Britney Spears recent drug test that she failed showed that the pop star had been taking some kind of amphetamine.

Now an amphetamine Cocaine. Crack. Meth. and a few drugs prescribed for people with major issues are really the only things that show up as amphetamine's. Britney's friends are trying to do some damage control first saying it was Provigil an anti narcoleptic drug or Albuterol, an asthma drug. It has been reported that Britney does not have asthma but she merely uses inhalers as an appetite suppressant.

No matter how you spin it more than likely this is a death blow to Britney's child custody battle.
