Even after doing psychedelics frequently for 5 years or so, I had a trip that landed me in the hospital. Normally, I know to just wait it out, but this time in particular was very bad. It was made worse by the fact that I could no longer think coherently, speak, or understand others, so people I reached out to help for could not help me. That caused me to become completely unmoored from reality and delusional. My one and only time being hospitalized like that. I ended up in some legal trouble because evidently I kicked a first responder when I was out of it. I didn't mean to, but I was thrashing about, apparently. Luckily no real harm was done, but a law is a law (assaulting a first responder is a felony in some states). I'm actually ashamed to admit this to this day, but I think others knowing about it might give them some pause. Since someone may ask, the substance was DPT was administered by IM injection.

The ER doctor said my heart rate had gone close to 200bpm at some points and they had become a bit concerned, so it's probably best I went, anyway. I had PTSD for 6 months after that. I relieved the experience almost every day during that period. It was a very dark and difficult period. So yeah, people who believe there are no bad trips haven't ever had a bad trip like that, I'd wager.

And, you don't need to land in the hospital with concerning symptoms either to have a horrendous trip! I've had two others that gave me PTSD for a time, and I had sober or lightly tripping friends around to help me through those. They were still horrible. I learned some lessons from those experiences (but not good, helpful lessons), and instituted some personal rules that have since prevented any bad trips of that caliber.
