Hashish, also commonly known as “hash“, is composed of compressed or purified preparations of stalked resin glands, called trichomes, collected from the buds of the female cannabis plant. It contains the same active ingredients—such as thc and other cannabinoids (cbd)—but in higher concentrations than unsifted buds or leaves. The name hashish comes from the Arabic word ( حشيش ) which means grass. The tetrahydrocannabinol (THC) content of hashish comes in wide ranges from almost none to 70%, and that of hash oil from 30–90%.
