Each step affects how the oil flows, how stable it is, and how it performs during use.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Distillation<\/h3>\n\n\n\n<p>Many THC oils are refined through distillation, where cannabinoids are isolated and concentrated into a high-potency, uniform base. The process removes most of the plant's original compounds \u2014 terpenes, minor cannabinoids, plant waxes \u2014 which makes the oil easier to control across batches but strips away much of its original complexity.&nbsp;<\/p>\n\n\n\n<p>Most producers reintroduce terpenes after distillation to restore flavor and adjust viscosity, which is why two distillate-based carts can taste and feel very different even at similar THC percentages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Carrier oils and formulation bases<\/h3>\n\n\n\n<p>Once THC oil is refined, it's adjusted based on how it will be used. The formulation looks very different depending on whether the product is meant to be inhaled or ingested.<\/p>\n\n\n\n<p>For tinctures and infused products, carrier oils are used to dilute the extract and make it easier to dose and absorb.<\/p>\n\n\n\n<p>Vape cartridges use a different approach. MCT, coconut, and similar oils aren't formulated for inhalation \u2014 inhaling aerosolized lipids carries real health risks, which is why vape-specific formulations don't include them. Instead, vape oils are balanced with terpenes to control flow and vapor behavior. That balance sets the oil's viscosity, which determines how it performs inside the device.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How viscosity is adjusted for different devices<\/h2>\n\n\n\t\t\t<figure class=\"wp-block-image \">\t\t\t<a href=\"https:\/\/weedmaps.com\/learn\/wp-content\/uploads\/2026\/04\/image-152.png\" data-modal-open=\"lightbox_8410\">\n\t\t\t\t<img decoding=\"async\" src=\"https:\/\/weedmaps.com\/learn\/wp-content\/uploads\/2026\/04\/image-152-768x512.png\" srcset=\"https:\/\/weedmaps.com\/learn\/wp-content\/uploads\/2026\/04\/image-152.png 1024w, https:\/\/weedmaps.com\/learn\/wp-content\/uploads\/2026\/04\/image-152-300x200.png 300w, https:\/\/weedmaps.com\/learn\/wp-content\/uploads\/2026\/04\/image-152-768x512.png 768w\" sizes=\"(min-width: 768px) 476px, (min-width: 1218px) 772px, 100vw\" alt=\"\" title=\"Click to see a larger version of the image\">\n\t\t\t<\/a><\/figure>\t\t\t<div id=\"lightbox_8410\" data-modal data-modal-hide-heading data-modal-manual-close hidden>\n\t\t\t\t<h2>Image lightbox<\/h2>\n\t\t\t\t<img decoding=\"async\" src=\"https:\/\/weedmaps.com\/learn\/wp-content\/uploads\/2026\/04\/image-152-768x512.png\" srcset=\"https:\/\/weedmaps.com\/learn\/wp-content\/uploads\/2026\/04\/image-152.png 1024w, https:\/\/weedmaps.com\/learn\/wp-content\/uploads\/2026\/04\/image-152-300x200.png 300w, https:\/\/weedmaps.com\/learn\/wp-content\/uploads\/2026\/04\/image-152-768x512.png 768w\" sizes=\"100vw\" alt=\"\">\n\t\t\t\t<button role=\"button\" class=\"a11y-modal__close-btn\" data-modal-close-btn>\n\t\t\t\t\t<svg width=\"24\" height=\"24\" viewBox=\"0 0 24 24\" fill=\"currentColor\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M13.414 12l4.293 4.293a1 1 0 01-1.414 1.414L12 13.414l-4.293 4.293a1 1 0 11-1.414-1.414L10.586 12 6.293 7.707a1 1 0 011.414-1.414L12 10.586l4.293-4.293a1 1 0 011.414 1.414L13.414 12z\"\/><\/svg>\n\t\t\t\t<\/button>\n\t\t\t<\/div>\n\n\n<p>Viscosity isn't just about the oil \u2014 it has to work with the hardware.

Oil that moves too quickly floods the chamber, producing light, uneven pulls that don't improve with use.
