Which of the following entities is NOT able to get authority to deal with dangerous substances?

Retail customers do not possess the authority to deal with dangerous substances, which often include controlled substances or dangerous drugs. This limitation is primarily due to safety and regulatory concerns aimed at preventing misuse, abuse, and potential harm that could result from uncontrolled access to these substances.

In contrast, practitioners, such as licensed healthcare providers, are granted authority to prescribe and dispense dangerous substances as part of their professional responsibilities to treat patients. Drug jobbers—wholesalers or distributors—also receive the necessary licenses and permits to handle these substances securely and within legal regulations. Manufacturers are involved in producing dangerous substances and must comply with stringent federal and state regulations to ensure safety and efficacy.

The regulatory framework is designed to ensure that only entities with the appropriate training, oversight, and controls have access to dangerous substances, thereby protecting public health and safety.
