Mercedes Hash is the resin collected from the flowers of the cannabis plant. The primary active substance is THC (tetrahydrocannabinol) although several other cannabinoids are known to occur.

Mercedes Hash is usually smoked in pipes, water pipes, joints, and hookahs, sometimes mixed with cannabis flowers or tobacco. It can also be eaten.

The most common effects of hash and cannabis are: a sense of wellbeing, relaxation, rapid flow of ideas, increased appreciation of music and food, heightened senses, sleepiness, pain relief, nausea relief and increased appetite.
