Kindest Regards, Sherry, and welcome to CR!
May I play devil's advocate for a moment?
While I personally agree with you about choice, do you realize that a great many people are of the opinion that their choices are predetermined, even genetic?
It is pretty well evident that the human body was created to react to nicotine. The human body was created to react in an addictive manner to nicotine. If it didn't, the whole cigarette fiasco would be a non-issue. Now, what "we" know is that different people react somewhat differently to nicotine, some are more prone to addiction than others, and some are more responsive to the effects than others. Some are able to walk away from nicotine quite easily, others struggle with an addiction more gripping than heroin.
You said "cigarette companies are responsible for peoples addictions to nicotine because they made the cigarettes." In context you were highlighting the point that cigarette companies did not create the choice to smoke, unless I misunderstood. I agree cigarette companies did not hold a gun to anybody's head and force them to smoke...however:
Cigarette companies have (finally) acknowledged that they did deliberately manipulate the nicotine (and other chemical) levels in cigarettes to make them more addictive. Legal junkies. No, they do not force the first butt into a person's mouth, but they do entice with seductive advertising. And once that first butt is in the mouth, many *are* hooked. Some may take a little longer, but as long as it is socially appealing (sexy gals and red convertibles) more people will continue to try.
The problem isn't so much that cigarettes are addictive, the problem is that they can ruin the typical person's health. Yes, there are the *occasional* stories of 90 year old smokers who have smoked since they were 10. How many can be counted? Compare that number with the countless thousands who have died *prematurely* as a direct result of smoking...I would guess the odds are at least ten thousand to one, probably a lot greater. Pretty high odds to stake a life on.
Actually, as a smoker who is trying to quit, and only been without (this time) for a few months, I am not trying to sell some anti-smoking line either. A person is free to make their own choices...that is where you and I agree.
But the argument "cigarette companies are responsible for peoples addictions to nicotine because they made the cigarettes" actually is true, and doesn't truthfully serve to support your final premise. Cigarette companies did not create the addictive tendency in people, but they did everything they could to exploit it. That's just the nature of business...especially pharmaceutical business (legal and otherwise).
My two cents...
