Drug tourism is travel for the purpose of obtaining or using drugs for personal use that are unavailable or illegal in one's home jurisdiction. Drug tourism can be also defined as the phenomenon by which one's travel experience involves the consumption and usage of drugs that are considered to be illegal or illegitimate in either the visited destination or the tourist's country of origin. This would include crossing a national border to obtain drugs over the counter that are not sold in one's own country, or traveling to another country in order to obtain or use narcotics that are illegal in one's own country, or even traveling from one U.S. state to another in order to buy alcohol or tobacco more easily. Drug tourism to other countries is also popular among college students in the United States younger than 21 who are not yet of the legal drinking age for alcohol purchasing and consumption.
