Mexican drug cartels are responsible for the market in illegal substances in many cities across the United States. Marijuana represents a huge portion of their revenue, and its legalization would reduce drug prices nationwide. Former federal agent Terry Nelson said drug cartels “can't transport that much cannabis.” This is evidenced by the fact that marijuana accounts for up to forty percent of drug cartels' revenue from drugs. Further legalization efforts leading to a nationwide legal drug status would mean that cartels would no longer smuggle as much as they did in the past (O'Hara, 2014). Drug cartels receiving less revenue would be a win for the United States. There would be less marijuana-related smuggling across the U.S. border with Mexico. Fewer drug arrests also in the south of the country. An important part of American society is public financing in some sectors. Marijuana would increase tax revenues that would go to public services and institutions such as schools and hospitals. Marijuana boosts business in legalized states. Tourism increases in the state due to foreigners trying to get there to participate in some of the activities. Tourism would probably double due to drug legalization. More people wish they could find a place to buy it legally. Denver, the state capital of Colorado, has seen an increase in foreign visitors compared to previous years.
