I brought my trusty cartridge pen with me (from CO2 Company) and used that primarily though I did exchange the pen with others to sample their wares. I prefer to try one strain at a time to assess the overall effects when possible. As I brought my THC cartridge (as opposed to a CBD one I have) and most of what I was gifted was more on the THC side, I had more of an head high versus the overall body buzz I get with CBD.
