AVENIDA JOSE LUIS CARILLO BEN, San Pedro, AL 29670
As in many places in southern Spain drugs are sold at this beach (mainly Canabis). The drugs sold at San Pedro are of good quality, but quite expensive; they are smuggled from Morocco in the innards, so they may be infectious. Be aware that you can get addicted by these drugs or get a psychosis!
In the summer sometimes thieves come to San Pedro (I have been there about 7 times and never got stolen anything), so don't leave your money unattended!
