Smoking weed is the most common way to enjoy cannabis, but there is a better way to inhale — vaping. Vaping and heat-not-burn devices avoid some of the issues related to smoking, such as carcinogens created by combustion. Additionally, vapes are more efficient. A California NORML study revealed that vaporizers could deliver 46% of the THC in a cannabis sample. A joint of cannabis delivers only around 25% of the THC. The rest is lost to destruction by heat and side-stream smoke.
