20 Health Benefits of Marijuana
States around the country — more than 20 in total — have legalized medical cannabis. Experts have been changing their minds too — recently, CNN's chief medical correspondent Sanjay Gupta reversed his opinion on medical cannabis.
While recreational pot usage is controversial, many people agree with Gupta's new stance, and believe that the drug should be legal for medical uses.
And even though the benefits of smoking pot may be overstated by advocates of cannabis legalization, new laws will help researchers study the drug's medicinal uses and better understand how it impacts the body.
