The policy to ban marijuana for everyone is the wrong answer because it clearly doesn't solve the problem of the chronic (ab)user in the first place. The better solution is to redirect the money spent fighting the 'drug war' toward positive things like rehab programs and therapy. You will always have a subset of humans who abuse whatever kind of drugs they can get, you can't stop this. So why punish everyone else who can use drugs in a responsible manner?
Both of those are as bad and in many cases worse than cannabis and yet use/possession of the one is a crime and the others merely tax revenues. (Unless you're underage, then selling to you is the crime.)
I don't see how we can make all drugs legal and just say "Hey, if you want to ruin your life with heroin then go for it" because then we have people being violent, robbing, etc. That is, the cost of enforcing is worth it, in a big way.
But with pot, the cost of enforcement is very high, particularly in people's lives disrupted, for a societal cost that is small. It seems to me, even as a non-user, that there are a great number of people who use at least occasionally, and attempting enforcement is sweeping back the tide.
Basically, when everybody does it, then we have effectively decided that it is a societal norm.
The problem is with the "ruin your life" part, not the "heroin" part. If we really want government to get involved, they should get involved when people's lives are being ruined, not when someone is merely making, distributing, or using a substance.
Weed may ruin your social life and career but booze can literally kill you and people around you.
It still boils down to what rights the government has to legislate something like this based on poor choices of a few individuals.
Besides lets not pretend there's any reason its illegal any more except for pharma, booze, casinos and probably cigarette mfgers
That's probably true, but it's not really relevant. There are downsides to making something illegal, so the question really is whether the harm the pot does is greater than the harm of criminalization.
At this point it's difficult for me to see that balance coming down on the side of prohibition.
