Yep
Let me see , I have a Bachelors degree in Electrical engineering , I work for a good pay at a well known multinational IT company. I had lots of desire and motivation the last time I checked.
I smoke weed most weekends , more often than not. I do not smell like cat piss at all , most times I smell like Davidoff Cool Water or have a natural , HUMAN smell , you see, nothing remotely like feline urine.
'Under class' ?
There are obviously exceptions to the rule, it depends on the person, some people can smoke it and still lead a good life, for example one of my best friends smokes 3-4 joints a every night of the week yet is a successful salesman, earning a lot more than any of my other friends but then another of my mates smokes it and has been jobless for over a year, he doesn't seem to have any ambition or drive to better himself. Can't all be blamed on the weed but I'm sure its a contributer.
Personally I've tried it, didn't like it but each to their own. Shouldn't be legalised and almost certainly wont be.
