In response to a declaration by the Marijuana Policy Project, National Institute of Drug Abuse released a statement denying that pot is less toxic than alcohol.

Mason Tvert, the director of communication for the Marijuana Policy Project, a national group promoting the legal use of medical and non-medical marijuana, declared that, "Most Americans are recognizing that marijuana is not as harmful as they were led to believe. There's so much evidence out now that any person looking at it objectively would have to call our current marijuana policies into question."

The NIDA retorted, "Claiming that marijuana is less toxic than alcohol cannot be substantiated since each possess their own unique set of risks and consequences for a given individual.”

The denial did not mention statistics reported by the Centers for Disease Control and Prevention’s in 2010, which mentioned that there were 41,682 alcohol-related deaths that year and none from pot.

The denial also did not address Sanjay Gupta’s recent reversal on the subject, in which he stated to CNN, "I have apologized for some of the earlier reporting because I think, you know, we've been terribly and systematically misled in this country for some time. And I did part of that misleading."
