Normal pot does NOT cause paranoia, by the way. My sister was a daily recreational user in HS and college... finishing with Masters degrees in chemistry and biology and a 3.9 GPA (in the days before high grades were handed out for merely attending class)... and Purdue is not exactly easy on the science majors.
Thank you. I had a 4.0 from an engineering school, many years ago. Any paranoia I felt came because of the government's confused issues about drugs.
