Senate Minority Leader Mitch McConnell (R-KY) recently replied back to one of his constituents to declare that marijuana usage leads to death, according to the Huffington Post.

McConnell sent a response letter to the constituent, who posted it on the pot supporting website Tuesday morning. The Kentucky senator candidly expressed his disagreement and concern over legalizing marijuana in the February 14th letter, citing a medical marijuana bill introduced by Rep. Barney Frank (D-MA) in 2011.

"Because of the harm that substances like marijuana and other narcotics pose to our society, I have concerns about this legislation," McConnell wrote. "The detrimental effects of drugs have been well documented: short-term memory loss, loss of core motor functions, heightened risk of lung disease, and even death."

Despite McConnell's apparent fears, studies have shown throughout the years that marijuana usage does not cause death. Marijuana also is dramatically less harmful than alcohol or smoking cigarettes.
