I don't really think it matters. You gotta realize how many people actually smoke trees or used to. Most people don't seem to mind, just the people in power (go figure). I, personally, don't like to smoke openly as I have a criminal record and would probably get fucked in the ass if I got caught on drug charges again. I've smoked joints in public before, don't like it as much as smoking in a safer environment though such as my room. I don't hide the fact that I smoke though, that'd be pointless.
