Reading and skimming through various threads, I am concerned about my terpenes. From what I read previous to joining this forum, “terpenes are terpenes”. It doesn’t matter if they come naturally from cannabis or fruits (such as lemons). Various users on this forum seem to think otherwise. Not to mention, some members here have mentioned that suppliers such as True Terpenes can be toxic (I.e. their terpenes are turpentine). This has greatly concerned me on many levels. I’m using Harlequin from Terpene Botanicals, which are derived from natural fruits and plants rather than cannibas. The Terpene a-pinene is in there. I don’t want to be vaping TURPENTINE! Any advice or information will be greatly appreciated.
