If you use Pot, better stop.
If you don't want to be psychotic.
Actually, that does explain some things about people I know who have been heavy pot users. I never was. Smoked maybe 1/2 a dozen cigs back 30 or so years ago. Never did like how it made me feel. I like to be in control of my faculties. I have enough imagination to fly on my own without the help of cannabis.
