A number of combined risk factors increase the likelihood of abusing drugs in the first place, while reinforcing their continued use. People continue to take drugs to support the intense emotions of well-being released by the brain; this creates a cycle of drug use and intense high. For other people, especially with opioids, drug addiction begins when they take prescription drugs or receive them from other people who have a prescription.
Taking some medications can be particularly risky, especially if you take high doses or combine them with other medications or alcohol.
