Avogadro has never used any flavor. He sees them at his local smoke and glass shoppe and wonders about them. He agrees that the flowers alone are very tasty. Sour Diesel is his favorite, followed closely by Durban Poison and Trainwreck. He is just curious about the little bottles of flavors and wonders who is using flavors and how the flavor is used. He does not how it is done. Where does one put the flavor drops?
Your local smoke shop has 2 different types of flavors. One for smoking which will not work at all. The other more popular flavor stuff is for e-cigs.
Yes it e-cig juice will add flavor, but it is not meant to cook at the temperatures used for vaporizing herbs. It would be bad for your health. E-Cigs vaporize at a lower temperature than herbs.
However, you can buy this e-cig flavor, and use it with a ball of cotton (and no herbs). Set vaporizer to low temperature and puff away to enjoy flavor. You cannot use it safely with herbs at the same time (and the safety of that e-juice is still unknown, we do not know long-term effects on the human body)
However note that if you vaporize something else (Tobacco, Mint, E-Cig Juice, whatever), your next 1 or 2 sessions in the vaporizer will have some taste leftover. Maybe try vaporizing tea leaves
Many options available, but I suggest you purchase real ground herbs, not the juice!
