I've smoked lots of pot and know people who have smoked lots of it and from my experience it IS NOT physically addictive but it DOES screw peoples brains up. Cannabis psychosis has been a recognised side effect for years and just because it hasn't effected you YET doesn't mean it doesn't exist. Not everyone is affected admittedy but alot especially with the strong skunk strains that you people smoke these days, when you know people who have jumped out infront of trains or off large buildings maybe your opinion will change until then I recommend backing up your "accademic" study with some hard evidence from some well respected medical journals not peoples opionions on chat forums it looks better in the bibliography!
