Other data shows that only 4 percent of high schools have some form of drug testing program in place for their football teams.

has tried to distance the policy from being associated with the player, stating that Merriman tested clean on 19 of 20 random tests for performance-enhancing drugs since entering the league. The NFL drug testing season commences on 4/20 of each year (a holiday for the smoking or consumption of marijuana or cannabis.) The NFL is known to take the drug tests seriously. When an athlete is selected for a drug test they must have it completed within 4 hours of notice or else the league will start to impose fines and the possibility of a suspension for not complying. If athletes fail to complete the test in the 4-hour window given the NFLPA (also known as the National Football League Players Association) will still treat it as if they were tested positive (it does not matter if they were clean or not.) The NFL in recent years have drastically changed the testing to these athletes. The drug tests are happening now more than ever before in the league's 100-year history. The NFL in the past 10 years, has begun to crack down on athlete's use trying to catch them off guard in hopes of finding them guilty of using performance-enhancing drugs or (PEDS) for short. Every year the league tries to improve the testing to try to clean up the NFL of all the players. The drug testing season closes when the season closes which means up until Super Bowl week any player can be tested at any time.
Players are notified usually after practice via a note on their chair next to their locker that they are required to complete a drug test. Any failure or refusal to complete the test will be treated as a positive result, and the athlete will be given the full punishment as if they were tested positive. The athletes then have limited time to complete the test to be eligible to play the next week and so forth. The athlete will then urinate into a cup and that will be sent to an official testing facility to deem if the athlete is clean or is tested positive for an illegal substance. After all testing is completed, the athlete and club manager are notified of the results. If the test indicates that the athlete has taken performance enhancing drugs, both individuals are notified of the imposed sanctions. Players can be tested either at a team facility or if the team is away they can be tested at the nearest NFL testing station.


Appeals process

If an athlete is deemed positive for PEDS every player has the option to appeal the result. The most noticeable appeal that has been won in recent years was Richard Sherman in 2012 when he avoided a 4-game suspension because of wrongful practices when he was being tested. Although the likely hood of an appeal going the players way is unlikely. Very few players that are tested positive end up winning the appeal only a few have won the appeal in recent years.


NFL steroid policy

The NFL banned substances policy has been acclaimed by some and criticized by others, but the policy is one of the longest running in professional sports, beginning in 1987. Since the NFL started random, year-round tests and suspending players for banned substances, many more players have been found to be in violation of the policy. By April 2005, 111 NFL players had tested positive for banned substances, and of those 111, the NFL suspended 54. The policy involves all players getting tested times throughout the regular season, the playoffs, and during the off-season. The policy was different in the 1990s than it is today, due to heavy criticism from the

or some other off-season workout, they were suspended for 30 days for a first-time offense. Typically, this would mean missing four games, three in the pre-season and one in the regular season. Players would then be tested throughout the year for performance-enhancing drugs and steroids. A player who tested positively during a previous test might or might not be included in the next random sampling. A player who tested positive again would be suspended for one year, and a suspension for a third offense was never specified, because it never happened. In later years when many players ignored the policy,

by causing the development of male features in the female fetus and female features in the male fetus. In teens anabolic steroids can stunt the growth at an early age due to high hormone levels signaling the body to stop bone growth and can also stunt the growth of teens if the teens use the steroids before their growth spurt. Even though anabolic steroids do not cause the same high as other drugs, they can lead to addiction. Studies have shown that animals will give themselves steroids when they have the chance, just as they do with other addictive drugs. People may continue to use steroids despite going through physical problems, and can cause family issues just like any other addictive drug. These behaviors show steroids' addictive potential. Research has found that some steroid users turn to other drugs, such as opioids, to reduce sleep problems and irritability caused by steroids. People who abuse steroids may go through withdrawal symptoms such as mood swings, fatigue, restlessness, loss of appetite, sleep problems, decrease of sex drive, and steroid cravings.
