Vyvanse is a prodrug developed with an amino acid, l-lysine and dextroamphetamine. The fact that the drug is attached to the amino acid requires the digestive route to active the amphetamine within Vyvanse. Vyvanse was designed to deter abuse and to provide smoother coverage of ADHD symptoms through a day - some studies showing up to 14 hours of symptom relief.

Snorting Vyvanse will not result in a faster onset of actions.
