Healthcare professionals, including medical assistants, have a special responsibility to prevent the misuse or abuse of legal or illegal drugs. They should educate their patients about the risks and dangers of drug abuse and addiction. They should also monitor their patients for signs of addiction or misuse of prescription drugs. If a healthcare professional suspects that a patient is misusing or abusing drugs, they should report it to the appropriate authorities and provide the patient with resources for treatment and support. Additionally, healthcare professionals should follow all laws and regulations related to the prescribing and dispensing of controlled substances.
