@Patricia SteinerSounds like “just say no” to drugs.

Used car salesmen's license (in addition to the actual dealers).

That being said, I believe it would be a great gateway drug into the realm of real estate investing.

Tenants: the best tenants are the ones that have a long term permanent job that already have intense back ground checks, credit checks, drug screenings, and a job that will come down on them if their land lord complains.

I grew up there and it's hard to count how many times NYC's obituary has been written. 60s, 75 bankruptcy, 80s drug wars, 9/11, 2008 crash.
