Answer:
Medical marijuana is increasingly available in the U.S. It is often used to treat chronic pain, muscle spasms, and nausea and vomiting, and to increase appetite. It can affect thinking and memory, increase the risk of accidents, and smoking it may harm the lungs and lead to cancer. Supporters and critics make numerous claims about state‐level marijuana legalizations. Advocates suggest that legalization reduces crime, raises tax revenue, lowers criminal justice expenditures, improves public health, increases traffic safety, and stimulates the economy. Critics argue that legalization spurs marijuana and other drug or alcohol use, increases crime, diminishes traffic safety, harms public health, and lowers teen educational achievement.
Explanation:
In November 2012, Colorado and Washington approved ballot initiatives that legalized marijuana for recreational use under state law.1 Since then, nine additional states (Alaska, Oregon, California, Nevada, Maine, Vermont, Massachusetts, Michigan, and Illinois) plus the District of Columbia have followed suit, either by ballot initiative or legislative action.2 Four additional states approved marijuana legalization in the 2020 November elections (New Jersey, South Dakota, Arizona, and Montana).
