We (and I don't mean to speak for everyone in your ping but I believe I am in good company) are quite serious about finding a solution. Actually, not so much finding it as it is plain as the nose on our faces, and it is ending prohibition.
The present solution (to drug use in and of itself) employed by much of modern civilization, and to quite an extreme in the U.S., is demonstrably the cause of the most serious drug related problems we face today. The sphere of crime we see that is associated with drugs is almost all the result of drug prohibition.
So, we have correctly identified the problem and do seriously propose the solution.
A nation full of drugged citizens...
There is just nothing to support an assertion such a thing would happen.
The first step is acknowledging that it is a spiritual problem.
Spiritual, morality, whatever you want to call it, some people (good people) do and always will have those failings. But your talk of drugs as magic potions somehow opening a door to the mind for evil spirits is simply asinine.
There is plenty room for persuasive discussion of the biblical principles, keeping the temple clean and so on, but the short term and long term affects of drug use are well studied and documented in science and they are purely medical issues, no more or less than one's poor diet being a contributor to certain disease risk factors. There are criminally insane people who have used drugs, and those who haven't. Likewise, lung cancer patients who smoked or worked in coal mines, or did neither.
Post prohibition, those health issues would remain unchanged, because they have no relationship whatsoever to spirituality, morality, or any law of man. People who are serious about those issues have long recognized that prohibition has done nothing to solve them, and further that it frustrates them in many ways.
Legalization the way you want it will never happen. Just face facts.
The best examples you have are alcohol and cigarettes. You’re talking larger more powerful federal law enforcement to collect the taxes, catch bootleggers, local cops will still arrest underage and public intoxication, etc.
Soon, gardens growing pot will be regulated like swimming pools - inspectors on your property to collect home grown taxes.
Official medical lists of drug abusers, government programs for rehab, children taken from homes due to exposure.
You all aren’t thinking it through. Big brother will get a foot in your front door with legalization.
