What are some of the byproducts of marijuana?
Well, there are many other cannabinoids present. They are not present at the same concentrations as either THC or Dranabinol or Cannabidiol, but we really don't know much about those compounds. Like any smoked vegetable matter, there is all kinds of combustion product. There's ash. There is whatever the plant has been treated with or fed with. You have the general set of compounds. You have tar. You don't have nicotine, which differs from cigarettes. But you have the usual set of compounds that come from burning plant material. For that reason, there has been a big push lately to develop vaporization systems that heat the material high enough and rapidly enough, so that psychoactive cannabinoids are released, but there is no burning of the cannabis leaf itself. And so, the amount of noxious particles that are produced is minimized.
