Dabbing hash oil. The clear quartz bucket has been heated using a torch and the hash rosin placed within (seen melted as the small amber puddle). The glass cap (upper left of frame) is placed on top and creates a low pressure zone in the bucket, allowing the material to vaporize at a lower temperature than the ambient atmosphere. The vapor is then directed through a water pipe to further cool before inhalation.

Hashish (حشيش, ), also known as hash, "dry herb, hay" is a drug made by compressing and processing parts of the cannabis plant, typically focusing on flowering buds (female flowers) containing the most trichomes.

The solvent is then evaporated, or boiled off (purged) leaving behind the desirable resins, called honey oil, "hash oil", or just "oil".

Tetrahydrocannabinolic acid

Tetrahydrocannabinolic acid (THCA, 2-COOH-THC; conjugate base tetrahydrocannabinolate) is a precursor of tetrahydrocannabinol (THC), an active component of cannabis.

THCA is often the majority constituent in cannabis resin concentrates, such as hashish and hash oil, when prepared from high-THC cannabis fresh plant material, frequently comprising between 50% and 90% by weight.
