Breeding (excretion) of cannabises from a human body usually occupies some days. The basic psychotropic component of a hemp - a cannabis a THC - after receipt in blood is exposed at once to influence of hepatic cytochrome P450 and the delta 9 THC (11 IT a THC) is oxidised to primary psychoawake 11 . The further oxidation (under influence ) 11 IT will transform a THC to a final not psychoawake product - 11 holes delta 9 THC 9 acid (THC ). Oxidation goes very fast rates: already later 30 minutes after smoking concentration THC in a blood plasma 11 IT exceeds concentration a THC. However removal oxidised a THC from an organism descends far not quickly: for 72 hours 50 % of the consumed dose, and for 5-7 days - about 90 % leave only. Sensitive methods of analysis (immune and GH/MS) allow to find the oxidised cannabises in urine after some weeks after the use; The standard test (with threshold level of detecting no more than 100 ng/ml) is capable to reveal THC within 1-3 days at incidental and within a week at the chronic use of cannabises.

Bong (from Thai - «a water tube») - the adaptation for smoking of marihuana, an Indochina parentage. In an initial variant represents a bamboo tube in length apprx. 5-7 sm; the inferior part of a tube is closed by a septum, top is open. In the inferior part, at height of 3-5 sm from a bottom, the foramen into which the funneled calyx for marihuana is inserted is made. The smoke aspiration is carried out through the top part. Before smoking in a bong it is recommended to fill in a small amount of water for smoke refrigerating. The western variant of a bong is made of a plastic bottle.

The foramen for a smoke aspiration is burnt from below, a cup for marihuana do of a screw stopper, cutting off top and inserting instead of it the made a hole foil or a pipe net. Advantage of such device consists that it is easy for collecting from improvised stuffs in field conditions. The basic lacks - that bottle plastic and the cigarette foil often used for manufacturing of a bong, at heating excrete the toxics which are extremely hazardous to health.

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.

THC (delta 9 ) - one of the basic cannabises. The delta 8 THC, particulate in a kind and analogues (see ) and acids contains in racemes and hemp leaves, particulate in the form of an isomer.

Reaches the maximum concentration in a blooming period; after blossom dust shunt (at a common hemp) or fertilizations (at ) it will gradually be transformed in . The content a THC in marihuana fluctuates from 0,5 to 15 %, in hashish - from 2 to 10 %. A THC - the first (and for today unique) a cannabis permitted for medical application.

The preparations containing a synthetic THC ( and its analogues), are used in the USA, Canada and the Western Europe for knocking over of by-effects of chemiotherapy at a cancer and for struggle against a syndrome of loss of weight at AIDS. Last researches testify that the given preparation also can be effective at a glaucoma, syndrome , phantom pains and some other diseases which are not giving in to treatment by means of other medical products. However studying of medical properties a THC in many respects restrains what the given cannabis possesses strong psychotropic action? Also is the main psychodelic agent of preparations of a hemp.

In the pure state it can invoke a number of unpleasant by-effects (dizziness, hallucinations, causeless alarm and pavor). In natural preparations negative effects a THC are quenched by other cannabises in this connection their method often gives to the patient pleasure and bears to euphoria. From the point of view of modern medicine, it is extremely undesirable, as can serve as the cause for abuse by a preparation.

Simeon’s hemp - suitable for sowing, should have humidity not above 13 %, normal colour for a kind and shine and whole covers without maculae, damages and fractures. The seed grain of a hemp received as a result of harvesting by a reaper or a combine, usually contains many admixings and has the raised humidity. Therefore after thrashing seeds are subject to pre-cleaning, drying, definitive clearing and sorting. To preliminary clearing apply general purpose grain-cleaning machines ( 10, 20). Drying is effected on covered sheds where seeds scatter a layer in the thickness of 3-10 sm and periodically shovel to avoid self-warming. In crude weather and at the raised humidity of seeds it is recommended to apply grain driers with temperature not above 40-45. Definitive clearing is effected on OS grain cleaners 4,5, 5, etc.; sorting - on a pneumatic picking table (the PROGRAM STATUS WORD 1,5 or 2,5). On sowing qualities hemp seeds share on 3 classes, depending on weediness and germinating capacity (Germinating capacity see it is possible to define by sprouting of 1000 seeds. Seeds with germinating capacity below 75 % are considered as the sub-standard. The important indicator of quality of an inoculum - (mass of 1000 seeds) which should correspond to the parametres provided for the given kind. At hemp cultivars seeds compounds 9-26 g/1000 piece; at its decrease more low 8 g/1000 piece it is possible to draw breeding, that the given kind grows wild or degenerates. At feral forms (including a hemp weedy) seeds fluctuates from 2 to 8 g/1000 pieces According to researches of the Institute of bast crops, among seeds of the same kind large have higher germinating capacity, than small.
