Senate Minority Leader Mitch McConnell (R-Ky.) told a constituent in favor of legalizing marijuana that he doesn't support the idea because drugs like pot lead to death.

"Because of the harm that substances like marijuana and other narcotics pose to our society, I have concerns about this legislation. 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," McConnell wrote.
