Viewing ads for medical marijuana may influence middle school students to use the drug, a new study suggests. Students in sixth through eighth grades who saw ads for medical marijuana were twice as likely as others to have used the drug or to say they intended to use it in the future, the study found.
The study included more than 8,200 middle school students in Southern California,HealthDay reports. In the first year of the study, 22 percent of the students said they had seen at least one medical marijuana ad in the past three months. The following year, the number rose to 30 percent.
