Positive steroid tests result in a 50-game penalty the first time, a 100-game punishment the second time, and a lifetime ban the third time. Urine testing for anabolic steroids and amphetamines are given at random during the season or offseason. At least once a year, players must be tested. If found positive, they will be punished by suspension. In addition, if a player is suspended for using performance-enhancing drugs, then his team is protected from future sanctions if that player commits no other violations of the substance abuse policy over the remaining life of his contract. The player also has the right to apply for reinstatement after three years have passed. The league's drug policy was revised in 2010. Previously, players who tested positive for steroids received one-year suspensions without pay. From 2010 to 2015, those found guilty of using PEDs were sentenced to up to four months in jail with up to five years' probation. However, under new rules put into effect this past April, players will now receive fines rather than prison sentences. Additionally, it is now possible for players to challenge their suspensions through an arbitration process rather than accepting the imposed penalty. If an agreement cannot be reached, an independent arbitrator will decide the case. Players can be fined up to $25,000 and suspended for four games if they are convicted of a felony drug offense. A second conviction within 10 years leads to a suspension for one full season.
