Unless someone stuck you with your first needle, you made a choice. Want to add a addendum for people who were forced into drugs by someone else sticking them? I'll consider it. Everyone else though, knows whats involved and just decided not to heed those warnings.
Nice touch though, likening a drug addict to someone with downs. Clearly, you think very little of the mentally challenged.
Many, many addicts form out of situations that began with prescription drugs (often painkillers). They become addicted long before they realize it, and the nature of an addiction means they won't be able to stop without support (which they won't ask for, because of their nature as an addict). So it escalates to harder drugs.
Are there plenty of addicts that voluntarily took the first step? Yes. But it's definitely not all of them.
And that's not to mention the number of addicts who end up in their position because they came out of situations in which using drugs was a vastly preferable option to dealing with the **** that is their life. And I'm not talking about the hardest stuff first--I'm talking about using the more recreational ones. Like taking hits of acid after you're already drunk at a parties.
Frankly, this is just an excellent example of why it's so hard for addicts to get clean in our society in the first place. People actively incriminate them for being addicts, instead of trying to help them out of their ****.
Not making money doesn't really equate to a drain on society.
I only used the money example because it is what everyone's been fixating on--not wanting to pay the way for someone else.
