Exhaling (and inhaling) through your nose is bad. Marijuana smoke contains more cancinogenic hydrocarbons than tobacco smoke, and your nose is a much less protected area than your throat. You will get those red lines in your nose that old men get (bursted capillaries) except you will get them much earlier in life.
