Blew cigarette smoke in drink than drank it before i realized what i did?

Head's up, i'm 19 so i'm of legal age to smoke. People coming here to give lectures, i know it's bad for you, almost every cigarette smoker does. I'm just wondering if it is deadly or anything, i know you can swallow cigarette smoke and that normally doesnt do anything so can blowing it into a drink than drinking it be extremely harmful if you did it once?
