How about pushing tobacco on a corporate scale? Tobacco, some say, is more addictive than heroin. Cigarettes have killed millions of people, yet they are at Walmart. I see them every time I go there. The fact that they are available doesn't mean I will be buying them though. Bleach is available in the laundry aisle, yet I have resisted drinking that. I see bleach and tobacco as both being bad for me, one simply has a quicker affect if administered orally. Both will lead to my death if ingested. Both are off my list as things to imbibe in.
If heroin makes it to the shelf at Walmart, I'll be ignoring that too.
Are you saying if Heroin were more readily available it's use would skyrocket? That's the same argument marijuana prohibitionists use to keep kids "safe" from Marijuana. However in the Netherlands, where Pot is very accessible fewer kids admit to using it than in the United States where there is a "drug war" against it. Why has cigarette use gone down despite it being readily available and legal for adults to purchase?
We could discuss alcohol or corn syrup for that matter as being guilty for ruining lives too, because obviously they do. When a person sells something to a consenting person they are NOT infringing upon their right to make a free choice. If consenting occurs,, it IS an act of free will, even if the outcome is less than desirable to you, me or "society". I do agree that addicts once addicted have very little resistance to refusing a substance. Ask a man in a desert what he will pay for water, alot more than one beside a river would, but I digress. I might take extra water with me though if I knew I were traveling through a desert, but maybe that's just me.
You are saying a persons ability to make wise choices should factor in and some people require babysitting. Who makes that call? That's lead to a prolonged marijuana prohibition, because some people HAVE equated pot to heroin, and they are the same people that make decisions about what will be "criminal substances". When we permit other people to make choices over our bodies they sometimes make errors. Those errors lead to unintended consequences. I'd much rather deal with the unintended consequences of "too much freedom" than too much control. I'd much rather you had the freedom to make an error concerning your OWN body, than a blanket restriction be placed upon everybody because we know a few people will ruin their lives. It is afterall, THEIR life isn't it?
Responsibility over our bodies lies with the individual, to deflect personal responsibility is the same as saying "just doing my job", when the job means arresting people for owning themselves.
I think our differences come down to, I want to be free and I'm willing to let others make their own choices and enjoy or suffer the consequences of those choices. You favor some restrictions. Good luck keeping that genie in the bottle.
