Does marijuana use lead to the use of other drugs?

While most marijuana smokers do not go on to use other illegal drugs, long-term studies of high school students show that few young people use other illegal drugs without first using marijuana. Using marijuana puts people in contact with people who are users and sellers of other drugs and are more likely to be exposed to and urged to try other drugs. Yes, marijuana is a plant but it has very real health consequences, including drug addiction. While some people think marijuana is a “harmless drug,” actual experience and the real science show a different reality. More teens are in treatment with a primary diagnosis of marijuana dependence than for all other illegal drugs combined.
