in my opinion this conversation has to start with the failure of the war on drugs - thousands and thousands of people locked up or killed, billions and billions of taxpayer dollars spent, and for what? Drugs are easier to get and used more widely these days than they ever have been. Meanwhile our continually escalating approach to policing and incarceration has created continually more ruthless and heavily armed and equipped criminal elements, turned inner cities into gang warzones, and forged some of the most malevolent trafficking organizations in history (and for a bonus, the cartels have completely destabilized and broken the Mexican government and given us an incredibly volatile security threat on our southern border).
there needs to be a complete overhaul of our national drug policy to move towards a more pragmatic and less draconian/Puritan strategy on this stuff. Human beings enjoy using drugs and alcohol - that's just a fact of our history on this planet, and prohibition-based approaches aren't successful in addressing that fact. And the incredible amount of money to be made selling the stuff just leads to more and more desperate, vicious people willing to take the risk, regardless of how rough things get.
I'd be in favor of complete legalization of weed and limited legalization of everything else (basically decriminalization of possession of personal use amounts). Legalized, regulated and taxed marijuana would be a financial windfall for the country, and I don't think the risks (DUI, increased teen use) come anywhere close to outweighing the benefits. I don't think we want to fully legalize hard drugs, although I'm probably a lot more willing to accept arguments for why that might work than most everyone I know, but it's time to stop wasting police resources, locking citizens up, and/or making them pay thousands of dollars in legal fees and live with a permanent criminal record for minor stuff like having a couple of pills or a baggie of cocaine on them. Just take their stuff and flush it down a toilet, give them a misdemeanor citation, and make them attend rehab or counseling. I'd also like to see drastically reduced penalties for nonviolent dealers and suppliers (assuming they're not selling to kids) - save the big prison sentences for violent offenders and try to deincentivize turf wars and gangland killings by going after those guys much, much harder than the ones who are staying peaceful.
our prison system and law enforcement is big business these days, so I'm confident very few current politicians have the balls to propose anything like this, much less actually make anything happen. But in my opinion this one change would be the most effective step we could take to create positive overall changes and alleviate a bunch of problems we're looking at right now with our country in terms of law enforcement reforms, inner city violence, an overburdened judicial system and excessive incarceration rates.
