Cannabis

Depressant

Cannabis sativa is a plant found wild in most parts of the world and it is easily cultivated in temperate climates such as the UK. Different forms of cannabis come from different parts of the plant and have different strengths. The plant contains a large number of active compounds collectively known as cannabinoids. The main active cannabinoid ingredient is tetrahydrocannabinol (THC), which is largely responsible for the psychoactive effects of cannabis. It is the most widely used drug of abuse in the UK.

Cannabis is encountered in different forms: herbal cannabis, cannabis resin and cannabis oil. Herbal cannabis consists of the dried flowering tops and leaves of the cannabis plant. Flowering tops from the female plant contain the highest concentration of THC; this is the type of cannabis grown in ‘cannabis factories’ and is typically referred to as ‘skunk’ due to its characteristic pungent aroma. Cannabis resin (sometimes referred to as ‘hashish’) is scraped or rubbed from the dried plant and then pressed into brown/black blocks. Cannabis oil is the least common form of cannabis found in the UK.
