From Wikipedia:
Amphetamine is used by some athletes for its psychological and
performance-enhancing effects, such as increased stamina and alertness, but this is prohibited at events regulated by the
World Anti-Doping Agency.
[32][56][18] In healthy people at oral therapeutic doses, amphetamine has been shown to increase physical strength,
[18][57]acceleration,
[18][57] stamina,
[18][58] endurance,
[18][58] and alertness,
[32] while reducing
reaction time.
[18] Like the psychostimulants
methylphenidate and
bupropion, amphetamine increases stamina and endurance in humans primarily through
reuptake inhibition and
effluxion of dopamine in the central nervous system.
[57][58] At much higher doses, amphetamine can induce side effects that impair performance, such as
rhabdomyolysis and
hyperthermia.
Therapeutic doses of amphetamine improve cortical network efficiency, resulting in higher performance on
working memory tests in all individuals.
[19][52] Amphetamine and other ADHD stimulants also improve task
saliency and increase arousal.
[19][53] Stimulants such as amphetamine can improve performance on difficult and boring tasks,
[19][53] and are used by some students as a study and test-taking aid.
[54] Based upon studies of self-reported illicit stimulant use, performance-enhancing use, rather than
abuse as a recreational drug, is the primary reason that students use stimulants.
[55] High amphetamine doses, above the therapeutic range, can interfere with working memory and
cognitive control.

Look, it gives him an advantage. Plain and simple. Did he disclose? Did he really have ADDH or whatever they claim?? Answers that have yet to be disclosed. Fact is, the drug helps a person concentrate better, give them more confidence, etc (it's all up there and on the Wiki site), something that goes hand in hand with TALENT to succeed. I feel it is unfair. Of course it can be broken down and someone could say that better meals, better training methods, better families, more money, etc, gives a person an unfair advantage. Well, maybe, but it isn't breaking any written rules, but what J$7 did was to breaks the rules.
Now I am going to step on some toes here. Some of you that are worried about our sport and the picture it paints. I don't get it. You don't even race in your area-you go chasing races all over the place-anyplace but Ohio as far as I see. SHAME ON YOU. You don't even care about your area racetrack(s). I have no time for your criticism of the sport. No wonder you can't keep vets racing out your way. I'm calling it like I see it guys.
And the ones that think that he is cheating, but should get a slap on the wrist?? I don't get it. He is an ICON to the kids. This sets a terrible example, and if unpunished, shows young people the ends justify, well ANYTHING! I guess examples of a good sportsman isn't worth keeping around.
Hopefully . MX racing in the USA can actually stand up and uphold the rules for once.
All these boards got my blood boiling tonight. I just can't hold it in anymore.
SAD, for sure..........
