Hashish is a potent form of cannabis (marijuana) produced by collecting and compressing trichomes, the most potent material from cannabis plants.
Trichomes are the fine growths on cannabis plants that produce a sticky resin.
Marijuana is a green, brown or gray mixture of dried, shredded leaves, stems, seeds and flowers of the hemp plant Cannabis sativa.
Hashish and hash oil are stronger forms of marijuana.
It is usually smoked as a cigarette (called a joint or a nail) or in a pipe or bong. In recent years, marijuana has appeared in blunts, which are cigars that have been emptied of tobacco and refilled with marijuana, sometimes in combination with another drug, such as crack. Some users also mix marijuana into foods or use it to brew tea.
The main active chemical in marijuana is THC (delta-9-tetrahydrocannabinol). Marijuana’s effects on the user depend on the strength or potency of the THC it contains. Hashish contains the same active ingredients as marijuana, like THC and other cannabinoids, but with higher concentrations.
THC has been used to treat wasting syndrome in AIDS patients.
