You have probably seen news reports of the death of Matthew Perry (he played Chandler Bing in the sitcom Friends) He was discovered unresponsive in his hot-tub, and was found to be dead on arrival at hospital. The cause of death was not obvious at first, so Twitter was alive with rumours, including some very nasty posts saying that he, and all the Friends cast, had "sold their souls to the devil" and were drug addicts, so it served him right.
After more tests, it was announced that he had drowned, as a result of the effects of the ketamine medication he was taking instead of the drugs he was trying to escape.

Apparently he was prescribed strong medication years earlier for the extreme pain he suffered after an accident. The medication dosage didn't get rid of the pain, so he sought more of it on the street and became addicted. Since then he had fought the addiction, and helped many people in the same position.
If someone offers you "their pills" to deal with your medical problem, they could be a perfectly legitimate medical drug that is Ok for THEM to take under supervision, but not OK for YOU to take for a different condition with no medical advice. You can become addicted without ever knowing that you are taking a banned substance Ask them what is in the pills, and look them up online before taking them- you will find out the ingredients and the possible side effects.
