Would much rather share the road with a pothead than a drinker. Usually if you honk the horn they will realize the stop sign doesn't need to be green for them to go. All in all probably safer than somebody that needs a cigarette and doesn't have one.I personally wouldn't want a pot smoker, legal or illegal, on the road. It is certain some 'legal' smokers abuse the priviledge. If they can legally smoke and drive there is no reason a guy getting off work can't legally open a beer and drink it on his way home.
