Cigarettes

   Not exactly "black spots", but a good cardiologist will see that you smoke. Don't worry - seek help to quit smoking !!!

   You still have milk in your mouth, you started smoking. Amy may find, you thought. M23

   My grandfather is a doctor and he will take my picture !!! And he really hates cigarettes? The author

   Don't listen to the nonsense of people who have no contact with medicine. On the subject, if you smoke for 2-3 months, nothing will appear in the photo even more "black spots". These tar deposits have been present in smokers for years. I will not teach you to stop smoking, because it is meaningless, after all, I once was your age and I smoked and I know that everyone has to go through this. From a doctor

   Hahaha, when you're 12-16, you start smoking to pretend to be a jerk with mom and dad's money, but then when you start messing around, you realize that it's a nasty habit that costs you 200, that even and BGN 300 per month. Keep up the good work. I have tried cigarettes, but I have never been a smoker, I have been in the field of cigarette advertising and no one smokes King and Karelia for 5 leva, the Bulgarian smokes Sobranie, Parliament and Dunhill, which are over 6 leva a box, the parliament is 7 Otherwise, they complain that they have no money. Expensive cigarettes are smoked even by people who buy for 600-700 leva. This is over BGN 2,500 per year! I don't drive a Porsche Cayenne for the money saved from cigarettes, but when I upload photos on Facebook of how I was in London, Geneva, Stockholm, etc., my acquaintances do not stop envying how I traveled around Europe, where so much money came from. Well, I don't smoke cigarettes like I have. And you, if you weren't busy hiding in the gardens to smoke, but were reading your biology lessons, you would know that "spots" occur after years of smoking! F21
