The traditional "police power" which the 50 states have (in theory), and which the federal gov't does NOT have (in theory), is the power to regulate the "health, safety, welfare, and morality" of its citizens. That's right, the morality even. Taken as a whole, this is a very broad power - not just the health and safety. It's clear to me that if a state wants to ignore the fact the the WOSD is a dismal failure and continue to prosecute it, then by all means they should be allowed to continue it, and have the constitutional power to do so, even to the point of banning the possession of harmless plants. The federal government does NOT have this power under the Constit. That's why the democratic process is so important that it be left TO the states - because, since its so ripe for being overused, that the legislators closest to the people, who are the most responsive to the people, be responsible for its use. And why its so important that the fedgov have NO police power. But now they do, since the commerce clause now extends the police power to the fedgov, virtually unlimited, since Raich (not technically, but practically speaking it does). The ray of hope for states' rights reflected in US v. Lopez was squashed like a bug with Raich. Which is why we're in big trouble vis a vis the health of the Constitution. We can vote out the idgits in state gov'ts, as well as vote with our feet and tax dollars by moving to different states, but the federal gov't is an unstoppable behemoth of political idealogy (the Republicrat uniparty), regardless of who we send to Washington, and cannot be avoided or "voted out" with our feet and tax dollars by moving!
BTW, alcohol is by far the most serious drug problem in our country. Meth is 2nd. Both are extremely devastating; alcohol more so in total, because more people abuse it; meth far more so on a per-user basis - meth comes straight from the devil himself, in terms of (a) its addictiveness, (b) it's negative health consequences to its users, including permanent changes to the brain, and (c) the danger of fire/explosisions/toxic fumes by the makers of it. Neither of these problems in a million years can be whupped by the WOD. Both can be whupped (to a reasonable level) by EDUCATION and TREATMENT dollars, by both private and public budgets, at a fraction of the cost of the current budget of LEOA/Interdiction dollars, and a a fraction of the cost of lost civil liberties. Education to kids and adults alike, but esp. kids, of the negatives of the drug use, and treatment to help people on it break the addiction and once again become productive members of society.
