I don't smoke anything frequently but if someone offers me a cigarette I'll smoke one with them. If by some abomination of brain chemistry I became addicted to nicotine from one cigarette over a month span, I'd buy an e-cig to curb the cravings. You people act like smoking a single cigarette will either directly cancerize your lungs or automatically addict you into forcing you to get cancer. The pictures of smokers' lungs are the outliers of chain smokers, saying you don't want to smoke because you don't want to get cancer is like saying you don't eat because you don't want to get so obese you can't leave your room. A donut isn't going to make you obese, and a cigarette isn't going to give you cancer.
