However, international citizens consume alcohol at home if they have a license. Travelers can do it at qualified resorts, but can't overdo it. And don't ever before think of drink as well as drive, else the effects might be very severe.

Dubai has stringent rules towards drug possession, use, and selling of illegitimate and toxic materials. For that reason, say 'NO TO DRUGS' in Dubai. Some visitors have been kept behind the bars for carrying codeine-based painkillers in their kit.
