Prescription medications can effectively treat health conditions when used properly, but abusing them can lead to serious health risks. Common side effects of misusing prescription drugs include nausea, vomiting, diarrhea, shaking, drowsiness and potential addiction, hospitalization, or death. While most people use prescription drugs responsibly, abuse of medications like opioids, stimulants and tranquilizers has significantly risen in recent decades, especially among teens, with over 2 million young people abusing painkillers by 2000.
