its really no hassle to find weed there the people are very friendly and really apreciate it if you try to speak thier languge. and you can haggle a little with most of the dealers .. the cops wont even look at you in that part of mexico unless you are seriuosly fucking up like fighting or pissing in public or stealing there is a kick ass flea market on the mainland north of cozumel im sure you can find any thing you want there
