Premise: Adderall . By salt content , the active ingredients of Adderall are 25 % levoamphetamine salts ( the levorotary or ` left-handed ' enantiomer ) and 75 % dextroamphetamine salts ( the dextrorotary or ` right-handed ' enantiomer ) . The two amphetamine enantiomers that compose Adderall ( i.e. , levoamphetamine and dextroamphetamine ) alleviate the symptoms of ADHD and narcolepsy by increasing the activity of the neurotransmitters norepinephrine and dopamine in the brain , which results from their interactions with trace amine associated receptor 1 ( TAAR1 ) and vesicular monoamine transporter 2 ( VMAT2 ) in neurons . Dextroamphetamine is a more potent stimulant than levoamphetamine , but levoamphetamine has slightly stronger cardiovascular and peripheral effects and a longer elimination half-life ( i.e. , it remains in the body longer ) than dextroamphetamine . The levoamphetamine component of Adderall has been reported to improve the treatment response in some individuals relative to dextroamphetamine alone .
Hypothesis: Adderall does not contain a levoamphetamine component.
