Thanks a lot for all the replies, I'm overwhelmed! Yesterday, as an experiment, I did a very short session, 0.3/0.4g maybe, just 5 or six puffs in 20 minutes...and I got a very nice high, not so "high" (almost psychedelic ) as I used to get in my first sessions, but I think maybe that is the way....the high lasted like 3 hours, and was very nice. As I said, I only vape once a week, maybe two (friday and saturday night), and I've got nice highs with my V-Tower Vape and the different strains I've used. Maybe I was trying to get that psychedelic high by using more weed, or vaping harder, and that gets me stoned. My favourite high is when I put a nice music concert (btw, The Cure "Show" is my favourite!!! You guys should give it a try) and can concentrate in the music and images, feeling and hearing each instrument separately and hearing almost in 3D...sometimes I could feel I was literally there, watching the concert live. I'm a music freak, and flowers improve the experience dramatically!!!!
