This chapter explores the multitude of divergent information about cannabis that students are regularly exposed to and how these influences inform their beliefs. Pro-marijuana material is often ignored by college professionals, but it is a primary source of information to marijuana-consuming students. This is contrasted with the well-researched but often less-compelling evidence submitted by the government and prevention organizations. The sources of all this material have their own agendas and biases; the trick is in weighing those biases accurately. Readers already influenced by one side or the other can easily dismiss sound data as propaganda or can embrace the latter as fact.
