Weed Withdrawal

Feeling Hot and Cold After Quitting Weed? Changes in Body Temperature Are Common During Withdrawal

By July 21, 2021October 21st, 202113 Comments

Regulation of body temperature is a critical and complicated process for human health. Deep, highly connected regions of the brain play essential roles in maintaining body temperature within a narrow range around 98° F (37° C). While many chronic marijuana users may be aware of withdrawal symptoms such as irritability or sleep difficulty, you may be surprised to learn that sudden changes in body temperature – feeling hot or cold – are reported by many individuals who have stopped using marijuana after periods of heavy use.

A 2011 study in chronic marijuana users observed increases in body temperature within 48 hours after stopping. These symptoms were reduced after 96 hours (Gorelick et al., Journal of clinical psychopharmacology, 2011). Other research shows that body temperature changes typically start after 1-2 days, reach peak incidence within six days, and can last anywhere from a few days to several months (Babson et al., Current psychiatry reports, 2017).

While the mechanism behind marijuana withdrawal-related body temperature dysregulation is not completely understood, THC has been shown to bind to many regions of the brain responsible for body temperature regulation such as the hypothalamus and pituitary (Cservenka et al., Frontiers Psychiatry, 2018). It is believed that sudden absence of external THC and cannabinoids may disrupt this balance of pathways and hormones in the brain.

Changes in body temperature have also been reported in individuals suffering from cannabinoid hyperemesis syndrome (CHS), a cyclical vomiting illness that presents in some heavy marijuana users. In one study, patients admitted for CHS were shown to exhibit changes in body temperature, in addition to changes in blood pressure, heart rate, skin flushing, and perspiration (Allen et al., Gut, 2004). Interestingly, many CHS patients have reported that hot showers can provide symptomatic relief. The effect appears temperature dependent – e.g. hotter showers provided more relief from CHS.

Suffering from withdrawal-related temperature dysregulation can be scary and may sometimes feel uncomfortable. However, it is important to keep in mind that marijuana withdrawal symptoms are rarely life-threatening. If you are concerned about your withdrawal-related symptoms, there are things you can do to help. First, see your doctor. They might be able to treat your symptoms with medication or identify other, non-withdrawal related causes of your symptoms. Additionally, staying hydrated, exercising, and practicing good sleep hygiene may help make you feel better.

About is a free, web-based resource and community created by a team of healthcare professionals and researchers. We distill the facts about marijuana use and its effects into practical guidance for interested persons or for those who are thinking about or struggling to quit weed. Finding reliable, easy to understand information about marijuana should never be a struggle—that is why our core mission is to provide the most up to date information about marijuana use, abuse, addiction, and withdrawal. While we seek to empower individuals to have control over their use, we are not “anti-weed” and we support efforts to legalize adult marijuana use and study.

    Thank you for this awesome trove of info – I quit smoking 2 days ago after years of heavy use and have many of the withdrawal symptoms listed. I had no idea my poor sleeping and gastric upset and crankiness were related; thank god I found this site and now know that MJ withdrawal is a real thing and I am not losing it.
    My friend and I decided we have an addiction problem and decided to stop for 2 weeks; well after 2 days of feeling funky and reading the withdrawal info I am going to stop for good!
    The MJ being sold in stores (legal where I live) is so GD strong compared to the stuff I smoked back in the 70’s and 80’s – the hybrid stuff especially. I frequently light up during the day and immediately feel weird and antisocial then I wish I wouldn’t have . . . so stupid

    • runtz says:

      just smoke strains that don’t have a lot of thc. there are a lot of (mid) strains that have 10-20% thc there way cheaper than the heavy strains you could also use cbd as it’s not nearly as strong as some of them exotic strains.

  • Not really says:

    It’s true. Even after the first time I stopped weed, other times still surprised me as to how bad I feel.

    I smoked like 1 joint a day mixed weed and tabaco. Mostly in the evening. Stopped, and I am now lying in bed with fever, body ache all over my body. Had the worst sleep ever. F*** weed really.

    After a few days I will feel better but it takes months to get used to activities without weed again. Even after months you are still at prime state to meet some friend, and think to yourself: just once.

  • mr. poopiebutthole says:

    interesting read, I’m currently drenched in sweat, haven’t ingested thc in 48 hours after using concentrates and edibles heavily over the past few years. Every time I quit this happens especially at night I’ll wake up 3-4 times to shower.

    I cannot believe how people sell this substance with a straight face and recommend other people to use it under the guise of recreation. It’s incredibly easy to get addicted when you have cheap access to legal cannabis, and the substance modifies your sense of self in ways you wouldn’t even wish on your enemy. I have suffered immensely from my addiction and trying to quit several times, only to fall back in from the horrendous withdrawal symptoms and the worst part is it makes you guilty, antisocial and paranoid so you avoid talking to others when you need them the most. I have an Engineering job that suffered as well, but I haven’t been defeated. I will keep fighting until I regain agency over my body and mind, absolutely disgusting how pot head losers encourage other people to join them in their slumber (because this drug helps you stay asleep and stop caring about the world and your dreams instead of facing challenges head on and reaching goals. It removes any willpower to even lift a finger beyond instant gratification activities). Stay away at all costs, you have been warned.

      That’s a negative view. Cannibis is a great tool if used correctly with discipline however most don’t put in the hard work and get anxiety

      • Mark says:

        It’s not a negative view, it is a personal opinion on how it has affected their life. While Cannibis ‘may’ be great for some people, people who have addiction issues and other mental health issues that aren’t fully understood may not have the positive experience you have. Not all people possess the discipline you may have (kudos to you).
        I was sold on medicinal use in my state after years (12+) of hard work with therapists, psychiatry visits, countless failed attempts on SSRI’s, and many emergency room visits. I was told Cannibis wasn’t addictive, it was safe, and there were strains to help me accomplish just about anything, so after years of failed attempts to get my mental health right I tried medicinal THC.
        In the beginning I felt like Superman, was this what life was like without anxiety, panic, PTSD? As the months went on I noticed that ‘good’ feeling started to fade even with regular usage. I was told I needed a higher percentage THC. Fast forward to 4 years later, and I am now at the lowest point in my life because of Cannibis. My mental health, panic attacks, and PTSD are so severe I can barely leave my house. THC made it okay for me to isolate and accept my mental health status as is instead of trying to heal and get better. I was okay with being bored, complacent, and where I was at in life so I quit school. I was less than a year away from my BA and all the sudden I didn’t want to be bothered by anything in today’s world, it was just myself and my Cannibis. I’m sorry but that’s not reality.
        Luckily, I am 1.5 months free and I am gaining back the power over my mind and body little by little. I lost 21 pounds, my blood pressure is back to normal, I want to get back into the gym, I want to finish school, I want to socialize and make friends again, and I want to be happy.
        No, Cannibis is not horrible for everyone, it may even work wonders for some people, but what I hear more often than anything is the love people develop for it and how quickly it becomes a top priority.
        If you’re struggling don’t give up, it feels so good to be living again and working towards goals.

      I think this is a personal problem. I guess I am just a pothead loser who owns a 7 figure business because I don’t care about my dreams and I don’t face challenges head-on or reach my goals. When your willpower is at 2/10 anyway and you smoke, yeah maybe. But that is about YOU. YOUR willpower. And I have never relapsed because I am not weak. I mean, you act like you’re going through hard drug withdrawals. Oh wow, you feel like shit for a week or two because you made the choice to use a drug irresponsibly and became addicted at your own will. But on a real note, I hope you have found peace with it and worked something out that works for you. Just had to say something because you want to blame others for your weakness. and also, if your friend was like hey want to try some meth would you just blindly believe them and think it’s awesome? How about you think for yourself and make decisions based off research? But hey what am I just a pothead loser right? LOL

        I respect this. It’s not about weed but the person smoking the weed. If you can be productive and smoke weed, awesome. But if you can’t be productive and smoke weed, and you CHOOSE to smoke weed over being productive, that’s on you, not the weed. Weed doesn’t roll itself up and spark itself up, it doesn’t force you to inhale or ingest. If you make the choice to put the WANT of smoking weed over the NEEDs that need doing, the failure is on you.

        I say this as someone that’s currently on day 3 of quitting. I have to move states for a new job, and they drug test for weed there. Sure, the hot flashes and sweats are terrible, but I CHOOSE to get sober and to get a well paying job with benefits over smoking weed with a worse job and worse benefits. It’s all about choice. If you choose to do something, it’s always on you. I’ve had to quit 3 times before. Every time things got rough while I was sober, I would just remind myself that I and my success is more important that smoking weed.

        I feel that everyone should feel that way, but again, if you CHOOSE to put smoking weed over yourself and your success, that’s on YOU.

    I have had just about every symptom but the abdominal pain is the worst. I’m 3 days clean, hot flashes are beginning. When I first started using MJ I was in control, I could stop easily didn’t use it every day and was able to just enjoy it recreationally. Then I begin to have an addictive behavior towards it. I never really had a great appetite and MJ definitely helped me to eat and gain weight. Then I started to smoke on the wake up and that’s where the smoking turned into an all day event.
    I truly believe it is very easily to become addicted to anything once you just focus on that one thing all the time. If you know how to dose yourself and actually control yourself then your good (like my fiancé, he can quit instantly with no problems). Outside of that if you know you have addictive behaviors then just stay away from anything that’s going to bring you strife.

    I have been an after work user for almost 10 years, weekends I use more especially when the kids aren’t home. I have not had any adverse consequences from it. I still wake up, go to work everyday, pay my bills on time, take care of all my afult responsibilities, invluding the kids. I have vaselated between pre-rolls, edibles and vape over the years. I am just tired of waking up every morning wishing I would stop using it so much. I recently got sick Monday and since I could not smoke for 3 days due to the illness, I decided nows a good time to stop. absolutely could not smoke for 3 days at least. Iits only been a week, but my only symptoms have been difficulty dalling asleep, and possible low body temp, and I don’t even know if that is from the lack of weed or my illness. all I know is, so far it’s been easier for me to not use than any other time I have quit in the past. maybe being basically unconsious for the first 3 days helped, and if thats the case, I suggest if stopping is difficult, maybe try a time when you are very sick. It’s only been a week, I know, but so far its been the easiest time I have tried to quite, but I also dont have an addictive personality, so mybe I have just finally decided this is it, I am done letting the weed win. I already feel much more clear headed, and motivated to do things and that started after just 3 days.

      Yeah I’m on days 3 I’m sweating a little bit more than normal but I naturally presperate a lot especially under my arms pits. Once a years I stop for 7 days I notice my appetite isn’t as strong. But what really helps is me working out I try to stay pretty active. But it’s not bad tho. When I start back smoking I like to do but ima turn it down a knotch to like 4days out of a week cause I do enjoy it but I don’t want it to consume me

  • Weedlover333 says:

    Day 5 of quitting smoking weed after doing it for almost 2 years everyday twice a day none stop. I thought weed withdrawal wasn’t possible or if so just mild nothing crazy but this is very very uncomfortable. The sweating,chills,nausea fever, loss of appetite it’s all very much true especially with the new weed today I’m only 20 so the weed I’ve been smoking isn’t like what any of you old heads use to smoke so just imagine. I quit cold turkey so if you’re a heavy user I suggest not quitting cold turkey and if you do then i recommend you stop at the store for some pepto, ibuprofen and lots of water because you basically have the flu.
