It doesn't sound like you know many people facing these issues. I believe it's unreasonable for you to come to such a generalized position that they don't care to better their lives if offered a helping hand. For example, look at the rise of heroin abuse in the US. A great number of addicts didn't start out going into opium dens and shooting up. Many were taking prescription painkillers under a doctor's care. However, they lost access to that medication at an affordable price for a number of reasons, whether it was a loss of Healthcare, change in their policy, or ham fisted bureaucratic decisions that limits doctors ability to prescribe. (like many top down, across the board solutions, this made matters worse). Without their medication, these people are in a world of pain that I hope you never have to experience. So they turned to what was available and affordable... street opium. They're not running the streets and getting high because they are recalcitrant thugs. They cannot function without the drugs, and they hate that their life has come to that. No one sets out to become a slave of a chemical substance. Effective outreach and ensuing treatment does wonders when it is properly administrated and funded. It also has the effect of signaling to people that individuals and society has empathy for and still values them. This is huge since many addicts have a deep hatred for themselves.
