The narcotic properties of hemp become concentrated in a resinous juice, which in certain seasons and in tropical countries exudes, and concretes on the leaves, slender stems, and flowers. This constitutes the base of all the hemp preparations, to which all the powers of the drug are attributable. In Central India, the hemp resin called _churrus_, is collected during the hot season in the following manner. Men clad in leathern dresses run through the hemp fields, brushing through the plants with all possible violence; the soft resin adheres to the leather, and is subsequently scraped off and kneaded into balls, which sell at from five to six rupees the seer, or about five or six shillings per pound. A still finer kind, the _momeca_ or waxen churrus, is collected by the hand in Nepaul, and sells for nearly double the price of the ordinary kind. Dr. McKinnon says—“In Nepaul, the leathern attire is dispensed with, and the resin is collected on the skin of naked coolies.” In Persia the churrus is obtained by pressing the resinous plant on coarse cloths, and then scraping it from these and melting it in a pot with a little warm water. Mirza considers the churrus of Herat the most powerful of all the varieties of the drug. The hemp resin, when pure, is of a blackish grey colour, with a fragrant narcotic odour, and a slightly warm, bitterish, acrid taste. The dried hemp plant which has flowered, and from which the resin has been removed, is called in India _gunjeh_. It sells at from twelve annas to a rupee the seer, or from ninepence to a shilling per pound, in the Calcutta bazaars. It is sold chiefly for smoking, in bundles two feet long and three inches in diameter, containing twenty-four plants. The colour is dusky green, the odour agreeably narcotic, the whole plant resinous and adhesive to the touch. The larger leaves and capsules without the stalks, are called _Bang_, _Subjee_, or _Sidhee_ in India, and have been brought into the London market under the name of _Guaza_. They are used for making an intoxicating drink, for smoking, and in the conserve called _Majoon_. Bang is cheaper than Gunjeh, and though less powerful, is sold at so low a price that for one halfpenny enough can be purchased to intoxicate an habituated person. The Gunjeh consumed in Bengal comes chiefly from Mirzapore and Ghazeepur, being extensively cultivated near Gwalior and in Tirhoot. The natives cut the plant when in flower, allow it to dry for three days, and then lay it in bundles averaging two pounds each which are distributed to the licensed dealers. The best kinds are brought from Gwalior and Bhurtpore, and it is cultivated of good quality in gardens around Calcutta.
