Well in Canada, it's susposed to now be legal to have a small amount for personal use. The worst a cop can do is confiscate your personal stash. Doesn't matter how many times. How much personal? I'm not sure, but IIRC, it's at least as much as the Dell Dude, if not more(several joints).
They only go after grow operations, and when they do get the grow dudes, they probably get much lighter sentences then the US because... this is Canada! And of course we are less fanatical about anti-drugism. I used to be a fan of harsh jail sentences, but after reading some stuff, I went the exact opposite direction.
