I really appreciate all the feedback guys. The question really came up because me and a friend were planning on getting a place together and i had my two caregiver cards already. In the mix of finding a place he got his patient card so thats where the issue starts... I personally think the law says we could have 36 flowering plants and 24 seedlings along with 7.5 oz useable in the house, of course these are max amounts and a gram or clone over would be serious problems. But i don't see how if he lives in the house 24/7 (is on call for work) and I work from home 75% there should be TOO much room for trouble. I guess like someone mentioned it all comes down to whether the friend will claim them and hold up on his end of the bargain.

I wouldn't however have his plants at my house and say photocopy his card and put it on the wall. This seems as though it could backfire very quickly. But I have heard of many people doing this

Also the changing of addresses on licenses seems to be a good idea as well. I thank everyone again for the awesome feedback as it seems sad but I really do spend alot of time worrying about this.
