Considered a healthier alternative to traditional methods of smoking. Vaporizers do just what the name suggests; they create vapor rather than combustion of your smoking material. Vaporizers can be used for dry herbs ,concentrates or essential oils (depending on the style of vaporizer you purchase). Vaporizers are available in many styles, including tabletop vaporizers, vape pens and other portable designs. As mentioned, be sure to purchase a vaporizer that is suitable for the material you will be smoking i.e. flower, concentrate or oil. CLICK HERE to see our full selection of vaporizers.
