Black Beauties (also known as Black Birds or Black Bombers) are a combination of Amphetamine (Speed) and Dextroamphetamine (Active salt in Adderall). Pills are typically 20 milligrams. Effects include a mild to moderate euphoria, increased hyperactivity, increased awareness of surroundings, increased intrest in repetitive or normally boring activities, decreased apetite, and decreased ability to sleep. The added dextroamphetamine reduces comedown effects compared to amphetamine alone, but not to the extent of methamphetamine.
