Legalization
(重定向自Legalisations)
Legalization (also spelled legalisation) is the process of removing a legal prohibition against something which is currently not legal.
Legalization is a process often applied to what are regarded, by those working towards legalization, as victimless crimes, of which one example is the consumption of illegal drugs (see drug legalization).
