As the drug cannabis mainly refers to small, multi-branched hashish. The main active ingredient in cannabis is the drug THC (THC). Cannabis drug is divided into three parts: (1), the cannabis plant dry goods: the marijuana plants or plant parts made of pressed after drying, commonly known as marijuana, which is about THC content of about 0.5-5%. (2), cannabis resin: The top portion of the fruits and flowers of marijuana after pressure rubbing oozing resin, also known as cannabis resin, the THC content of about 2-10%. (3) Hemp oil: from the cannabis plant, or hemp seeds, marijuana resin purification of marijuana out of the liquid substance, its THC content of about 10-60%. Cannabis plants A large or long-term use of marijuana, people would cause serious harm to health: (A) a neurological disorder. Overdose can occur confusion, anxiety, depression, hostility human impulses or suicidal wishes. Long-term marijuana can induce psychosis, paranoia and delusions. (2) memory and behavioral damage.

Science knowledge
Cannabis (hemp) common genus Cannabis Hemp seed Sankoh, the scientific name Cannabis sativa L. annual herb, is an ancient bast fiber crops. Hemp fiber white or yellow, shiny, hard and tough, corrosion resistance, suitable for textile coarse and fine linen, manufacture rope, twine and so on. Also manufacture high grade raw material for cigarette paper and banknote paper. Seed oil 30%, 23-25% protein. Hemp oil for human consumption and industrial use. Meals are livestock feed. Seeds can be used as medicine, called hemp seed. Flowers and leaves can be extracted anesthetic. Marijuana mainly in Asia and Europe. Cultivated area and production in China the most, followed by the former Soviet Union. Fiber quality produced in northern Italy for the best. China Shandong Laiwu linen, white linen Yuzhou Hebei and Shanxi Changzhi Lu Ma, in the international market were also known for the quality. Cannabis is dioecious plants. 1:1 ratio of male and female plants in general. Male plant stems slender, small branches; female plant stalk thick and more branches. Root straight roots, mainly in the 20-40cm of soil. Hemp stems straight, high 2.5-5.0m, green, pink and purple are three stem base rounded, angled above the cotyledon node, showing vertical concave grooves, rough skin with short glandular hairs. Fresh stem the rate of 4-6% hemp, hemp dry stems of about 20%. When male and female plants were harvested, dried stalks of hemp rate of 20-25% male plants, female plants is 12-20%. Palmate leaves, the leaflets 3-13 pieces composed. Leaflets lanceolate, serrated leaf margin, petiole length. Male is a complex racemes, female flowers of spikes; anthers yellow a lot of pollen, wind-pollinated flowers. Female flower is not obvious. Pistil of a thin transparent coating sepals, no petals, ovary in a room by a Janus-faced skin structure, stigma filamentous two crack, flowering extends outside the sepals. The fruit is a small oval nuts, ribbed. Peel grayish green, gray or brown, surface tortoises. One seed per fruit, grain weight 9-32g. Marijuana growth process can be divided into three periods, namely the seedling stage, fast growing and mature technology and seed maturity. Cannabis seeds from seed to maturity, the required effective temperature of 2400-3200 ℃. Minimum germination temperature of 1-3 ℃. Surface soil temperatures of more than 8 ℃ planting. Seedlings can tolerate low temperatures and frost of minus 3-5 ℃. Fast growing suitable temperature is 19-23 ℃. Mature seed filling stage is appropriate to the temperature 18-20 ℃. Is a short day plants, early maturing varieties temperature is strong, late-maturing varieties photosensitive stronger. Water demand more. In the fast growing hemp stalks in order to maintain soil moisture 70-80% of the maximum water holding capacity is appropriate. Hemp fiber cell development earlier: fibroblast cylindrical, longitudinal section of fibroblasts mostly vertical lines; circular or polygonal cross-section, rounded corners. Strong hemp fibers in the dry state of 59.6kg / g; the wet state of 36.6kg / g. The main chemical components: cellulose, 65-67%, 14-15% hemicellulose, pectin substances 1.2-1.4%, 4% of the lignin. The main diseases of marijuana are: Cercosporina cannabis marijuana leaf spot, also known as scab, marijuana Sclerotinia Botrytis cinerea, marijuana white spot disease Septoria cannabinus, marijuana downy mildew Pseudoperonosora cannabinus, marijuana blight Phytophthora spp, marijuana leukoplakia Phyllosticta straminella, marijuana. Blight Fusarium spp.. In addition, marijuana root nematode Heterodera marioni, marijuana White Juan disease Corticum centrifugum, marijuana stem blight Phoma berbarum, marijuana and other bacterial diseases Psuedomonas cannabinus. China marijuana pests mainly esserteauiana A, Ma weevils and other beetles and small.

dama Marijuana hemp Marijuana Branch (or Sankoh) is an annual herb marijuana bast fibers. Hemp fiber is one of the world's oldest cultivated crops use. China marijuana precocious, late II. Precocious kinds of high quality fibers, hemp, etc. fall into this category; late-maturing species of coarse fibers, Kui hemp and marijuana Hangzhou fall into this category. Cannabis is native to Asia, ancient in China, Central Asia, the Himalayas and Siberia are utilized around 1500 BC, was introduced to Europe. China in 1800 BC have been used for weaving. Currently the main origin is China, India and the Soviet Union, followed by Turkey, Hungary, Romania, Poland and other countries. 1978 World cannabis production was 310,000 tons. 1980 made in China, 67,500 tons of marijuana, Shandong, Heilongjiang provinces produce most, Anhui, Shanxi, Gansu, Hebei and other provinces are also produced. Because hemp fiber instead of part of production has been declining. Hemp fiber can be used to weave linen, made fishing nets, twine, rope, caulking materials, and paper. About 30% of oil seeds, oil extraction, oil cake is an excellent livestock feed. Cannabis hemp stems dry rate is about 16 to 23% (the rate of female plants of cannabis less). Marijuana is subject unglued after harvest to make the bark and hemp bone separation. Degumming methods are exposed leaching, cold, warm, hot water hemp law, water fermentation method. Summer flooding of 1 to 2 days, 4 to 5 days in autumn, winter 8 to 9 days. Bark made available sulfur smoked bleaching, but also directly to the hemp stalk smoked before stripping system. Hemp fiber quality in male plants as well, female plants is poor, have now been hermaphrodite species, will tend to improve fiber quality. Cannabis single fiber cylindrical tubular tip bifurcation, the surface sections and vertical lines, no distortion, and flax similar. Slightly elliptical cross-sectional shape of the fiber, the cell wall thickness. Usually a single fiber length of 15 to 25 mm, the width is generally 15 to 30 microns. Fiber pale gray with yellow, tough but stiff, poor flexibility, more difficult bleach. Cellulose fiber content of about 77%, the proportion of 1.49, a strong 5.9 to 6.9 g / d. Hemp fiber cross-section of a shape b (Qian Zhang Wu)
