I assume you smoked in the bathroom because you knew it wasn't allowed (no matter the substance).

Cash and cash like substance, cost to buy and cost to use, own and control, measuring returns using Stock Market terms and using REI terms, possitive CF and Negative CF, the power of the penny, the power of compounding, goals and plans, etc...4 - You need to learn how to develop a REI Plan.

@Faraad Mohamed You can go through "Islamic" banks but most of their lending is going to be a joke because (A) they source their capital from (mostly) the same sources as other financial intermediaries , (B) calling interest a profit or service fee does not change the underlying substance of the transaction and (C) servicing/interest substitute fees are egregious which often make financing not attractive through these institutions. 

A huge percentage of that is substance issues, mental issues etc. 

It sounds like they would "have the right" to put just anyone in, and I dont have the framework in place to deal with possible behavioral, emotional or substance abuse issues that more qualified environments would offer.
