In many cases, it isn't the level of the THC that affects how "high" you might feel, but the presence of certain terpenes. For example, if the strain you are vaping has a lot of Myrcene, the result is going to be a sleepy feeling; meanwhile if there is a lot of Pinene and Limonene, you are going to feel energetic and focused! As cannabis users become more informed, and research is more available, I predict that terpenes are going to be a much bigger part of the equation when selecting strains, rather than simply THC content.
