Metamphetaminum (Pervitinum)
Metamphetaminum (the screw, Pervitinum, Metamphetaminum a hydrochloride) – a narcotic with a strong promoting effect. Cходен with an amphetamine (Phenaminum), but is more awake and it is toxic. It is introduced, as a rule, intravenously.
The screw – self-made injection solution which to some extent contains iodine-metamfetamin (iodine-Pervitinum), but besides contains still the whole heap of rubbish (the rubbish content depends on components and a preparation mean). As initial components for screw effecting use the medicines containing an ephedrine and its structural analogues.
The basic danger – got at the constant use of the screw the excitatory and mental diseases of a various aetiology. The probability of disease by necrosis of cells head and-or a spinal marrow is possible. As blasts a liver, nephroses and other members. Invokes deficiency of vitamins C, B1, B2, B6, B12.

Mainly, Pervitinum use for stimulation of the central excitatory system. Frequently, Pervitinum prepared from an ephedrine (restoration by means of iodine and phosphorus) introduce with a view of test of narcotic euphoria as its action (presumably, owing to containing admixings) is accompanied by extremely strong sensations. Less often Pervitinum use by means of an aspiration or smoking (such mean of introduction can invoke a necrosis of tissues). In some secs after “a screw” injection (Pervitinum prepared from an ephedrine) there comes the subitaneous beginning of action, very strong and stunning (so-called “arrival”), sometimes accompanied by hallucinations. After introduction there comes extreme mental stimulation within nearby 8 hours then there comes a breakdown, sometimes a depression (so-called “withdrawal”).
In the recreational purposes Pervitinum, in connection with its inaccessibility, synthesise a handicraft mean (as a rule, with utilisation of medicines containing an ephedrine. The matter is that to name the material produced in house conditions, Pervitinum it is not absolutely true. In the course of synthesis the mass of by-products gets to a finished product. Often consumers of handicraft Metamphetaminum (”screw”) it appears in neurology units of hospitals with various disturbances of movements (paresises, disturbances of a gait, etc.). It is supposed that strong euphoric action of such drugs is caused by analogues of Pervitinum, such as iodine-pervitin. Raspostranennoe complication of abuse, a manganous encephalopathy (result ining to a paralysis of the inferior extremities), is identified with presence at a drug of admixings of manganese (one of reagents at manufacturing).
