Then the chips will fall where they naturally would. Some will mess themselves up with pot alone and others won't. Some will gateway to other drugs that will mess themselves up even worse, and some won't.
Who can do pot every once in a blue moon for decades w/o side effects? Who gets addicted to pot alone? Who does other drugs? I don't know and it ain't my business (I don't do drugs)...except for the gubment taxing me more to pay for other people's welfare. For as long as the gubment does that I have a vested interest in keeping as few people from doing pot or other drugs as possible.
Welfare dependency and excessive use of the drug alcohol are linked, but we rightly don't see that as sufficient justification to ban alcohol. And substance bans have costs of their own: both the direct cost of enforcement, and the giving of a monopoly in the market for that substance to violent criminals, with all the ills that follow.
I remember during whichever legalization campaign locally they promised 1)No harmful effects and 2)They would fund addiction programs.
In hindsight I don't know if they were programs to treat addiction, or cause it.
I'm good with the so-called libertarian approach. You do what you want, you're on your own. Should you end up in a gutter, lay there until you get better, or die. Steal from me to support your habit, prepare to be 'resisted.'
I was 'blessed' to to grow up in a household with two addict parents. It's given me an unfailing BS meter, and I can tell you it's been pegged repeatedly on this thread.
Why would you F#$K with your body or mind like that? Life is an amazing event and ends too soon for most of us. Who has so much IQ they're willing to p!ss it away?
