With all the attention on marijuana lately, many parents and teachers are concerned about adolescent use of the drug and its effect on the developing brain. The Colorado Dept. of Education’s Dropout Prevention and Student Engagement Office has created a helpful list of resources on this topic. These resources can help youth make smart choices and understand why marijuana use is still illegal in Colorado for people under 21 years of age. This information can also be useful to parents seeking to talk with their teens about marijuana, and to educators to incorporate into science and health curriculum.
