My view on drug use has been described as uncompassionate, and I legitimately want to change my perspective, but I haven't been able to. I view drug use as a choice. Yes, there are tons of social, economic, even genetic predisposing factors...but the decision to try drugs or alcohol or smoking or gambling or any other strongly addictive behavior is in the end the user's own choice. It's like it is someone's choice to…
Another: someone with anxiety is prescribed Valium. Over time, it starts to work less well. They go to a doctor, who ups the dose a bit. Repeat, again and again. At no point was the patient ever not prescribed the dose, but addiction happened nonetheless. And when their insurance stops (say, after losing their job), then they need to keep up, and get Valium any way they can.
These are not uncommon. At all. Addiction from other means is typically a result of mental health: someone is desperately trying to fix something, which leads to drinking, which leads… The same is true for any other drug. If you actually interact with addicts, it is very very obvious. There is a reason that AA is the way it is. I really recommend going to a meeting, just to visit. It will absolutely change your mind, if you are open to it.
