For what length of time does parachuting adderall (dextroamphetamine and racemic amphetamine) last?

Parachuting ? : Adderall (dextroamphetamine and racemic amphetamine) is not a route by which this med, a stimulant (amphetamine salts) is typically prescribed. This medication is controlled, can be addictive, and should be taken exactly as prescribed by ur MD. If by "parachuting" you mean crushing pills and swallowing them, the med will last exactly as long as IR lasts (abt 4 hrs, typically). If you are struggling with addiction, talk to ur MD & get help!
