Marijuana wax resembles honey or butter and goes by the street names: shatter, dabs, budder, and honey oil.  The wax is a highly potent THC concentrate that is 10 to 20 times more potent than typical marijuana. 

The resulting high is much more intense and usage can trigger a loss of consciousness, paranoia, anxiety, panic attacks, hallucinations, a state of psychosis, and even permanent brain damage. 

The wax is preferred amongst users due to concealability, and that it only requires a small amount to use in an e-cigarette/vaporizer creating a smokeless and odorless high.
