Methamphetamine physical effects

Systemic effects of methamphetamine are similar to those of cocaine. Inhalation or IV injection results in an intense rush that lasts a few minutes. Methamphetamine has a longer duration of effect than cocaine. Pharmacologic effects include increased wakefulness, increased physical activity, decreased appetite, increased respiration, hyperthermia, euphoria, irritability, insomnia, confusion, tremors, anxiety, paranoia, aggressiveness, convulsions, increased heart rate and blood pressure, stroke, and death. 

Methamphetamine was widely used by soldiers in World War II because its potent stimulant effects kept them awake and alert for longer periods of time and increased their physical endurance. One infamous user of methamphetamine during wartime was one of the most evil men of the twentieth century—Adolf Hitler. Hitler started receiving daily injections of methamphetamine from his personal physician Dr. T. Morrell in 1942, and it was reported he could not function without his daily doses. Hitler also took many other drugs (perhaps over two dozen), including Cola-Dalmann tablets that contained caffeine. Hitler also dispensed methamphetamine to his troops so they could fight for days on end without sleep or food and outlast the endurance of enemy troops. 

CNS stimulants can be classified as Psychomotor stimulants compounds that display a stimulatory effect primarily on brain functions and which activate mental and physical activity of the organism. They are made up of methylxanthines (caffeine, theophylline, pentoxifyllin), amphetamines (dextroamphetamine, methamphetamine), and also methylphenidate and pemoline. Respiratory stimulants or analeptics compounds, which cause certain activations of mental and physical activity of the organism, and primarily excite the vasomotor and respiratory centers of the medulla (doxapram, almitrine).Drwgi that suppress appetite or anorectics drags that activate mental and physical activity of the organism, but primarily accentuate the excitatory center of satiation in the hypothalamus (phentermine, diethylpropion).In order to increase mental capability, nootropics — drugs that increase the functional state of the brain — are sometimes used, the effect of which is associated with blood flow and metabolism of the brain.
