Are megaconglomerates taking advantage of _____?

I don't doubt they are. This YouTube user is an example: http://www.youtube.com/user/PJsmoker

a) Are tobacco companies/drug lords/lobbyists/et cetera beginning to promote themselves with "real people" having a great/cool time consuming their products?
b) Should I feel guilty for wanting a cigarette after browsing that userpage?
c) Should I quit-smoking-forever/a brief period of time and risk/knowingly go through being uncomfortable for days/weeks/months?
d) Is anyone a "casual smoker"?

How much do you smoke?
