So, despite the trillions of dollars, and a hundred years spent on prevention programs and law enforcement and imprisionment and treatment, young people still demand drugs (old people, too; it's just that a young Texan has proposed legalization here).

We could stop the money-drain going into those obviously ineffective programs, and to non-US producers and distributors, create untold hundreds of thousands of new jobs (producing and distributing gauranteed-quality product) by embracing the inevitable, and always growing, demand for mind-altering substances, instead of fighting it.

Take drugs away from the DEA and charge the FDA with establishing growing, processing, manufacturing, distributing, and retailing - drugs. All of 'em. Set standards for production.

At what age do we allow the purchase? 12? 16? 18, surely (if they can vote, and they can kill or die for society, they can intoxicate themselves). 21? 30?

IMO, an intoxicated person should not be able to operate any equipment more complicated than a keyboard, because of the exponential increase of risk to others. So, for me, DWI laws stay in place.
