From Norml:

Self-reported marijuana use by teenagers has declined since 2010, according to annual survey data compiled by the University of Michigan and released today.

Authors state that adolescents’ use of cannabis has fallen slightly since 2010, while respondents’ self-reported use of other drugs, including alcohol and tobacco, are at near-record lows. Young people also reported finding it harder to access cannabis, a trend that has stayed consistent since the mid-1990s.

The conclusions are consistent with other studies — such as those here, here, here, here, here, here, here, here, here, and here — finding that the enactment of state laws permitting the use of marijuana for medical or social purposes is not associated with overall rises in cannabis use by young people.
