Vaporizing is not about burning. In a vaporizer, flower is heated to the level just before combustion, which results in much fewer carcinogens in your lungs and in the air. It allows you to inhale pure vapor devoid of the toxins that are present in smoke.
Cannabis appreciation for me begins with a love for the flower. Yes, the cannabinoid (e.g. THC, CBD, CBG, CBN, THCV, etc.) percentages are important but equally important are terpenes (Limonene, Pinene, Myrcene, Beta-caryophyllene, Linalool, etc.).
Terpenes are responsible for the aroma of cannabis and are thought to boost its therapeutic benefit. For example, linalool has a calming effect on the body and is known to reduce anxiety. It is also the main component of lavender essential oil.
Different terpenes volitize at different temperatures so devices that offer precision control temperature settings provide the opportunity to taste the true flavor of the flower and all of its terpene-filled glory. To maximize linalool vapors, one would set the temperature to 388 degrees Fahrenheit.
