A vaporizer is a device that heats substances, such as herbs or oils, to a temperature that releases their active compounds in the form of vapor. This process avoids combustion, which can produce harmful byproducts, making it a popular choice for those seeking a healthier alternative to smoking. There are various types of vaporizers, including portable and desktop models. Some are designed specifically for cannabis, while others can be used for essential oils or e-liquids. Vaporizers often come with adjustable temperature settings, allowing users to customize their experience based on personal preferences.
