A vaporizer is a device that vaporizes herbs instead of burning them. The vapor encompasses a more minimal amount of tar and drastically lowers concentrations of gases like carbon monoxide. Some Vaporizers can also be used with e-juices and thick oils. There are some vaporizers that have set temperatures and others where you can manually change the temperature. There is really no recommend temperature for a vaporizer. All vaporizers are different and the herbs or e juice being used vape at different temperatures. It’s really up to the user to test and decide the right temperature for them. When using herbs with personal vaporizers, it is best to use grind up your herbs first before use. Since the cartridges are so small is it best to use fine grinded herbs.
