States around the country, more than 20 in total, have been legalizing medical marijuana. Recently, CNN's chief medical correspondent Sanjay Gupta reversed his opinion on medical marijuana. While recreational marijuana is controversial, many people agree with Gupta's new stance, and believe that the drug should be legal for medical uses. While the benefits of smoking pot may be overstated by advocates of marijuana legalization, the new legalization will help researchers study the drugs' medicinal uses, and better understand how it impacts the body. Currently only 6% of studies on marijuana analyze its medicinal properties. - Business Insider - Misha Barton pictured
