I never got a med card, but I've tried a NY MMJ cart from a friend who does have it, it was just ok. Not very impressive. This was also maybe 2 years ago before I knew what dry herb vaping was, so I was even less aware of whats good and whats not. I have no interest in getting a card at this point in time though
No reasoning behind hiding strain names that I can come up with. Maaaaybe because some of the names are ridiculous and certainly don't sound like an official "medication" - but other than that, one can only guess.
