I hadn't smoked in several years the last time I smoked. It was something called sensamillion, and I had a panic attack that really scared me. I was super-aware of everything. I knew I hadn't really cleaned my apartment for quite some time, and had only been doing surface cleaning. When the high hit, I thought I could smell the dirt in my apartment which so disgusted me that I stayed up ALL night high and cleaning every square inch. Took a lot of trash to the dumpster- in the morning I was tired as heck but the apt. shined like a new penny.

This was not good energy. It was panicked, frantic, jangled up nervous energy and it did not feel good. About half my highs are paranoic and uncomfortable actually. It's like I have too many thoughts to keep up with every little thing that is going on around me and my mind becomes a runaway train. I'm glad the OP asked the question because I thought having panic attacks while smoking was unusual. When it happens it sucks, I can tell you that.
