r/CannabisHyperemesis

i’ve been smoking weed since I was 16. started using daily when I was 18 (i am now 21). my method of choice was always carts and i’d get to smoke bud whenever i’d see my dad. I started noticing nausea around March, it was daily and persistent. I could still eat, bowel movements were still normal. I got checked out at the docs and everything came back normal. sometimes the nausea would go away for a few weeks and then return. at first I thought it was because i was trying to chief really low carts (probably still a contributor) - but now the nausea comes when I smoke any sort of cart. i’ve been doing more research into CHS bc I knew someone who had it and was worried i was going to end up with the same fate and am even more worried seeing now it can start with just nausea. stumbling upon that discovery i was hit with a panic like no other. as someone with very severe emetophobia (fear of vomit) I truly don’t know what I would do with myself if I made it to phase 2. I haven’t vomited in over 10 years. so, i’m quitting. but my question is - if I stop now and never smoke again, I can’t get into that second phase right? that’s what I’m
most concerned about.

f17, i started smoking everyday only last year, i would constantly smoke at my bfs house, and then go back to my house where i couldn't smoke. i noticed around 5 ish months in that everytime i wasn't high, i would feel nauseous, and everything tasted like cardboard, i eventually ended up finding out what chs was, convincing myself i had it, and quitting. couple months later,i moved in w my boyfriend, said i could do moderation (we all know how that goes) then pretty quickly i was back to everyday. this lasted for id like to say 2-3 months, i started noticing very quickly that i would wake up in the mornings feeling nauseous, stomach making wild sounds, but after i had my first bong of the day, it would go away. now just last sunday night, i ate a big meal before bed, and realised i felt kinda uneasy. woke up the next morning THE WORST NAUSEA fully convinced and preparing myself for my first ever CHS episode. Thankfully, i didnt end up vomitting, but the second i felt that, i decided i knew i couldn't handle an episode, and i should quit now before it starts. but im in such a pickle because all of my friends that smoke weed say how can i have got chs so early into smoking? and i dont even use carts or oil or anything only bong and flower, it sucks because the more everyone says like "oh you know you do have health anxiety, so your probably making urself have these symptoms" it makes me feel justified and maybe itll be ok and i can smoke. it sucks because i dont want to quit, but i dont want chs, id rather quit before its too late, but i have the feeling of, what if it was anxiety or another issue and im quitting even tho i dont have chs? i know im in denial but i guess i just need some advice.

also i dont know if genetics do have a link but i come from 2 people who never touched it before i was born
i also never had any prior stomach issues until i started smoking daily

Hello,

I’m 24 been smoking every day chronically since I was basically 15. Carts, flower, concentrates,etc. I’ve always been slightly underweight and struggled to have appetite but I would say it comes and goes. Recently as soon as I open my eyes after waking I get nausea for about 30 seconds until I sit up. Questioning if this is early sign of chs taking into account my low weight and appetite. No throwing up just nausea in my first minute of waking followed by low appetite for breakfast. Would tapering down to only a couple puffs of a joint at night instead if all day use and eventually trying to quit help? Or is full cold turkey the only way ? Any remedies that will help with withdrawal, symptoms, staying on track?

Thanks

I’m a nurse in an Emergency Department and I’m here to ask some questions to those suffering from CHS.
I take care of several CHS patients every week. I can usually tell when someone is CHS when I first meet them. Extreme abdominal pain, cyclic vomiting, and they usually have a very strong marijuana odor. I’m not generalizing and I have never written someone off based on what they smell like. We will always check for other causes.
Any way

Why do most CHS patient deny this diagnosis so much? It seems like they don’t believe the doctor when he tells them what’s going on. Which leads to my next question

why not stop? Usually CHS patients come to the ER several times for the exact same thing. I know this is sometimes because they don’t believe us, but wouldn’t it be worth just not smoking? Considering how severe the symptoms are?

Side note: please don’t lie about your usage. We do blood work and a ct scan on almost every patient with abdominal pain, if it’s something else, we will know. We are not out to get you or punish you for using marijuana. We really don’t care what drugs anyone uses, And we’re not the police.

Another side note: Ask for a med called Droperidol, It works wonders for the nausea and will help you get some sleep.

Thank you

I am a daily smoker (only bud) for around 4 months now, I previously smoked but stared again after a 2 month break. I would smoke 2/3 maybe 4 spliffs a day always in the evenings. About 3 weeks ago I noticed that I didn’t enjoy eating food unless I was high. I would also struggle to eat a lot when sober and started skipping meals to wait until I was high. I went through quite a stressful period and one day before work I woke up at 6 am and started vomiting yellow bile; assumed this was severe stress. This got better during the day but I was struggling to eat anything and would only eat when stoned at home. This cycle repeated itself to the point where I was shaking and shivering in bed and my stomach was cramped and I was constantly vomiting / nauseous. Ended up in A&E dehydrated. Nothing stopped the nausea not even the ondansetron tablets, only smoking. Also smoking is allowing me to drink and eat the bits of food I can. Blood tests and urine tests are coming back fine. I am due to have an ultrasound soon too. Just wondering whether this could be CHS? If so, I’d love to quit but is it better gradually or cold turkey. How many days will it take to clear my system? How many days will I have to live with the vomiting?

Hi, i have suffered fron CHS for about 3 years now. I got diagnosed on behalf that I smoked approx. 1 joint a day to sleep. Further tests and whatsoever were never made because og stigmatisation involving cannabis in my country. I used to be sick every month for about 7-9 days and was frequently emitted to the ER because of dehydration. For 3 years I was sick every month- now I have moved to another appartment and even though I haven’t changed my smoking pattern or any other things concerning my health, I haven’t been sick with CHS (or symptoms) since moving which was about 4 months ago now. I felt like an episode coming on right before moving but the symptoms disappeared as soon as I moved. The apartment i lived in before was a minor health hazard due to possible Black mold and penetrating damp** **in the Walls. I also had a problem with my landlord who frequently came by unannounced, texted and called at any hours of the day and honestly gave me a lot of stress and made me paranoid of being watched. Now that I have been without an episode for so long and that pattern of monthly sickness is more and more far away I sit and feel that I might have been misdiagnosed and that the problem wasn’t the cannabis but other factors in my life. Has anybody heard of something similar or out of the blue been cured for CHS without making a difference in your smoking habits.

Helloooo

I (22 F) have just been diagnosed with CHS as of a couple weeks ago. I immediately threw out everything I had and quit smoking because my symptoms were so debilitating and it was just better for me in the long run. However I have lost a significant amount of weight due to having a two week long episode where I barely ate anything. I was just wondering if any of you who have recovered/are recovering have any advice as to how you gained your weight back and what are some things I could do to get back to a healthy weight? I have been drinking at least 2-3 protein shakes daily and have been trying to keep a normal meal routine. Please let me know any advice you have!

I’ve had a weird experience with chs. I used to be in the military and would smoke once a month the day after drill for about a week. One day I felt sick and threw up for 8 hours and they called it chs when I went to the ER. Kept it going and six months later had to go back for same symptoms even tho I went four weeks without smoking and there was still some in my drug test and they said it was chs again. After I finished my contract and got out, I smoked for two months - one bowl in the morning and one -two in the afternoon. Sure enough, two months later I was back in ER and this time it was way worse. Since then I cut it out completely and feel great. However I’m going on a trip soon and wanted to smoke one of the days I’m on the trip. Could one day risk the symptoms flaring back up? Or will as long as I don’t smoke an absurd amount and literally smoke like one blunt or hit one bowl will I be okay?

I wake up randomly at 2-3am and my body gives me 30 seconds to get to the bathroom so I can throw up.
99% of the episode are in the middle of the night, only a couple early evening while I was awake and not in bed.
75% are followed with a migraine.
Both the migraine or vomiting episodes put me in first gear most of the following day.
I read that people have real time or soon thereafter episodes, I have not yet heard of instances like mine where it’s later in the day, hours after taking the last toke. My dr feels my symptoms are caused by CHS but I also have “slow stomach emptying” issues from a major hiatal hernia on my stomach. Separate issue that I have a dr for also.
Thanks in advance for your answers.
EDIT. I had a 5 month complete break from all weed due to a surgery and recovery and I was still having these symptoms. So mentioning a T break, won’t do it.

i started smoking june 10 2025, mainly carts ( bad i know ) this july and i notice im going through my carts quicker than normal, and i was slowly trying to smoke less and less. i always had a very very big appetite and i noticed it started going away ~a month ago so i said once i finish this cart im done because i didnt want to have a dependency. my whole life ive always had nausea due to anxiety, so when i started feeling a little nauseous i kinda ignored it, but i started stopping smoking as much and trying to do one day sober and the next day i can smoke because i didnt think it chs a possibility because i just smoked a little more than a year regardless, i quit cold turkey 4 days ago and i dont know if its the weed or if i have another sickness / possibly acid reflux.. but the day after i stopped smoking i threw up more than 7 times and i hadent even ate anything before i started throwing up, i was literally scared because every hour i had to vomit, no matter what i did or didnt eat. and if i fell asleep i would wake up 4 hours later to puke, the only things i had aten all day that day was just some water and applesauce because i kept throwing up RIGHT AFTER I WOULD EAT. Obviously at this point i was looking into just about anything to see what it was, seen chs and chs relief and decided to take a hot shower but i still felt nauseous even in the shower. i couldent sleep ( i started smoking due to pretty bad insomnia so i expected this) and i started to feel almost normal again so i resumed normal life with eating and drinking until it hit 10am yesterday. i felt so nauseous and i was scared to puke which obviously dosent make it better when i get anxious i get more nauseous, so i took 2 dramamine and fell asleep and now i feel “fine” besides the semi-constant nausea but my mom said it’s probally because im constantly anxious. i’m trying to still stay consistent with my eating because i hate feeling nauseous due to a empty stomach, but every second i feel like i could throw up all it takes is one gag. both hot/cold showers don’t really relieve anything so idk if that means if its chs or not, and im not having any stomach pains or anything else besides the nausea. although it was scary it didn’t feel like i was dying or had to get urgent help, but im still scared it will happen again. Is this possible symptoms/signs of chs? i’m kinda scared to go to a doctor because my mom dosent know i smoke 🙃 i also have big events coming up so im trying to convince myself it’s just my anxiety for the events. any advice is greatly appreciated

Had previously gotten chs as a result of smoking lots daily for years and went to the er a total of 3 times in one week, which I had to be connected to an iv for my potassium. Been clean for about 2 weeks and 4 days since then and it’s been really upsetting me that everyone says you can’t go back to smoking ever again. I have plans to see friends tomorrow which I normally would do before chs, and I’m wondering if even just a puff will send me into a full blown episode again? I’m out of the active vomiting stage and have been able to hold food down that normally would’ve triggered an episode. Alcohol seemingly has been the biggest trigger, but prior to seeing a doctor I was able to have one bowl without pain or throwing up. Just curious if now that I’ve waited this long that it would be safe to try again? From what I can tell the oid wasn’t what triggered it. I’m on medication for it (ondenastron and pantoprazole) and haven’t had any symptoms whatsoever so I think I’m recovered. Can I do it in moderation or prep in any way to make it safer to do?

Hi all. I've been a regular vaper of cannabis products for almost 5 years with brief breaks in between. This past week, I think I experienced cannabis hyperemesis. Had to go to hospital, get fluids, multiple meds to make me stop vomiting. That was Thursday. Friday I slept a lot, lingering headache, intermittent nausea, took zofran proactively in the AM. Today I felt a lot better, didn't take any zofran this morning. This evening, the nausea hit me again with bad poops (which also occurred on Thursday/Friday). Zofran and a hot bath kept me from continuing to dry heave. I have not partaken in any cannabis products since Wednesday. I'm fine quitting if this is what will happen when I use anymore. This is miserable. Wednesday night I had food from a new place, I ate chicken, my husband didn't, he has had zero symptoms. I also had a salad on Wednesday. Cyclospora? I'm not sure. I'm just extremely uncomfortable. Any thoughts? Has anyone had similar issues or symptoms lingering days after stopping? Plz help.
