If u smoke weed, and u live n cali, u should get a card. if u dnt, u r taking an unnecessary risk, & those r the 1's that bite u n the ass.
There is no secret list of weed smokers that are going to be rounded up. there are sooo many ppl who smoke, the gov is way more interested in how they can make money on weed than how they can stop ppl from smoking.
as far as roomies growing u hav nothing to worry about...
...unless they lie 2 u about how many plants...
...if they are over the legal limit for their COUNTY, it is a crime, and you'll be compliant to that crime, and you will be part of the investigation. u more than likely wont get jail time, but u'll hav to deal w/the law and probably pay for lawyers.
state law says u can have 6 flowering plants OR 12 vegetative plants PER person. Counties can make their own decisions about if they want to allow patients to grow MORE, but not less.
So as long as u r not flowering more than 6 plants per patient, u guys r legal STATEWIDE
