intoxication, risky behavior and/or intensified stimulant or depressant effects.

More here on what to expect when mixing alcohol with marijuana use. And then, we invite your questions about smoking and drinking or even marijuana dependence symptoms at the end. We try to answer all legitimate questions personally and promptly.

Marijuana and alcohol effects

Marijuana is a drug that comes from the cannabis sativa plant and affects the sections in the brain responsible for thinking, pleasure, memory, concentration, sensory and time perception, coordinated movement etc. A combination of all these centers affected at the same time results with the feeling of getting high and other effects.

Alcohol on the other hand, is also considered to be a drug, because of its chemical structure and a lack of nutrition values. A combination of both marijuana and alcohol effects taking place at the same time is what we consider to be polydrug use. And while you may have a high tolerance for marijuana, alcohol can produce unexpected results when you mix the two.

Dangers of mixing marijuana and alcohol

Drug users think that it is OK to down a couple of drinks and then smoke a joint, or two. What often happens is that the drug user at the end of night is not actually aware of the amount of drugs and alcohol taken, which can result with intoxication.

Alcohol and marijuana act enter the body through different paths and may act differently, but their effects can overlap. Feeling kind of numb, a bit dizzy, losing track of time and space…Both drugs symptoms complement each other. But when combined, weed and alcohol can result in high rate of errors and accidents due to real time functioning and rational thinking impairment on specific tasks. The combination of alcohol and marijuana can results in major impact on the central nervous system (CNS). Here is a list of the most common symptoms:

  • changes in emotional behavior
  • compromised judgment
  • concentration severely drops down
  • decreased attention, perception and memory
  • impaired motor coordination, thinking and problem solving
  • memory loss

How alcohol enhances marijuana – Perhaps it’s obvious, but alcohol acts as a sedative.Alcohol has the ability to act as a depressant of the CNS. Administered orally, it is rapidly absorbed by the gastrointestinal tracts and enters the bloodstream. The alcohol in the blood stream, makes the blood vessels absorb the THC found in marijuana, the active ingredient in cannabis, the one causing intoxication. This action is often the cause for extensive enhancement of marijuana effects. This is why yu may recognize a user turning pale, sweating and vomiting after drinking and smoking marijuana.

How marijuana enhances alcohol – Marijuana, on the other hand, can be administered orally by eating or by smoking. In both cases, the effects vary between individual. What happens is that marijuana doesn’t affect the alcohol absorption in the body, but the alcohol supports the marijuana use effects.

Marijuana and alcohol overdose

There’s really no safe dose that’s suggested when combining marijuana and alcohol. The biggest issue in general is dosing, mostly because both are easily accessible on a daily basis, and users tend to mix weed and alcohol without considering the consequences.

Marijuana and alcohol deaths

The numbers are going up when it comes to counting victims of mixing marijuana and alcohol, mostly those that occur as the result of car accidents. Innocent people are paying the price for other people’s risky behavior. The burden is extremely high when it comes to involving other people’s lives too. Many users of marijuana for medical treatments are advised to wait for several hours before driving or having a drink.

  1. My elderly father has been given a 50% thc and 50% cbd oil tincture for his chronic back pain and insomnia. He likes to have a scotch and soda before dinner. If he normally takes his medicine at 11 am and 11 p. He misses his before dinner cocktail. If he takes the tincture at 11 am, can he have a drink safely at 6 pm? Thanks. Patricia

  2. My friend smokes weed and drinks cognac all day and all night…even wakes up in the middle of the night to puff on his pipe. He doesn’t think he has a problem. I do. What can I do?

  3. I feel slightly down and wondered whether I’m experiencing a combination of marijuana and alcohol withdrawal. When I was on it, it wasn’t bad at all. I would frequently get into the mood of watching porn though, but not always. Sometimes I simply enjoy doing things like enjoying chess. Anyways, as I feel slightly uncomfortable (like, feeling slightly depressed) I came to this site for some info. It’s quite interesting how the body rebounds. My plan is to stay away from drugs (alcohol + pot) for a month, before going to Japan, where I will probably be drinking some alcohol (no weed as it’s forbidden there), but for this month I would like to be as healthy and fit as possible, and save some money in the process 🙂

  4. Last night i drank 2 drinks with dinner and also had water. I felt no effects from the alcohol. Usually my lips get tingly after 1/2 a drink and that never happened. So, without thinkinh about it, a little over an hour and a half later i took 2 hits of weed. I got nauseous so i stopped. Decided to go inside in case i did vomit and a few seconds after i got up i got dizzy and passed out. Had a really fast and irregular heart rate after. Do you think the alcohol and weed together caused it? Or do you think probably not since they were separated by enough time?

  5. Hi Victoria. I’m not sure what you’re asking…are you asking how to quit the weed or how to leave your boyfriend?

    1. Hi, Rahul. Few home remedies have proven to be useful when experiencing marijuana withdrawal symptoms. You may drink cranberry juice to help cleanse the body, and also drink plenty of water and clear liquids. Moreover, eliminate fat from the diet until digestion is better, and you may reduce caffeine.

  13. I am concerned about a friend. I do not do drugs of any kind, so my understanding about this is limited. He is mixing vodka and weed. I’m talking an entire bottle of vodka, then smoking a weed. Does this make you paranoid? He is driving around with weapons…..This is a 50 year old man.

    1. Hi Lisa. Drinking a bottle of vodka alone is dangerous for your friends health, let alone when mixed with marijuana. Both drugs symptoms complement each other, and your friend should absolutely stay away from driving when intoxicated. He needs to understand that in such state he is a danger to himself and others. Can you help him get help?

  14. I am used to smoking bed time joints with my girl friend. We very rarely drink alcohol. There was one night of partying where I was very drunk, and as usual we smoked a fat joint. I was dizzy, nauseous, hallucinating, and vomiting. I almost fell asleep using the toilet as a pillow. It was an extremely unpleasant, mind reeling, out-of-the-body experience which I will never do again. Absolutely horrible. I would recommend that you should not mix, but if you do, take a few sips of alcohol AFTER you have smoked weed, not before. You will feel the powerful effects very quickly, which is why you should take your time drinking so the feeling does not become overwhelming.

  15. Last october, I made the mistake of getting drunk and succumbing to peer pressure to smoke week. I don’t remember anything from that night except puking on the side of the road. Not sure how I got home that night .

    I learned my lesson.

  16. I have a friend who buys a bottle of gin and then places two matchboxes of weed in the bottle. This is left to soak for a few days and then it is drunk. What could all the possible side-effects of this mixture be.

    Thank you kindly.


  17. My male friend just confessed he uses marijuana about half a stick and about 2 glasses of gin mixed with water and ice every night. He calls it his martini time. He claimed it makes him feel good and more relax. He’s been doing this for years. He’s a responsible , retired, financially stable 62 years old man

  18. Hi Poll. Why don’t you get checked by a doctor? I’d suggest going to counselling which can help with the psychological aspects of your problem. While time needs to pass until your brain returns to normal, you can find some memory-improving exercises online.

  19. 7months back i did the same mistake i had overdosed weed and alcohol- the next day when i woke up everything became blurred, i had panic attacks and anxiety.
