Personally, i'm not one to smoke except for the rare occasion. I certainly don't do it on my own or while playing video games.
However, the ignorance in this topic is mind boggling. Firstly, smoking does not kill brain cells. That would be drinking. Secondly, it is foolish to judge all people who smoke. One of my good friends smokes all the time yet he is probably one of the most genius people i've ever met and is likely to be making six figures his first year out of college. Thirdly, if you've never smoked/drank at all the odds of you being socially awkward and less successful are much higher than if you have.
Gentlemen know that embezzlement, insider trading,tax fraud and similar activities are not actually crimes.Crimes are committed by poor people and involve guns.
