Hash, also called hashish, is a drug that is derived from a plant called hemp or cannabis sativa. The active ingredient in marijuana is THC, which is short for delta-9-tetrahydrocannabinol. This chemical and other ingredients are found in the plant’s leaves and flowering parts. Hash is taken from the top of female marijuana plants, where the largest amount of THC is found.
Hash addiction symptoms occur when you use hash in any form on a regular basis. THC builds up in your body fat. It is slowly metabolized in these tissues and turns into inactive metabolites, one of which is THC. Metabolites of THC can be found in the urine for up to 10 weeks after you have stopped using hash. This slow elimination of THC is believed to be the origin of hash’s addictive properties.
