but Bob, at this time, in the here and now, all the knowledge about these products and drugs is freely and readily known and available to all, therefore you would have to posit some new drug or device, which would then have to be marketed by some company in order to have a case that fraud was used. I won't comment on the tobacco issue because it is too personal for you, and perhaps that is one reason why it is hard to be objective. However, the fact is that in today's world there is a large amount of information available on so many things to all adults (and I do differentiate minors) that ignorance is no excuse for making a bad decision. At this point, and such ignorance is willful
I fundamentally agree with most of this, BUT it is still an oversimplification. My main point is that addiction changes things, and you have not commented on this. It makes it much more difficult to correct mistakes. Anyone who starts smoking now, at least as an adult, is incredibly foolish in the face of all the freely available evidence, I totally agree. This was historically not the case though. Tobacco companies knew the truth and denied it for a very long time. In any case, adults in general don't start smoking, kids do - but I digress.
Addiction is force. It makes the sale of addictive products that have overwhelmingly more negative consequences than positive, a predatory thing to do. Even if the person is willing initially, stopping is a big problem. Rational thought and action becomes very difficult. Selling further product to this addicted person is an intiation of force, and I do think I'm being objective about that.
