YEah, I agree with WW about weed. It's not physically addictive but it is mentally. Some people that smoke weed only smoke it on occasion, but I know people who are day-long smokers when they aren't at work. Smoking weed DOES take away one's initiative and motivation. I know 'cause I smoked my fair share back in the 70's! but then I got busy with life (college, work, etc.) and quit. Some people just don't want to I guess. It's not like some addicitve drugs where they physically can't. THe most you get is a headache for a couple of days, kind of like caffeine withdrawal. Whoopedy-doo.
