Drug addiction already comes with so many negative side affects that you don't need the added incentive of potentially losing access to housing. If I offered you lifetime room and board in return for a crippling heroin addiction would you take that offer? If not, why not?

Off the top of my head, there are already some fantastic incentives to not be a drug addict such as:

- Massive social stigma and alienation from everyone in your life

- Irreversible mental health issues

- Serious physical health issues (often death)

- The impossibility of doing anything productive or fulfilling
