Who can legally possess cannabis according to the provided regulations?

The regulations surrounding cannabis possession typically outline that individuals must meet certain criteria to be legally considered as possessing cannabis. According to the laws governing cannabis, it is often restricted for certain groups, particularly those in public safety roles, such as firefighters and police officers, along with military personnel.

In many jurisdictions, including Illinois, individuals in these occupations may face restrictions on cannabis use due to the nature of their work, which often requires them to maintain certain levels of fitness, performance, and adherence to drug-free workplace policies. This reflects a broader societal concern about safety, reliability, and the ability to perform essential duties without impairment, which can potentially be impacted by cannabis use.

Therefore, since the question outlines that none of the specified groups (firefighters, police officers, military personnel) can legally possess cannabis according to the provided regulations, the most accurate option is that none of the above can possess it under those specific circumstances. This reinforces the idea that legal possession of cannabis does not extend to individuals whose roles require them to maintain high standards of conduct and compliance with regulations regarding substance use.
