Two full-page color ads for separate marijuana-related organizations appeared in the front section of The New York Times over the weekend. The ads come one week after the Times editorial board called for the U.S. government to repeal its prohibition of marijuana.

GrassIsNotGreener.com, an affiliate of the nonprofit organization Project SAM, or Smart Approaches to Marijuana, ran an ad in Saturday’s Times calling attention to the dangers of legalizing marijuana.

“The legalization of marijuana means ushering in an entirely new group of corporations whose primary source of revenue is a highly habit-forming product,” according to the ad that drives people to GrassIsNotGreener.com, where the marijuana industry is compared to Big Tobacco.
