Prenatal Exposure To Cannabis Associated to Early Initiation of Use When Teenagers

The prenatal exposure of cannabis products to a developing fetus is shown to be associated to higher rates of early onset of cannabis use as a teen, as well as elevated rates of mood disorders. These were some of the findings released in JAMA Pediatrics on June 26, 2023 from authors Miller, A (

Using data from the ongoing Adolescent Brain Cognitive Development (ABCD) study the authors identified a series of variables associated to the initiation and use of marijuana by those in their early teens, mean age 13.43 years. The majority of which suggest earlier onset of use is associated with a higher odds ratio of potentially adverse outcomes. Earlier onset of use can be influenced by internal (family) and external (social acceptance) factors. Caution should be exercised with cannabis for those who are vulnerable, such pregnant mothers and youth as their brain develops.
