The pen provides the power, while the cartridge holds cannabis oil.<\/span><\/p>\n<p><img decoding=\"async\" class=\"wp-image-40829 aligncenter\" src=\"https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2026\/01\/lead-in-vape-pens-2-300x200.png\" alt=\"vape pens\" width=\"881\" height=\"587\" srcset=\"https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2026\/01\/lead-in-vape-pens-2-300x200.png 300w, https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2026\/01\/lead-in-vape-pens-2-1024x683.png 1024w, https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2026\/01\/lead-in-vape-pens-2-768x512.png 768w, https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2026\/01\/lead-in-vape-pens-2.png 1200w\" sizes=\"(max-width: 881px) 100vw, 881px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">That brings us to the next component of a vape pen: the oil. Manufacturers fill cannabis vape pens with different types of concentrates, including live resin, distillate, and CO2 oils.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Depending on the type of concentrate in your vape pen, the contents may be as simple as the oil itself. High-quality, full-spectrum vape pens will have lots of natural terpenes preserved in the final product, contributing to a natural, earthy cannabis flavor. Best to opt for live resin, as \u201clive\u201d products are closer to whole-plant products than distillates (basically isolated THC).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">But other extraction methods can erode the terpene content. Many of these pens have cannabis-derived terpenes added back in to maintain the weed-like flavor and aroma. Others may add terpenes derived from other botanical sources to contribute to the flavor profile.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some vape pen oils also include thinning agents for a smoother experience. Ingredients like propylene glycol, vegetable glycerin, polyethylene glycol, and medium-chain triglycerides have all been historically used in different vape pen formulations.
