I think it's ridiculous the way the government regulates what meds we can have in our pockets. I'm no fan of weed, but I'll say this: in the old West, opiates were legal, and not a problem. Why? Because we executed people who couldn't handle it. Turn into a mugger or a robber or a burglar to fund your habit, you got hanged.
I'm all in favor of legalizing weed and getting rid of controlled substances laws IF we can execute those who can't use it responsibly within a year or two of getting a death sentence.
