I also put some serious thought into being a cop as well. I just have slightly more liberal views on psychedelic drugs, not so much narcotics though. Those serve no purpose other than "to get fucked up". If people want to explore their psyche, they should be permitted to do so in the safety of their own home. I know people who've gotten drunk and done retarded things, while someone who's ultra stoned is much more likely to raid the fridge then savagely beat someone and raid their asshole.
Marijuana is virtually harmless as well. The worst that really happens is a bit of lung damage and maybe a little bit of grogginess until your body naturally recovers. Most people don't take care of their mind or body anyway though, so who the fuck cares if they smoke? The government just doesn't want to go back on nearly 80 years of vicious lies and deceit. They can't afford to admit anymore humongous slip ups. Furthermore, they make no money off of it either. It's now a BILLION dollar industry in illegal and even LEGAL revenue (bongs, paraphernalia, weed posters and stupid shit like that)... the government gets to tap none of that so they just say "fuck it" and continue with their lies. It pisses me off.
I'm pretty fortunate to have never run into any legal troubles. I've been busted and have had close calls, but nothing more than a minor inconvenience. I feel sad for the people that go to prison too. I know great people who grow small, personal stashes and they're not even half as harmful as marijuana. They couldn't hurt or inflict any sort of damage, pain or inconvenience to a fucking fly, but someone will toss them in the slammer because of archaic laws built on lies, racism and deceit? Total bullshit... even if I made the decision not to smoke anymore I would still be utterly outraged. But ah well, even if I wanted to smoke a pound of grass a day I wouldn't get in shit for it. It's still irritating to think of all the people who's lives have been ruined because of prohibition though.
