Introduction
Marijuana has long been a controversial issue in the United States. Research has identified that marijuana has the purposes of medical use, and in many states, medical marijuana is promoted by the state government. The very first federal act that is related to marijuana can be traced back to the Marijuana Tax Act of 1937, and the act imposed an excise tax on the sale and possession of marijuana. However, the legalization of marijuana is never an easy act since it involves so many parties. Literature has been developed for years to discuss the potential problems that the legalization of marijuana might face. In many ways, the legalization of marijuana in literature is mainly focused on the possible social change and demographic groups that be affected by further changes. Currently, literature reviews associated with the legalization of marijuana are mainly focusing on social, economic, cultural, as well as political aspects, and are discussing influences to certain groups of the society.
Existing literature usually considers specific demographic groups of users such as youngsters and those who have committed crimes. Current literature always talks about how the legalization of marijuana would affect certain groups but lack of evidence to support the effect on society as a whole. The literature has not been fully established as a solution to the legalization of marijuana since demographic groups in different states have different experiences related to the use of marijuana. Also, existing literature focuses on discussing whether legalizing marijuana contributes to social stability and what might go wrong if certain factors are not fully considered.
