Smoking causes lung cancer in a minority of smokers.
One should look online for the studies done with cancer and smoking and see how smoking increases the risk of lung cancer and has other risks involved.
Have you ever seen a picture of a guy smoking out of the hole in his neck because he can’t stop? Have you ever seen the terrible pictures of lung cancer and what smoking does to you? Anyone to start smoking now is an idiot. If one already started and is unfortunately addicted, should seek out help and not despair. But to start smoking now-stupidest thing you can do.
