Vietnam soldiers who were addicted to heroin were able to stop when they came back because it was a different environment. Addiction is usually caused by circumstancely factors rather than actual chemical imbalances that cause them to seek heroin. Like depression would be the root causing heroin addiction not heroin addiction being the root. This means that when those other things are solved the addiction can usually solve itself so I'd say in a lot of cases a good support system could definitely go a long way to solving an addiction. Albeit I don't agree w her other points
