I used to do it but not anymore. Well, I suppose smoking weed is essentially meditationg a lot of the time. What I used to do was sit my ass down in a comortable position, close my eyes, and picture some lovely scenery. Basically you o to your happy place. I liked to use my imagination and picture various tranquil scenes unfolding before me. Even tually, you just kind of space out and then come back to it a while later I suppose.
