Medicine & Other Substances
Any substance you take can change how your body feels or functions. Prescription medicine can be life-saving and help people improve their health. Over-the-counter (OTC) medicine, herbal products (including powders, pills and herbal teas), and vitamin and mineral supplements can also help people maintain and improve their health. Substance use can include the use of legal and illegal substances or prescribed medicine and OTC products not being used as intended. It can be harmful to your health and may lead to substance use disorder.
