Amphetamine can be given orally, can be snorted or injected intravenously. Symptoms of use will show up immediately if it is injected, within 3-5 minutes if it is snorted and within 15-20 minutes if it is ingested.
Before amphetamine’s addictive problems were known about, this drug was used for weight control, depression, nasal congestion, even hangovers. It appeared to be an inexpensive, long-lasting solution to a number of problems. It has been sold as Desoxyn, Benzedrine, Adderall, DextroStat and Dexedrine.
