This is a quick experiment to see how a single vaporisation session using a cannabis flower affects you. It compares your scores before a vaping session to your scores at the end of your session. Vaporization of cannabis flower is a quick-onset method of use. Normally people feel the effects within a few minutes of starting to take the first inhalation. A session can last anywhere from 10 minutes to 30 minutes depending on how many inhalations you decide to take. The session is generally complete when the flower material has turned from green to brown and most of the plant chemicals have been vaporised off.
