Actuosity...glad you have managed to avoid any mental issues. It seems if it's going to be a problem (drug use and mental illness)...it occurs fairly early on. So smoke on!
I forgot to post this little story that occurred 1968. I lived with a group of fellow hippies in a huge old house just south of downtown Minneapolis.
Lots of drug newbies around and it wasn't uncommon for a straight friend to stop by to try marijuana. One guy got totally ripped on some good weed...and according to him, he never came down.
Guy was in bad shape totally stressed by the situation. Wandered around for three days convinced he had gone insane and would be this way for the rest of his life.
We didn't really know what to do...but getting him stoned again was the plan we came up with. Soon as he got high again...he recognised that he hadn't actually been high previously.
My thinking is that he was sensitive to the residual THC in his body and perhaps that felt different enough to cause this problem.
Someone like that may have ended up anxious and depressed and perhaps even with more serious mental illness. But once we got him stoned again...he turned into a pothead just like us...
