What exactly are THC Carts? A THC cartridge is usually a pyrex glass tube that contains concentrated THC oil. The cart takes advantage of a constructed-in atomizer activated by a reusable battery base. The moment activated, the atomizer heats up and vaporizes the THC (or CBD) oil inside the tube. https://judahyjqyf.kylieblog.com/30003776/indicators-on-bulk-carts-thc-you-should-know
