Dabs—also referred to as wax, shatter, amber, honeycomb, or budder—are concentrated versions of butane hash oil (BHO) which contains highly-concentrated levels of THC. This concentrated substance is produced through a chemical process using butane oil to extract the oils from the cannabis.
Research suggests that dabs or BHO can have a THC concentration of 80% in comparison to traditional cannabis, which has a concentration of about 10-15% THC. In fact, at a minimum dabs are as much as four times as strong as a joint. Plus, people who dab experience an intense high all at once rather than it gradually building over time.
Dabs are made by pouring butane over marijuana. This process allows the THC to leave the marijuana plant and dissolve into the butane leaving a gummy, somewhat solid product that contains high amounts of THC.
