Cannabis sativa, also known as hemp, is a species of Cannabis. It is a dioecious, annual herb. It has been used by humans throughout recorded history for its fiber, for its psychological and physiological potential as a source of drug material, and for the nourishment and oil of its seeds. Different parts of the herb have different uses and different varieties are cultivated in different ways, and harvested at different times, depending on the purpose for which the herb is grown.
Annual herb, usually erect; stems variable, up to 5 m tall, with resinous pubescence, angular, sometimes hollow, especially above the first pairs of true leaves; basal leaves opposite, the upper leaves alternate, stipulate, long petiolate, palmate, with 3-11, rarely single, lanceolate, serrate, acuminate leaflets up to 10 cm long, 1.5 cm broad.
Range and Habitat
It is a native to Central Asia, and long cultivated in Asia, Europe, and China. Plants yielding the drug seem to have been discovered in India, cultivated for medicinal purposes as early as 900 BC. In medieval times it was brought to North Africa where today it is cultivated exclusively for hashish or kif.Native to Central Asia, and long cultivated in Asia, Europe, and China.

Propagation mainly by seed. Seeds stored in cool, dry place remain viable for up to two years. Hemp seed sown as early in spring as possible. Before sowing, land is plowed several times to a depth of about 20-23 cm and repeatedly harrowed the land. In spring the land is harrowed again and rolled, making a firm tilth over the entire surface. In some areas a first plowing is done in the fall and red clover or lupin planted; in January or February a second plowing turns these under as a green-manure. Generally sown in March, seeds germinate at low temperature, but not below 1deg.C. Besides, they are more difficult to handle during harvesting, retting and scutching. Plants require little cultivation, except for weeding during early stages of growth. Hemp grows rapidly and soon crowds out weeds. After plants are 20 cm tall, weeding is abandoned. Hemp tends to exhaust the soil of nutrients. Some nutrients are returned to the soil after plants are harvested. On medium fertile soils a dressing of farm manure or a green-manure crop should be added and turned under. Fiber-producing plants should always have plenty of proper nutrients, especially nitrogen, which is the most important element needed. Irrigation is seldom practiced.
The flowers, leaves and the seeds are the main parts of the marigold which are both of medicinal and commercial importance.
Flowering usually occurs when darkness exceeds eleven hours per day. The flowering cycle can last anywhere between six to twelve weeks, depending on the strain and environmental conditions.
Pests and Diseases
The most common insects that plague marijuana indoors and outdoors are thrips, mites, whiteflies, fungus gnats, budworms, and caterpillars. Of these, mites are most prevalent in indoor grow rooms; outdoor growers generally find that leaf-eating insects like caterpillars and budworms are their most threatening insect pests. The mite feeds on the sap of the plant, mostly underneath cannabis leaves. White specks appear on the upper side of the leaf. After that, you can find spider mites on the undersides of the cannabis leaves, and on the stem of the plant. Spider mites make small webs, which you can detect by spraying with water.

Devotees offered cannabis to Shiva during religious ceremonies, and the herb continues to have a religious association in India. Cannabis was considered a holy herb and was characterized as the "soother of grief," "the sky flyer," and "the poor man's heaven." Centuries later, around 700 B.C., the Assyrian people used the herb they called Qunnabu, for incense. Shortly after 500 B.C. the historian and geographer Herodotus recorded that the peoples known as Scythians used cannabis to produce fine linens. They called the herb kannabis and inhaled the "intoxicating vapor" that resulted when it was burned. By the year 100 B.C. the Chinese were using cannabis to make paper.
It can produce an exhilarating intoxication, with hallucinations, and is widely used in Eastern countries as an intoxicant, hence its names 'leaf of delusion,' 'increaser of pleasure,' 'cementer of friendship,' etc. It is regarded as dangerous to sleep in a field of hemp owing to the aroma of the plants. The famous heretical sect of Mohammedans, who, by murderous attacks upon the Crusaders, struck their hearts with terror, derived their name Hashashin from the drug, and from that our word assassin in derived.
