I had a similar experience when I was young. Bought a vape and some Cannabis, which probably had really high THC concentration as it tends to have nowadays. Took a bit, didn't feel anything, then took a bit more, and boom, a panic attack. Might even had some hallucinations, I'm not fully sure what was real and what wasn't.

After the experience I felt kind of weird and "slow" for several days. Later I found out that there is also a genetic risk of schizophrenia in my family. No way I'm going to touch anything with THC ever again. I've tried CBD oil though and that was okay, slightly calming effect. But ultimately I prefer beer over that too.
