Good post King. Marijuana (and other drugs) can give you temporary access to other states of being. If you like those states, you can learn to consciously access them to induce a more permanent change. For me, that's been one of the major benefits of getting high:
the experiencing of altered states that have aspects I want to consciously induce. Obviously I don't want to continuously have short term memory loss

, but I do like feeling happy and seeing the funny side of everything

. Once you get a glimpse of a better state of being, all it takes is conscious practice to make it permanent.
