Cannabis Hyperemesis Syndrome; How long until symptoms subside?

Posted by baronvonzutphin @baronvonzutphin, Oct 30, 2025

Hi, everyone. I am a 36 year old male and have been dealing with an extremely aggressive episode of CHS. This past Saturday it took me to the ER because I couldn't keep anything down. I missed some of the signs too. I never really knew about CHS until after my hospital visit. The hospital checked for everything and did all the tests. They didn't look for CHS because I didn't know and perhaps it was their first time as well. The zofran and opioid pain reliever helped and I got checked out the same day. That was five days ago and I am still dry heaving constantly unless I become a merman. It has been seven days since any cannabis product has been used. I must have too much stored in my fat cells to leave me be. I am asking for information but I also wanted to share my story as well to increase awareness. CHS is worse with these new smokeshop alternatives. What I now know to be CHS was much more mild with regular marijuana years ago. Regardless, it is time for me to say goodbye to Cannabis. I am writing this while holding a heating pad to my stomach.

Interested in more discussions like this? Go to the Addiction & Recovery Support Group.

From what I have read and seen with my family member, it can take a while for the pain and stomach to feel better! Thankfully my Family member is now in rehab facility because of his addiction! Going cold turkey and never using again is the answer to a full recovery!

I never had nausea or vomiting, what I do have is the rapid heart beat and very high blood pressure. I only figured it out because continuing use made the symptoms worse.

Unfortunately time will tell. I’m guessing the hospital maybe gave you some IV fluids along with antiemetic medications. There is t much else they do I’m pretty sure. Glad you figured out it was the cannabis because ceasing its use should hopefully end your symptoms. You might eventually be able to use it in another administration method in the future. Sorry this happened. I’m 73 and I’ve been using cannabis in one way or another since I was 16 and never had such a mishap. I hope you feel better soon with the zofran to quell your stomach. Though it appears you didn’t tell the ER you were a heavy pot user?

I was sick with CHS for almost 2 years before I decided to quit smoking and see what happens.. I kid u not, I woke up the next day feeling good and haven’t been sick since! And I was a chronic heaving weed smoker for 20 years.

How did you stop? I’m so embarrassed that I am truly addicted to cannabis. I’m going on two years of hell. I had so much testing they found what they thought was a brain lesion and it ended up just being a growth of blood vessels nothing serious. But first I went through surgery and had an inch of my skull removed. Don’t get me wrong I am thrilled I don’t have brain cancer. But I don’t have the urge to shower because once it starts I can’t stand and honestly feel like I’m in a coma. And I don’t experience much stomach pain.

I wonder if all these side effects are due to the higher levels of THC in the weed and other cannabis products, I know that chronic use escalates pretty much like most drugs, you want the high or buzz but eventually you have to use more to maintain it. I never heard of these side effects years ago because the cannabis wasn't as potent, since it became legal it seems to keep going up in potency, just my thoughts.

Hi frouke,

I'm 71 now and up until a few years ago, had not smoked marijuana since the late 60s, early 70s. That weed was much milder and I could smoke a whole joint and get a nice high and very hungry!

My Dr. prescribed medical marijuana before it was legal in CA to treat anxiety. I was not ready for the dramatically increased THC. First of all, the weed from the 60s and 70s smelled great. These new strains smell foul, like a skunk.

Anyway I had to sit in my chair at home for hours before I could move. I had horrible dry mouth and paranoia.

So no thanks to this new weed (it's actually the bud that is used and contains the most THC).

And I'm pretty sure that in the 60s and 70s we were only smoking the leaves, another reason it was so mild and smelled so good.

No need to be embarrassed by addiction Kathleen. It happens to a lot of us.

I suggest finding a support group for ex-cannabis users. If you can't try one, give an AA meeting a try.

It helps so much to be with others who suffered from addiction and share experiences. You are NOT alone and there is relief in knowing this.

I wish you all the best Kathleen!

@heyjoe415 , You're right about that, in the past the weed was naturally growing with no additives or tampering with the genetics of the plant, people smoked it all the time and I never saw anyone get violently ill unless they started drinking alcohol, the combination was tricky for sure. I have two sons who are grown men with families and I remember learning about the changes with cannabis, and it was getting more potent due to people learning how to to make it so, along came the hydroponic growing operations and this produced the weed you mentioned earlier that has a skunky aroma. I was born in the Netherlands and everyone thought that all we had to offer was cannabis and prostitution, truth is that the Dutch people grew weed for the tourists, they rarely consume it themselves. Lastly along came vaping, big mistake, first they promoted as a healthier alternative to cigarettes and that turned into a huge health disaster permanently damaging lungs faster and then the marijuana industry joined in by marketing ampules to go with vaping but the product is potent sometimes as high as 2,000 mg. I'm sorry for the long rant but it just angers me how our youth are being targeted for profits.
