Prohibition refers to a halt or stoppage on the production, transport, import and export of alcohol and other alcoholic beverages. The term also implies the specific duration in the history of countries during which prohibition of alcohol was enforced. Prohibition was enforced more strictly in Islamic countries since consumption of liquor and intoxicating drinks is considered as a sin in Islamic countries. Prohibition is necessary to keep alcohol consumption and alcohol consumers in check or restrain. Drug prohibition means a ban on the consumption, use, manufacture and sales of drugs. In the words of Michael Badnarik, “Drug prohibition has caused gang warfare and other violent crimes by raising the prices of drugs so much that vicious criminals enter the market to make astronomical profits, and addicts rob and steal to get money to pay the inflated prices for their drugs.”
