Pedrolics the RP or resident permit is for expats and families joining them here in qatar and yes ebverybody has to go through blood tests in order to get the RP.

As many answers before when you try to find some "pot" to smoke you will be in trouble (big one) like it's been said: jail and deportation. And wether you believe it or not jail here it's way different than Jail in your home country. (The worst of thw worst)

Once again here in Qatar there is ZERO TOLERANCE for drugs, regardless those drugs are being used in your country of origin on a "legal" basis.
