Recreational Marijuana Initiative Position of the MGH/MGHfC

We endorse allowing academic medical centers to study the effects of marijuana and its active constituents and metabolites on medical or psychiatric conditions and/or physical, emotional, behavioral, and cognitive safety in children.

 

We do not endorse the recreational use of marijuana at any age because of the potential downstream effects on children:

  1. The increase in the availability of marijuana and the change in the perception of harm may lead to an earlier-onset and increased rate of marijuana use in children
  2. There are known structural and functional brain changes associated with early-onset marijuana use in children with potential persistent effects into adulthood
  3. Similarly, there are transient and persistent neuropsychological effects of marijuana use in children with persistent effects into adulthood
  4. The addictive potential of marijuana may drive marijuana and other substance use disorders in children. This is of particular concern in that one-half of substance use disorders onset in adolescence; and adolescent-onset substance use disorders predict a more pernicious and longer course of these disorders in adults.
  5. There are well known deleterious effects of marijuana on driving performance, morbidity, and mortality—with specific concerns on the impact on adolescents. Motor vehicle accidents are the second leading cause of death in young people.
  6. An increased availability of marijuana products (e.g. edibles such as candied marijuana derivatives) appears to be fueling marijuana poisonings in children. “All cause” drug related poisonings (including overdoses) are the leading cause of death in young people.
  7. Marijuana concentrates with higher tetrahydrocannibinol levels have been associated with increased risk for short-term anxiety, paranoia, and psychosis; as well as the onset of long term psychotic illness (e.g. schizophrenia) in vulnerable individuals.
