The answer is D) Marijuana
Marijuana is the most widely used illegal drug in the United States and the World.
The supply of the drug has created rich cartels of criminals and gangs in Mexico and the larger Central American region.
The wide-spread use of the drug eventually led many States to legalize and regulating its usage to tax and develop a legal industry.
The legalization and regulation of the drug, similar to the regulation of alcohol, will help to curb down on street crime and gangs while ease the pressure on the legal system by promoting healthy and safe uses.
