Marijuana is a dangerous and addictive drug that has many consequences to using it. People debate whether it should be legalized or not due to its pros and cons.

The use, sale and possession of cannabis (marijuana) in the United States is illegal under federal law. However, some states have created exemptions for medical cannabis use, as well as decriminalized non-medical cannabis use.n November 2013 Portland became the first city on the East Coast to legalize marijuana as voters passed an ordinance allowing adults to possess small amounts of the drug. Marijuana is still illegal under federal law, and is legal only for medical use under state law.
