You have get a supply of drugs for an addict to maintain their habit or for a provider to grow new addicts.
Unfortunately wisdom comes with age and not youth. Therefore I love to see all sources of illegal drugs under attack. Preferable at or outside our borders.
You have get a supply of drugs for an addict to maintain their habit or for a provider to grow new addicts. So? Sounds like capitalism to me. Personally, I don't see any usefulness in preventing any adult who wants to use drugs from using them. Unlike some people, I am fully prepared to accept any and all consequences of living in a free society, where people can get high or outright kill themselves if they choose.
