Rush does not portray any signs of a "drug problem" or drug abuse.

There is a huge factual difference between addiction and abuse when dealing with prescription pain drugs.

No person can use them for chronic pain without becoming addicted. It is the price you pay for trying to lead a normal life and function at some level without being bed ridden.

Well....apparently JFK (who was also on drugs, and massively) didn't portray "signs" either. There are plenty of examples of alcolohics nad drug users who don't show outward sings.
