Smoking pot is worse than smoking cigs because there is no filter. My friend in college only smoked weed once or twice a month. He went to the doctor for a chest infection and she told him to quit smoking, he replied, "I don't smoke!" and she replied," You're smoking something!" Even though he was a "non-smoker" he had the lungs of a smoker. Admittedly, he did smoke a lot more often in high school but it just shows the damage that can be done to your body.
