PULLMAN, Wash. – Teen-age boys exposed to pro-cannabis advertising and social media posts are more likely than female peers to associate marijuana use with improving sexual activity, new research from Washington State University suggests.

Researchers found that the adolescent males expected cannabis users to be less inhibited and enjoy sex more, leading them to express an intention to use marijuana in the future. Adolescent girls and young women, however, were less swayed to future cannabis use by the messages and perceived links.
