I love going off into the woods smoking a fat spliff to myself. Drinking a bottle of water. Sitting on some rocks in the middle of this river. Cleaning my hands in it. Putting on my ridiculous sunglasses and closing my eyes. Than proceding to 'Ohm' my way back into myself than into a trance!
If the weather is right I'm gonna do it tomorrow!
I think Cannabis can clutter the mind, but I know it can help induce the opposite.
IMO: Yes there is a spiritual smoke, but it's not spiritual to everybody. You have to learn to harness it's blessing and not it's "mask"(escape, euphoria). Use it as a sacrament, and it will use you as a sacrament.
