Dextroamphetamine (Dexedrine and Dextrostat)
[back] Amphetamines 

See: ADHD drugs  Amphetamines

Dextroamphetamine  is a powerful psychostimulant which produces increased wakefulness, energy and self-confidence in association with decreased fatigue and appetite. It works primarily by inducing the release of the neurotransmitters dopamine and norepinephrine from their storage areas in nerve terminals. Other common names for dextroamphetamine include d-amphetamine, dexamphetamine, (S)-(+)-amphetamine, and brand names such as Dexedrine and Dextrostat.

" Amphetamines:  These are extremely dangerous drugs. They include dextro-amphetamine, Benzedrine, methamphetamine and amphetamine-like compounds such as Ritalin. In general, in high doses, these drugs cause a "body trip" and cessation of thinking activity. In the early days when Dexedrine was first synthesized by Smith, Kline and French in Philadelphia, I did some psychopharmacologic experiments on myself with it. In doses of 150 mgm. there is a spectacular increase in bodily energy and a spectacular decrease in one's critical faculties in regard to this bodily energy. There is a hedonistic over-valuation of one's own bodily acitivity so that repeating tapeloops of bodily movement, for example, can occur for hours at a time. With amphetamines, tank work can become rather repetitious and simpleminded.
     For three or four days after such a trip, there is total exhaustion of the organism. This state can lead to negative things such as trying to get "back to normal" by taking more of the amphetamines. This drives one further into the exhaustion cycle and finally one becomes quite paranoid, quite frightened, and may "freak out" totally. In an attempt to escape the penalty of such tripping, certain persons have taken to barbiturates to calm down the system after the trip. This leads to a cyclical effect in which one gets so depressed by the barbiturates that one takes amphetamines to come up again; one gets so excited by the amphetamines that one takes the barbiturates to go down again. This cyclical "tapeloop" of two drugs can be extremely dangerous—one can   end   up   dead   in   a   hurry.   We   recommend   that amphetamines not be used in tank research."--John Lilly MD (The Deep Self)
