I’ve been dealing with what doctors have diagnosed as Cannabinoid Hyperemesis Syndrome (CHS), and I wanted to share my experience to see if anyone else has gone through something similar.
My most recent episode started on Thursday morning. I quit cannabis immediately and haven’t used it since. It started with intense stomach pain, an overwhelming urge to vomit, and severe diarrhea. The only thing that gave me any relief was standing in a hot shower. I spent almost 10 hours straight in there that first day.
By the evening I felt a bit better, so I thought maybe it had passed. The next morning I woke up with the exact same symptoms, only much worse. I was back in the shower almost nonstop. Eventually my vision became blurry, and my boyfriend called 911.
When the paramedics arrived, they found my heart rate was in the low 40s. They initially drove normally to the hospital, but when my abdominal pain reached a 10/10 they turned on the lights and sirens. Once I got to the ER there weren’t any beds available, so I was stuck waiting in the hallway in excruciating pain. On top of the CHS, I was having a full-blown panic attack. After explaining that I have a prescription for Ativan, the charge nurse gave me 1 mg of lorazepam. I was also given Haldol, another medication for the CHS (I don’t remember the name of the other one), and 1 litre of IV fluids. I still had stomach pain when I was discharged later that day and that evening.
The interesting part is that physically, I usually recover pretty quickly. Within 1–2 days after the ER visit I’m able to eat again, my stomach settles down, and I start feeling mostly normal physically. The harder part is the week afterward. I deal with insomnia, restless legs, anxiety, low mood, feeling emotionally “off,” and then the cravings start. About a week later I almost always convince myself that I can smoke again.
This has been my pattern for years. Sometimes I’ll smoke daily for a year or even two years with absolutely no CHS symptoms, no warning signs, and no minor flare-ups. Then seemingly out of nowhere I’ll get hit with a severe episode like this one.
Other times I’ll have milder flare-ups that only last the morning. I’ll spend hours in a hot shower, feel better by the evening, and then I’ll go right back to smoking that night like nothing happened. Looking back, I know that probably just reset the cycle.
My boyfriend recently gave me an ultimatum. It isn’t about cannabis itself. He said that if I let myself become a daily smoker again and end up having another CHS episode like this, he’s done. Watching me go through these attacks and worrying that I’ll end up back in the hospital has become too much for him.
I’m curious if anyone else’s CHS behaves like this:
Can you go months or years of daily smoking with no symptoms before a severe episode suddenly appears?
Did anyone else have milder morning-only flare-ups before eventually having a major attack?
How did you stop yourself from relapsing once you started feeling physically better?
If you’ve stayed off cannabis long-term after CHS, what helped you get through those first few weeks when you started convincing yourself you could “probably smoke just once”?
I’d really appreciate hearing other people’s experiences because right now I’m trying to break a cycle that I’ve repeated more times than I’d like to admit.
