Legalization refers to the process of making something that was previously illegal permissible by law. This often involves changing existing laws or creating new regulations that allow for the legal use, sale, or distribution of a substance or activity. Common examples include the legalization of marijuana in various regions, where it is regulated similarly to alcohol. The legalization process typically includes establishing guidelines to ensure safety, quality, and responsible use. It may also involve taxation and licensing, which can generate revenue for governments. Legalization aims to reduce illegal activities and provide a framework for managing the newly permitted substance or activity.
