Dabbing uses super-potent forms of concentrated cannabis (60-90% THC) -- typically made from hash oil -- and is way too much for the casual pot smoker. Passing out from dabs is a common problem for new users, as the high concentration of THC lowers blood pressure rapidly. Combine that with the mistake of holding the hit in the lungs, and blood flow to the brain drops enough that you can faint. Don't hold in a dab, people.
And remember that, like alcohol, cannabis affects women more profoundly than men. Make sure you only use dabs in safe places with people you trust! There are no known scientific studies of dabs, so we cannot tell you what the best use or long-term effects may be, but some people report more drug abuse potential with dabs. This may be from chemical artifacts left by the extraction method, or it may be the result of the high potency. We don't know! Proceed with extreme caution.
