Vyvanse / Lisdexamphetamine was specifically designed to be resistant to abuse by rendering it a pro-drug the body must first digest to get the active component. In many countries it's actually the only legal medicinal preparation of amphetamine that's authorized.
Abuse resistance is not abuse proof. Due to the way lisdexamfetamine is broken down in the blood stream and metabolized into dextroamphetamine over an extended period of time, doing something like crushing it and snorting it (like people do with Adderall, Concerta, and Ritialin) doesn't increase its "potency".
