How can a player enter the substance program?

A player can enter the substance program primarily through a positive test result for banned substances. This mechanism serves to ensure that any player who may be violating the league's substance abuse policies is identified and directed toward treatment and support. The positive test acts as a flag that triggers the assessment and intervention process, which is vital for the player's health and the integrity of the game.

Other pathways for entering the substance program exist, such as substance abuse evaluations or referrals from team medical staff. However, the most immediate and definitive route is through a positive test, which immediately indicates that the player may need assistance in addressing substance use issues.
