I'm not sure what I think on this topic. I mean, there are plenty of things such as alcohol and cigarettes that are "legal," though still not a good idea to use. Medicines are legal, but you can easily take alittle too much and harm yourself. We certainly can't expect everyone to use it responsibly, but would legalizing it increase the amount of abuse? I would never use it myself, and I don't know anybody who WOULD use it if it was legal. I just know a bunch of people who either use it illegally anyway, or wouldn't at all. Then again, I AM from the south, so I dunno how it differs elsewhere.
As far as the argument of "taxing it and getting more revenue." NO. You get revenue for a good 3 years, tops. It's a freakin' WEED. Anyone can grow it, easy. Legalize it, people pay initially for the seeds, and let it infest their yard. And legalizing weed and then illegalizing the growth of it would be the stupidest thing I've ever heard of lol.
I think there does need to be change, though. They need to either crack down on it and really enforce the law more than they do now, or they need to just give up and legalize it.
