Final answer:
The National Academies of Sciences, Engineering, Medicine did not find that marijuana use benefited problems with brain development, chronic respiratory issues, or child development during and after pregnancy related to maternal marijuana use.
Step-by-step explanation:
In 2017, the National Academies of Sciences, Engineering, Medicine reported potential benefits from the use of marijuana in certain health conditions; however, they did not report benefits in all areas. Specifically, marijuana use has not been shown to benefit in problems with brain development, respiratory issues from chronic smoking, and problems with child development during and after pregnancy if a woman smokes marijuana while pregnant. The National Academies' report reflects a more informed perspective on the potential medical uses of marijuana, which contrasts with marijuana's historical image as a dangerous substance. Growing recognition of its potential medicinal uses has influenced some public and legal opinion enough to prompt states to reconsider their positions on legalization, especially in light of disproportionate arrest rates and incarceration costs.
