Examining science and media literacy health communication messages to reduce intentions to use cannabis while pregnant.

Objective: Although use of cannabis during pregnancy can be detrimental to the fetus, use of cannabis during pregnancy has increased. Pregnant people are often exposed to incorrect information about cannabis use during pregnancy online and have expressed a desire for additional information about the effects of using cannabis while pregnant. We wanted to design and test a brief intervention promoting media literacy and science literacy and assess whether exposure would reduce intentions to use cannabis during pregnancy.
