I've came up with a bunch of good ideas while I'm high. I just think of getting money usually. Contrary to what many non-smokers think marijuana motivates me.
Listening to cool music with your eyes closed lets your mind flow. At least for me. haha Also, observing nature in a quiet setting makes me wonder and think of things in different ways. These activities give me a cool mental high when stoned. Try it!
I like to lie in a hot tub with a bowl, candles lit and music playing. I visualize healing going throughout my body. Then the water gets cold, the cd ends, I dropped my lighter in the water and I forgot to get a fu#$king towel! So now I just sit in my easy chair with a bowl, candles lit and music playing visualizing that I'm in a hot tub and healing is going throughout my body. But in reality I have become one with the universe. The chair is trapped by gravity and since I have become one with the chair I am able to stay on earth.
remember different strains will make you want to get up and do something. Others give you a bad case of couch lock. Depending what you are smoking determine different results, but after that it's up to you how you want to enjoy it.
