I Think any drug testing would have to be part of collective bargaining with the players union. Anyone else know for sure?
Also, the steroids and other things may not be banned by the NFL. I don’t know for sure but suspect they never banned them.
This is anecdotal but I affirm it is true. I was close friends with a pro lineman. He was on steroids using a private doctor near by. I asked if he feared side effects and even death from the effects of the steroid shots he was getting. He said “ I want to work— If I dont take steroids , I dont work”. He told me that 100% of the offensive and defensive linemen in the league were on steroids. It is a huge scandal that make Arod and Clements look like diversions from reality.
