Yeah, Having visited and dived Coz for the past 20 years everything changes for the better or worse and Coz in changing for the worse. I started to feel the drug vibe and the pushers in the past 5 years starting to gradually increase... Offering blow, pot, pills and whatever else. If you're into that maybe it seems great but if you're not it is an annoyance.
Note: If you are into that and get pinched in Coz for buying drugs by the police you have put yourself into a hell the likes of which you never imagined. You're a "wealthy" American tourist trapped in the Mexican justice system at that point. I think the Coz tourist police can only hold you for 48 hours before you get shipped to the mainland and parked in a mainland prison (where you certainly don't want to be).
Do as ya will, take the risks but understand the consequences.
A couple of cold SOL beers is all I need at the end of the day.
