Can't figure out what you're talking about. What kind of addon are you talking about? Do you want to make money while people suffer from addiction? Please be aware that those who use drugs are addicted and suffer a lot from this. My BFF lost a lot of memorable moments just because of this addiction. We fought a lot to handle this situation. Only with the help of professionally trained personnel and a special detox program https://fherehab.com/detox/ we managed to get him to understand the importance of not using drugs and that there's a way of living without them. It took us a lot to fight his addiction but we managed in the end.
