In Ca, you have to have a valid doctor's recommendation and the grower has to have a valid doctor's recommendation to obtain our meds from them. It's safest to only obtain meds from a grower who's part of a genuine collective, not just an individual who has the recommendation. If it's an individual, they should probably be a caregiver for you, and that involves more than just growing for you. Stay with the collectives offering meds and be safe. There are a lot of cops who are on that site, looking for violators of Prop 215 and SB420. Watch out. So far I've only seen posts from Sellers not buyers, who have been arrested after answering an ad, or posting an ad, though, so you're probably safe obtaining meds from the site. Just be careful is all I'm saying. Always verify that they have the valid recommendatoin before meeting them, and you should be safe.
