Can I evict for drug use, now that marijuana is "legal" in CA?

[Daniel Busby]

I've got a 4-plex that my wife and I are owner occupying in Los Angeles.  For a dozen different reasons we want one of our tenants evicted, but of course tenant laws in LA are pretty strong.  However, we have a potential new development that can be a great way to evict them.  The guy came home last night and dropped something while he was opening his door and didn't notice.  I walked up and found a bag of weed.  I had long suspected that they smoked pot in their unit (can't hide that smell) but didn't have any concrete proof.  Their lease is very clear about illegal drugs use being a non-curable offense and cause for eviction.  But, this is California and recently recreational marijuana passed by voter proposition.  Am I still allowed to evict for their drug use, or is that basically nullified now that pot isn't considered illegal in California.  I'm going to reach out to a lawyer of course, but they won't be open until Monday, and I'm dying to know!

it is hard enough to evict when someone does not pay rent in california you going to try to evict because you said you found a bag of weed on the ground ?
