r/CannabisHyperemesis

Today is 48 hours of no smoking (cannabis and nicotine) finally was able to get some sleep (about 5 hours) still feel nauseous but not quite as bad as the last few days but abdominal pain is still present eating is still hard and my stomach is constantly churning (haven’t eaten in about 5 days)

I’ve been having harsh sensitivity to temperature feeling extremely cold until I am wearing multiple layers and begin sweating which feels ice cold and does help

This has caused me fear of taking hot baths as getting out feels unbearable.

Any encouragement or advice is appreciated 🙏

Prequel:
I’ve been smoking everyday for about 5 years now, started when I was 18 and noticed it helped me sleep at night which I’ve had problems with since I was a child. I smoked 3-4 joints a day with 0,3 grams of hash in each. Got my first chs attack when I was 20 so 2 years into smoking. It started with a terrible stomach pain that got me admitted via ambulance to the ER only to let me go after about 2 hours of obsevation and no concerning test results on bloodwork and so on. Got admitted again only two days later cause I couldn’t stop throwing up and eat or drink anything. The doctors couldn’t help me at all and I had to ride the sickness out which took about 5 days. Fast forward 3 months and I moved back home to my parents due to apartment complications for at short time. I stopped smoking completely but got sick again after a night out drinking. I was sick for about 7 days and got admitted to the ER again where some doctor suspected it was CHS due to my earlier smoking patterns. I didn’t get sick for another 6 months. When I moved back out from my parents I got sick almost instantly. I smoked a bit at home at night sometimes when I couldn’t sleep but never during the day or more than maybe 0,1-0,2 grams of hash. I started getting sick almost every other month with episodes that lasted for 5-9 days. It was hell and as an already small girl took a toll on my health and eating habits. (Sidebar- almost every CHS attack I had came a day after drinking alcohol)
Now to my question;
I’ve relocated to a place where it isn’t so safe to smoke at day without neighbours and others intervening or calling police so I’ve gone down to only smoke at night, I share a joint with my bf which contains about 0,3 g of hash so on average I smoke 0,15 daily now. I haven’t had any episodes for a couple of months now but fear the next one (and fear I may psych myself into it) I’ve tried several t breaks which only last about a week before I start again. I don’t need to be high or anything during the day but I can’t let go of my nightly spliff, it’s a part of my rutine by now and helps me so much with anxiety and racing thoughts during the night. Does anybody have experience with CHS that smoking less and taking more t breaks actually does free you from the CHS attacks or is the only cure to stop completely and never touch it again, not even just a little puff every 6 months? Weed doesn’t control me and I don’t need it to function during the day, but I still hope that I don’t have to completely give up smoking as I see the benefits quite clearly on my everyday-health.

So I think it’s about that time. I always blamed it on the food I would eat and after being real with myself I don’t feel good after I smoke and my stomach is always hurting. I’m straight up addicted tho been smoking almost a decade now but it’s like the anxiety and stomach aches are just increasing and I really don’t wanna get to these scary stages people are talking about

Question: so if I’m a daily all day every day dab pen user but is there a way I can slowly stop and still avoid chs? Like maybe start by taking a day off then maybe 2 days off i don’t know I want to be able to smoke on occasions but I also don’t want to send myself into one of these scary stages. Absolutely hate that weed has to have this scary side to it :(

I also want to ask how does this throwing up stage start ? Like is it abrupt? Like your stomach hurts throughout life and then the next day your in a crazy puking brawl?

I’m 18 years old and I recently found out that I had developed CHS and was in the prodromal phase (stomach pain, anxiety, anxiety about vomiting, nausea) and I stopped smoking altogether. I have been 2 weeks sober, and I have some questions. If my condition didn’t fully develop into the hyperemesis phase, am I able to start smoking again but recreationally? I used to be a heavy cart user, getting high almost everyday, and now I’m completely sober and am thinking about the possibility of having a puff of a joint every here and there, but I don’t want to make myself sick. After a month I intend to try a bit of a joint, but I wanted to ask about others experiences with CHS. Thank you for your time!! :)

Officially over 100 hours sober from weed for the first time in about 7 years. I averaged 20-30+ dabs a day, (usually 7-9 before 9am) live resins ~90-95% thc and live rosin typically 75-83%. I never thought I could do it but after these episodes I’ve been getting and ER visits I don’t think I’ll ever smoke again. I am feeling so much better overall, I’ve had about 12 episodes in the last 2 years, never believed it was weed thought all my doctors were crazy but I finally opened my eyes

This is my first Reddit post and I hope this post is relevant!!* TW discussing thr*wing up

Hi, so a little back story, I was a daily smoker of just weed and tobacco in a joint (3/4 joints a day) for around 7 years, I would smoke before college, after college, before work, after work etc, It became a massive necessity in my life. About a year and a half ago I had to stop smoking for like 4 days and as soon as I hadn’t smoked for a day I woke up the next morning with severe stomach pain and v*miting multiple times every hour I couldn’t eat or drink anything and I would still be thr*wing up stomach acid, this went on for around 2/3 days before I had to go to A&E due to severe dehydration and had to have an iv drip etc, I was sent home the same day, the next day it was still occurring and I was still being sick, so had to go to a&e again for the same process of rehydration and a drip, I ended up being told to go on a liquid diet for a couple of weeks and that I had ‘gastritis’ but I am wondering why it all started as soon as I quit smoking? I had to get an endoscopy a few months later and had acid burns at the bottom of my oesophagus. And btw a week after I was sent to A&E i started smoking again and my symptoms subsided anyway so I was back to daily use, skip forward to January of this year (2026) I stopped smoking again cold turkey and the same thing happened where I was having severe stomach pain and thr*wing up so had to go to A&E was diagnosed with gastritis and IBS and been taking omeprazole ever since, I ended up stopping weed entirely, and my symptoms eventually subsided but the night I came home from hospital I tried to smoke and had a massive panic attack with shakes, palpitations and literally thought I was dying it was so scary, I don’t know if it was because I was given morphine in the hospital and it was just a bad reaction, so I decided to stop entirely and I felt better but It came with a lot of mental difficulty with panic attacks and anxiety attacks about my heart and health to the point I was calling emergency services quite frequently and had to quit my job and move back home with my parents, I couldn’t go anywhere or stand up for long without feeling like I was going to pass out and it lasted for a few months I’m better now and managing daily life again (not sure if that is relevant to this sub but just thought I’d mention it sorry) but I was just wondering if it was CHS or just a very very bad weed withdrawal or even nicotine withdrawal? I was continuing to use a vape while I quit so not sure it was nicotine but worth mentioning, it’s been over 5 months since I last smoked and recently just started smoking cigarettes, will I be able to smoke weed again? Or will the panic attacks come back if I try? I’m really scared about the mental health side of it as it was honestly one of the worst experiences I’ve ever had to go through, I just want to be able to smoke once a month or something and feel good again, life is just so crappy without it and I still miss it a lot lol I know it sounds stupid but I don’t drink and have (diagnosed) ADHD and a musculoskeletal issue that causes severe nerve pain and joint pain and was using the bud to help manage the pain and symptoms of my ADHD as I have a very active brain that I do not like I have a tendency for anxiety but it was never bad enough to cause panic attacks like I did when I tried smoking again as I believe that was my first panic attack, weed was always nice to shut it off and just relax, I don’t take traditional medication as I’ve got a fear of tablets due to a surprise allergy and haven’t been able to take medication for anything since literally have to take calpol if I’m in pain, I just miss it quite a lot, so yeah to summarise -

Can I still smoke again without having panic attacks?

If I do smoke again one time will I get the same issues with my stomach?

Is there a way I can ease into smoking again to make it easier on myself mentally to avoid the panic attacks?

(Sorry if this is not relevant to the sub or the way I have written it I’m not great with writing and prone to yapping a bit lol)

I am Male, 18Y, 5’7, 55KG

About a week ago I started having extremely fluctuating eating patterns from a intense feelings of hunger to loss of appetite causing overeating and vomiting about once every day generally in the morning or night along with feelings of nausea and anxiety (I have underlying panic disorder, anxiety disorder and low mood)

About 4-5 days ago I began vomiting more frequently in the morning and at night with more extreme nausea and abdominal pain I went to the doctor who basically said it was all in my head and prescribed me Lansoprazole which after taking a couple times I found ineffective.

Yesterday I went to the Emergency room due to concerns about my hydration got my blood done which came back regular and was prescribed Ondansetron however when I went home I vomited in the night and the next morning after taking the anti sickness.

While i was there the nurse asked if i smoked cannabis which i have been doing daily for about a year and a half and began researching CHS

2 of my cousins were diagnosed with CVS about 4 years ago which was changed to a diagnosis of CHS recently however both continue to use and are underweight and suffering severe health complications.

My symptoms are confusing me as the morning/night sickness is a symptom of CVS and hot showers haven’t felt overly beneficial though I am struggling with temperature regulation (feeling cold when wearing multiple layers)

So far I haven’t eaten or slept in 4 days and my mental state feels as it’s declining due to seeing how badly this has affected my family and the potential of permanent CVS

Can anyone help differentiate between the two better to and does anyone have any advice

I am currently 36 hours sober since A&E from both tobacco and Cannabis, I would also like to ask although not advisable would I be safe to smoke a nicotine vape until I am mentally able to give up the cannabis addiction and general smoking habit and symptom’s subside because the idea of ceasing both cannabis and nicotine while dealing with this is very daunting and would taking Escitalopram or promethazine be advised?

About 8 weeks ago, I was in the ER twice. Long story short the most logical explanation for my symptoms is CHS. I was only smoking carts. Used to smoke flower too but honestly I just got lazy. I haven't smoked since 3-21-26. I plan to go 90 days, then I want to try a small dose of flower. Is this a mistake? Is there no going back once you have it? I know I can never use in the same capacity I was previously (which was all day everyday) but can I go back to enjoying some flower when I take a walk on the weekends? Or am I really done forever?

Morning yall, this is my first post here. I’m currently coming on to what I believe is probably my 5th or 6th episode with CHS. I keep relapsing and while that within itself is a huge problem my main concern and questions today is what pain management methods work wonders for you guys? I’m a heavy user of the capsaicin cream and hot showers but the pain is so unbearable most flares that’s it’s really just gritting my teeth until it passes. If you guys have any suggestions I’d love to hear them

Does anyone know how common this disease/syndrome is?

I personally had two of my friends who also had it medically diagnosed , but i feel like i know some other people who probably have it and are in denial about it. The hard part is the prodromal phase, which can be more subtle but also de habilitating (lack of appetite, stomach pains, general nausea).

What percentage of daily weed smokers get this?

I think there should be educational posters in every dispensary in america educating people about the symptoms of CHS, because i feel like so many people i talk to have never heard of it.

So for 4/5 years I’ve had stomach issues.
Abdominal pain always in a morning that will usually subside and I’ll feel normal by 12 oclock.
The stomach pain is intense and feels like my stomach is eating itself / a washing machine.
It makes me nauseous, dizzy and disoriented it makes my anxiety through the roof and I’m now struggling to work or even enjoy my hobbies or food at the fear I’ll be sick.
Obviously weed is the only thing that helps.
Now over the past year the pain on a morning has gotten worse and I’ve began to wake up in the middle of the night being sick. (Most noticeably 4 nights ago I threw up 8 times in 5 hours)
The pain has stopped subsiding by 12 and generally is an issue all day everyday now.
Well until it just randomly disappears then returns randomly again.
I’ve had gut issues related to diet which I’m working through and this has improved some symptoms. But the pain and abdominal issues are still relevant.

Do these symptoms sound like CHS?? The shower does help but doesn’t fully cure the pain.
I also believe I have parasites so will cleanse for those.

I’ve smoked HEAVY for 11 years now so I know I need to stop and I want to. But I don’t want to stop forever and that’s why I need a definite answer is it the weed killing me off or am I blaming my comfort?

Can’t wait to hear some opinions anymore explaining I need to do please let me know

Last week, Tuesday night into Wednesday morning, I got hit with another CHS episode. Probably my 10th or 12th one at this point. At some point you stop calling it “bad luck” and realize your body is basically filing formal complaints against you.
Still recovering. Slowly getting better every day. Eating potatoes like they’re Michelin star meals. Shoutout to boiled potatoes. Didn’t know that was where my life was headed.
A few things that actually helped me:
Hot showers

Capsaicin cream on the stomach (lightly… unless you want to feel like Satan is doing hot yoga on your abdomen)

Constantly sipping water while puking. Weird strategy, but I usually kept more down than came back up.

Things that did absolutely nothing for me personally:
Zofran

anti-nausea meds

patches

lidocaine patches

basically everything they hand you on the way out the ER door

Here’s the part that’s probably important for some people reading this:
I’m probably 3–4 years into this cycle.
At first I thought it was something else. How could it be weed? I convinced myself it was cyclical vomiting syndrome for probably a year. Honestly, some of the doctors did too.
Part of that was because I wasn’t fully truthful about my weed use. Part of it was because I genuinely didn’t see the correlation. When something becomes part of your everyday routine, your brain stops viewing it as a possible problem.
Then eventually the pattern becomes impossible to ignore.
And the weird realization is this:
I wasn’t smoking to party. I was smoking to feel normal. Quieter brain. Better mood. Food tastes better. Music sounds better. Life feels softer around the edges.
Then one day you realize the thing helping you “feel normal” is the exact thing making you not normal anymore.
What finally changed for me wasn’t the puking. I can handle suffering. It was watching what this does to the people around me that care about me. Wife. Kids. Family. Seeing them worried while I’m laying there looking like a haunted Civil War survivor.
So here’s the plan:
No smoking. I’m gonna stay off it until I can pass a piss test, then probably stay off another couple months after that and reevaluate life with a clear head.
And honestly? Sobriety sounds kinda peaceful right now.
Also, moderation and me historically haven’t exactly been teammates. If I like something, my brain’s natural instinct is:
“Cool. Let’s do all of it.”
I’m not some burnout stereotype either. Professional career. Wife. Kids. Responsibilities. Which is exactly why I wanted to post this. A lot of people dealing with CHS are functioning adults who slowly normalized being high all the time because it helped them cope with stress, quiet their brain, sleep, eat, whatever.
Until eventually your body taps out before your mind does.
Life’s a giant experiment, I guess. I’m just trying to stop running portions of mine in constant pain.
Hopefully this helps somebody else break the cycle a little sooner than I did.

I'm 20F, this year in late Feb I suddenly had an intense vomiting episode where I was puking, which then turned into dry heaving up stomach acid every 10-25 mins. I was super stressed as I was on my way out of town to see my grandma that was dying. After that I had another episode week later, and I've had an episode almost every week since then, same throwing up to dry heaving every 10-25 mins, and each episode last about 10ish hours. I have had similar episodes once or twice as a kid due to stress from surgery. After these episodes I struggle to eat solid foods for about a day and struggle with low appetite for a day or two, with THC being the only thing that usually helps the no appetite and can usually help me actually eat solid foods. I smoke daily and haven't noticed it getting worse or better. I smoke due to a lot of health problems, both physical and mental. I went to the hospital two days ago due to an episode and they said I probably have cyclic vomiting syndrome, and my potassium was critically low. I never really had a phase before the first episode in Feb where I had intense nausea everyday, I only get symptoms the morning of an episode. Could this be CHS? Should I try and stop for a period of time and see if I see improvement?

I’ve had 3 episodes over the past 4 years. Recently started smoking again and I have extreme bloating, nausea & anxiety right now. I only hit my pen twice earlier today, and already threw it out. I am done, but I’m terrified I will still go into hyperemesis even though this morning was the last of it for me. Do you al think I can still potentially hit hyperemesis or not, if I don’t touch it at all anymore?

So I’ve been heavily using THC/weed in drink form and an edibles for some time I started April 2025 and then I stopped around January 2026 the reason being is I was about to consume a THC drink and then I noticed my chest felt like it was fluttering. It felt like it’s hard to explain, but it felt like an uncomfortable chest feeling where I had to jump or shake my arm or kick my leg in order to feel comfortable kind of like the feeling of fight or flight, but then it subsided a little but this occurred for months and it’s still going on, but not as strong being that I stopped using in January 2026 I went to a cardiologist. I got multiple tests one for my kidneys, one for my heart called an echocardiogram to be exact. I got in heart monitor and I wore it for two weeks and I got blood work and I did an exercise test and all of my test came back normal. I take beetroot and magnesium and omega fish oil to try to get the symptoms to stop. They subsided a lot and they’re not as strong but I remember when I stopped around January 2026 I noticed that I got out of breath more quickly and my heart would beat fast and more quickly so if you guys have any recommendations, please, please please help it’s hard because whenever I try to go to sleep and wind down and relax it’s like that feeling where it feels uncomfortable in my chest kind of a fighter flight feeling where I have to jump or shake a body part in order to feel comfortable because I can’t sit still with the uncomfortability in my chest. I would love to consume THC again being that I stopped drinking alcohol, I will admit I was abusing how much I was consuming, but my question is do you guys know any ways or have related to the feeling that I’m talking about and maybe some possible cures for that? and also, do you guys recommend using THC again or weed just in moderation maybe once every two weeks or twice a month instead of every day, also to add if this helps my blood pressure was high, but that’s expected from weed, another thing is whenever I consume caffeine such as coffee now it triggers that uncomfortable feeling in my chest like I’m sensitive to it now, but please help!!!😭😭

I’ve had CHS since 2015, but this week was terrifying. I went to the ER after 24 hours of vomiting. They gave me IV fluids, Gabapentin, and Ativan.

​I had two separate "attacks" where I couldn't breathe, my throat felt like it was closing (with a loud snoring sound on intake), and my muscles constricted so badly I could only lean to one side.

​The first attack happened Sunday evening, and the hospital staff witnessed it. Despite that, I was still processed for discharge. Then, early Tuesday morning, it happened again. While I was waiting for an Uber in the lobby, I had another attack that was so severe the lobby staff called a nurse thinking I was having a seizure. Instead of re-evaluating or stabilizing me, the staff simply escorted me out to my ride.

​I ended up having to take Benadryl because I remembered it being used for similar reactions in the past, and it finally helped the symptoms subside. I’m honestly afraid that next time I won't be able to catch my breath and no one will help.

​Has anyone else dealt with a hospital ignoring a clear medication reaction or respiratory distress during discharge? What were these muscle/breathing symptoms?
