Substance abuse with prescription drugs refers to the misuse or abuse of prescription medications, such as painkillers, sedatives, or stimulants. This can include taking medication in a way that is not prescribed, taking someone else’s medication, or taking medication for non-medical reasons. Misuse of prescription drugs can lead to addiction, physical and psychological dependence, and a range of health problems. It is important to always follow the instructions of a healthcare provider when taking prescription medication and to never share or sell medication with others.
