People try amphetamines for different reasons.
In Southern California, adolescents mistakenly believe that amphetamines are safe and non-addicting. Amphetamines, caffeine, and other stimulants do not give the user extra energy. When a stimulant wears off the fatigue is intense and depression may set in. Only sleep is able to restore the body's energy supply. At first, the abuser may take the drug casually and infrequently.
