There's not alot of people that haven't smoked weed at least once or just don't give a fuck.
Over the years, I've came to personally know police officers, politicians, businessmen and many other 'outstanding' citizens that smoke weed. So many 'average' parents do it, but keep it private. EVERYONE does it, or doesn't have a problem with it. The only thing that's holding people back is because it's illegal, so people keep quiet to avoid social implications.
It's really not that bad for you either, as long as it's in moderation.
