I think it's the weed. I was smoking some weed and after a bowl I couldn't get any higher. Just felt the same but laster longer. Then 2 days later my friend comes over with some DANK I mean so dank he told me to close my eyes and smell the weed, the smell made my head jerk back. 2 hits off that bud and I was more stoned then I ever got with that crappy bud.
