Drugs are another favourite of scam artists. In cities around the Rif Mountains, especially Tetouan and Chefchaouen, you will almost certainly be offered kif (dope). Some dealers will sell you the dope, then turn you in to the police for a cut of the baksheesh you pay to bribe your way out, while others will get you stoned before selling you lawn clippings in plasticine.
Avoid drinking untreated ground water.
