So how can a 12 step system (which is based primarily on self control) be of any help at all?
Are you referring to someone who is already addicted or the "future addict" that it is inevitable that they will become addicted?
The 12-step system can help them stay alive for one more day. Each day. They will not be cured. They will always need that support, continuous 12-step guidance, and they will almost always remain at a higher risk.
Just say no, right?
In that case "Just say no" cannot be judged as a success.
"just say no" works to say no to the
very first cigarette, drink, or joint. After that first non-self-control of not saying "no" the first time, especially for heroin, it's a huge almost uncontrollable disease. Once they are hooked, the victims choose heroin over their own parents, children, and loved ones, as seen in the adult heroin victim car-deaths with kids in the backseat.
