While marijuana can cause some harm if used in extreme amounts or by people who may not react well to it, this is no different than any other substance (i.e. alcohol, tobacco/cigarettes, painkillers, etc) that are perfectly legal in the United States. The law against marijuana is and always has been in place to discriminate against minority groups and target lower-income communities. Since marijuana can actual give users health benefits such as relief from anxiety, epilepsy treatment, etc, there is no reason other than the discriminatory nature of the laws for it to be illegal while other substances remain firmly on legal ground. Marijuana, if legalized, offers the country millions of dollars in tax revenue, limitless health benefits to US residents. Decriminalization also gives those given unnecessarily harsh sentences (considering possession is a nonviolent crime) the chance to become productive members of society rather than sitting in jail for a (typically) victimless crime.
