I’ve never had to evict anyone where drugs/alcohol were not involved. This does not mean my problem free tenants aren’t doing drugs. If they are I don’t know. But based on the amount of money I’ve spent, if I had my choice I’d prefer drug free tenants.
Most the folks I know are productive stoners. They get up in the morning, go to work, work hard, cash their paychecks, pay the bills, and are happy to just to smoke a little in the evening while watching TV before bed. I know a couple lazy ass stoners, too. They can't keep a job, cycle through 4 - 6 employers a year, when they are trying to keep a job. It really comes down to the same argument as guns. Marijuana in itself is not dangerous or does not make one lazy. It comes down to the person smoking.
