What is the legal status of marijuana use for individuals under 21 years of age?

The legal status of marijuana use for individuals under 21 years of age in Massachusetts is that it is illegal to publicly possess or use marijuana. The state law allows adults aged 21 and over to possess and use marijuana for recreational purposes, but this does not extend to individuals under the legal age.

The restriction is in place to align with public safety and health considerations, particularly for younger individuals. Moreover, while medical marijuana is accessible under specific guidelines, minors would still need to follow stringent regulations, including parental consent and the involvement of a medical professional. Thus, the correct answer reflects the state's commitment to regulating marijuana use and ensuring that it is largely restricted from minors in public settings.
