Legalization refers to the process of making something that was previously illegal, lawful. This often involves changing laws or regulations to allow for activities that were once prohibited. A common example is the legalization of marijuana, which has occurred in several places, allowing people to use it for recreational or medicinal purposes without facing legal consequences. The debate around legalization often includes discussions about the benefits, such as increased tax revenue and reduced crime rates, as well as potential drawbacks, like public health concerns. Advocates argue that legalization can lead to better regulation and safety, while opponents worry about the implications for society and health.
