Legal intoxicant

Legal intoxicants, also known as legal drugs or, more commonly, as legal highs, are those intoxicating drugs which are either completely legal or not commonly prohibited by various drug laws. The most widely consumed legal intoxicant is alcohol—legal throughout the vast majority of the world's countries—but a wide array of other drugs are also not specifically banned in many international jurisdictions: these may vary from native intoxicating plants historically used by indigenous cultures to foodstuffs eaten in various parts of the world, to modern compounds and designer drugs that have not been defined as illegal, or even long-standing medicines that have intoxicating or anesthetic side effects. Where legislation imposes a general ban on psychoactive substances (as in Ireland), legal intoxicants are limited to those substances specifically exempted.

Mephedrone a dopaminergic, serotonergic, and adrenergic stimulant. It is legal to possess in some countries.

A mild stimulant found in coffee, tea, and soft drinks, among other sources, caffeine is one of the most widely consumed drugs, noted for its ability to promote wakefulness and provide energy. Caffeine is legal in all countries and jurisdictions, and is in modern times sold in over-the-counter medicines, although historically it was banned (often in the form of coffee) in at least several nations.

Nicotine is a stimulant drug most commonly found in tobacco products. Nicotine and tobacco products are regulated in most countries, and are usually only available for sale to adults: In many developed nations one is required to be 18 or 21—depending on the country—to purchase nicotine or tobacco products. Overall, the age required to purchase cigarettes—the most common tobacco product—ranges from 15 to 21 worldwide. The only nation in which tobacco products are completely banned from sale is Bhutan, and tobacco can only be imported into the country with the consequence of heavy taxation.
