Laws about the legal drinking age cover a wide range of issues and behaviours, addressing when and where alcohol can be consumed. The minimum age alcohol can be legally consumed can be different to the age when it can be purchased. These laws vary among different countries, and many laws have exemptions or special circumstances. Most laws apply only to drinking alcohol in a public places, with alcohol consumption in the home being mostly unregulated. Some countries also have different age limits for different types of alcoholic drinks.
And some countries/islands like Jamaica, Morocco, Cuba, Togo, Malaysia, Swaziland and Vietnam - have none!
