I do. The aura kinda gets problems no matter what. If you have stress,a negative emotion or go somewhere with negative energy it will get holes in it or some other problem. I know they say smoking can cause cancer but,everything these days does. However,it is terrible on the lungs and if you want to be a singer just forget about smoking because it will kill your voice. I witnessed a girl who use to be very energetic now,cough and not be able to run an inch without being breathless. Everything in moderation. If you must smoke do so only on special occasions. You may also consider getting those electronic cigarettes.
