CBD Wax: Super Efficient

This is a scientific guide.

Based on the latest medical studies.

  • know exactly how much more efficient CBD dab wax is compared to smoking flower
  • see scientific proof dabbing is the most effective way to consume CBD

Let’s get started.

2019 CBD Research

CBD dab wax vs. smoking: 394% more efficient.


nih medical study

New CBD Study Published February 2019

Latest findings: 

  • Dabbing CBD wax, shatter or crumble decarboxylates (activates) 100% of the cannabidiol in the hemp concentrate (1). 

cannabidiol dab concentrates

  • CBD dabs vs. flower: dabbing CBD allows your lungs to absorb 75.5% of the cannabidiol available in the concentrate (wax, rosin, resin, shatter).  Smoking CBD flower only allows the absorption of less than 19-27% of the available CBD in the smoke inhaled (2).

Our summary: The study authors examined cannabidiol concentrates made from BHO (Butane Hash Oil) and supercritical carbon dioxide CBD extraction techniques (3).

cannabidiolic acid decarboxylation

Decarboxylation: The study authors found that the process of consuming CBD concentrates by dabbing (heating to vaporization and then inhaling) caused 100% of the cannabidiol to be decarboxylated.  Decarboxylation is an important part of “activating” CBD so it is bioavailable for absorption.  Decarboxylation occurs as a result of exposing cannabidiolic acid (CBDA) to heat.  Heat causes a chemical reaction in CBDA that changes it into bioavailable cannabidiol (CBD).

Dabbing CBD concentrate for the first time.


What is dabbing CBD concentrate:  The process of consuming cannabidiol by flash vaporization of CBD concentrates on a glowing hot titanium nail.  Vapor is then inhaled through a water pipe (CBD dab rig) or directly in a single puff (4).

Evaluation:  The study authors measured how much CBD was absorbed by the lungs from dabbing CBD wax vs. smoking CBD cigarettes (5).

cannabidiol concentrate


  • lungs absorbed 75.5% of CBD vapor when dabbed.
  • lungs absorbed 19-27% of cannabidiol smoke when consumed as a CBD cigarette.
  • the authors note that considerably less than 19-27% of the total cannabidiol content of the CBD cigarette is actually consumed.  Their study did not take into account the quantity of smoke that is lost from the CBD cigarette between puffs (6).
