Oh yes, it's not your fault. It was the booze, you didn't know any better. Blah blah blah.
If I get ripped, blasted, and then get behind the wheel of a car only to get into an accident taking the life of another; are you to say I am not responsible for that death? We shouldn't prosecute DUI because they were drunk and thus not responsible for their actions? Hogwash
No one forced you to drink, no one forced you to smoke, no one forced you to be ignorant on the subject. Your choice, you did it all. You made the decision to drink, you made the decision to smoke, you made the decision to not educate yourself on the chemicals and drugs you were putting into your body. You got drunk and had a cigarette, but less you are an alcoholic you do not live your life in perpetual drunkenness. Which means, at some point you were sober and at some point you could have looked up the information, and at some point you could decide to stop. Your choice, your fault, your consequences; own up.
I do not defend the tobacco industry, I defend people's right to make choices for themselves. It is a personal choice with real consequences, and those consequences are the individual's to live up to. You want to remove blame, make yourself out to be a victim so you can feel better. But in the end, there is no one else whom controls your brain, no one else controls your nervous system, no one else can make you smoke. You made that choice yourself, grow up and accept responsibility.
