I'm not saying people find it "necessary" to smoke up, and I'm not against someone wanting to take a toke when they're relaxing. But when I'm partaking, it's more about how I feel, not about my surroundings; I'm focused on myself and state of mind, rather than where I am and what's around me. Perhaps that's more a personal interpretation of what a "power spot" is... One person may find their power spot somewhere that has little aesthetic or physical value, and more emotional value. I, on the other hand, am a very visual person and take my meaningful queues from my surroundings, which I can better appreciate while clean and sober. I can't so much justify focusing on myself when surrounded by visual bliss.
