A report from the National Academies of Sciences, Engineering, and Medicine – published on 12th January, 2017 – consolidated all evidence published since 1999 regarding the health impacts associated with cannabis and cannabis-derived products, such as marijuana.
In excess of 10,000 scientific abstracts were considered by the committee that carried out the study and wrote the report in order to reach its nearly 100 conclusions.
The growing accessibility of cannabis and acceptance of its use for recreational purposes have raised important public health concerns. Neither the level of therapeutic benefit offered by the drug nor the risks it carries for causing adverse health effects have been rigorously assessed.
“For years the landscape of marijuana use has been rapidly shifting as more and more states are legalizing cannabis for the treatment of medical conditions and recreational use,” said Marie McCormick, chair of the committee; the Sumner and Esther Feldberg Professor of Maternal and Child Health, department of social and behavioral sciences, Harvard T.H. Chan School of Public Health; and professor of pediatrics, Harvard Medical School, Cambridge, Mass.
