As expected, the statements in the ad were true (despite Politifact giving a strange conclusion as to why it was only mostly true). What was unexpected, however, was the response from the National Institute on Drug Abuse:
"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," wrote the institute. NIDA, part of the National Institutes of Health, funds government-backed scientific research and has a stated mission "to lead the nation in bringing the power of science to bear on drug abuse and addiction."
MPP’s Mason Tvert had this to say:
"Our federal government has been exaggerating the harms of marijuana for decades, but at this point it has gone off the deep end," Tvert told The Huffington Post. "NIDA's statement that marijuana can be just as toxic as alcohol would be on par with the FDA announcing sushi is as fattening as fried chicken."
"This is gross negligence on the agency's part and should be addressed immediately by the White House," Tvert continued. "It is one thing for our federal officials to convey their opposition to marijuana policy reform. It is an entirely different and more disturbing situation when they are conveying opposition to scientific evidence."
