A drug test can tell the difference if sent to a lab other wise thetest will show up as just an unknown amphetamine. So if you’regoing to be tested by probation or for court they will tell thedifference because it will be sent to a lab for further testing, asto where a home test (that is not being sent out) or job will notspecify which amphetamine itis.
Specifically, Adderall XR consists of the following amphetaminecompounds in equal proportions: dextroamphetamine saccharate,dextroamphetamine sulfate, racemic amphetamine aspartatemonohydrate, and racemic amphetamine sulfate.
Breakdown rates are affected by many factors including urinary andstomach pH, weight, gender, other medications being taken, and age.Alkalinity increases bioavailability and acidity causes the drug tobe excreted sooner.
Manufacturers claim that the mixture of salts in Adderall XR makesits effects smoother (that is, makes softer highs and lows). Themixture of salts and their ratios are as follows:
1/4 dextroamphetamine saccharate
1/4 dextroamphetamine sulfate
1/4 (racemic dextro/levo-)amphetamine aspartatemonohydrate
1/4 (racemic dextro/levo-)amphetamine sulfate
These four salts are metabolized at different rates and possessdiverse half lives (citation needed), therefore resulting in a lessdramatic onset and termination of therapeutic action, as comparedto single-salt amphetamine preparations (citation needed)
Adderall is available as an instant release (“IR”) as well as anextended release (“XR”) drug
The immediate release formulation is indecated for use in AttentionDeficit Hyperactivity Disorder (ADHD) and narcolepsy, while the XRformulation is approved for use only with ADHD. In the UnitedStates, Adderall is a Schedule II drug under the ControlledSubstance Act due to having significant abuse and addictionpotential.
The difference between the two is this: levomethamphetamine isapproximately 28% of the drug Adderall (racemic amphetamine saltmixture), while 72% of the drug is dextroamphetamine.
