Finger hash was my first "concentrate", I used to make it all the time, back before I knew what a good thing it was. I remember getting SO extra high that I fell back into my chair and just melted into the music. Attained a mind and body high that felt like pure magic and heaven! I don't think I've ever been as high since.
I'd love to have access to rub (finger hash) again! I imagine the reason I got SO high was because of my low tolerance back then... but I'd love to attempt getting there again anyhow ; D
