Marihuana
Marihuana – the Mexican name (a female plant) a hemp of a sowing campaign and its dryed up racemes used for smoking. The tradition of the use of marihuana has been extended in Mexico from XVII century the Mexican immigrants have brought it in the USA.
New intoxicating means quickly has won popularity in the conditions of the dry law: it was cheap and accessible as the hemp was much cultivated in the USA for technical needs. In 1930 years smoking of racemes of a hemp has started to extend among white youth of the USA. The authorities of many states have introduced an interdiction for marihuana, however in conditions when the hemp grew everywhere, no interdictions worked. The exit from this position has been found by the first commissioner of the USA on Harry Anslingerom’s drugs. It managed to push through the Senate the law about «the Tax to marihuana” which has made a hemp growing economically unprofitable. The senators, passing this law, did not see communication between marihuana and a hemp: they voted for the measures confining diffusion of a dangerous drug. As a result hemp sowings in the USA were considerably are reduced, marihuana became less accessible and has risen in price so, that could not compete to alcohol any more. Now “marihuana” officially name the dried racemes of a hemp delivered on «the black market» in whole (see Interestingly, that communication between this product and a hemp plant is obvious till now far not to all. For marihuana manufacturing with dead-ripe racemes or the whole plants suspend the cut off branches headfirst in a shade. At moderate humidity and good air circulation drying usually occupies three four days. The preparation is considered ready when racemes dry up to an elastic consistence: they are easily rumpled by dactyls, but do not crumble. The mass of dried racemes should compound about 14 % of mass of the fresh. The content of psychotropic materials in marihuana reaches 13-15 % (earlier these sizes were much more low: 0,5-11 %). The highest percent a THC contains in – a product from the unfertilized female racemes which have generated false seeds.
Presence in a ready product of a considerable quantity of mature seeds testifies that in it cannabis which psychotropic properties approximately in 10 times are weaker prevails, than at a THC. To store marihuana follows in opaque ware with dense, but an occluded cover; the best variant – tins and faience pots from under tea. In tight packaging marihuana gets a musty odour and easily moulds; in transparent and leaky occluded quickly loses a fortress as the THC cankers under the influence of light and oxygen.
