DAB

Dabbing is a method of consuming cannabis that involves quickly vaporizing the extract - called a "dab" - on a hot surface and inhaling the vapor through tubes. Dabbing is popular for its quick and powerful effects, which can often be too intense for beginners. 
There are many different types of dabbable extracts, including BHO, resin, wax and "shatter". They can vary in colour, consistency, potency and texture and are made by different extraction techniques.
Because its effects can be strong, dabbing is the method of cannabis consumption that is most suitable for experienced smokers.
