It might come as a surprise; but there is such a thing as a functional pot user. There are also funcional alcoholics, heroin addicts, prescription users. I've known daily pot users; several: regular cones (aussie bongs)every 3 hours. Mostly tradies, shearers (sheep) and drivers and no one would ever know they are tokers.

Even at Uni I knew one guy who got great grades and who lit up straight after breakfast. I never picked him until I got friends enough with him that he told me. Yeah, his opinions and ideas were a little left of centre, but like the others, perfect motor coordination. I don't even drink coffee so don't think I'm condoning. It's worth knowing though.........
