Once upon a time people were told that cigarettes were good for you and smoking was okay. It was pleasurable and calmed the nerves. Surely some of you can remember seeing the old cigarette commercials and people lighting up on TV and in the movies. It seemed like all the big names in Hollywood could be seen with a lit cigarette in their hand or dangling from their lips. FF in time...all of the sudden cigarettes are associated with people dying, so the Surgeon General starts putting warnings on the boxes, cigarette commercials are banned and you rarely see movies where a character smokes. The big names in Hollywood are now getting paid to tell you not to smoke and you rarely see one smoking openly.
The public is constantly being told that smoking is going to kill you, so don't start, and if you have started, quit. That's fine and I seriously doubt that anyone would refute the validity of that. The problem is the general ignorance of some people. They automatically assume that if they see "smoke" coming out of your mouth that you must be smoking. It's why those same people will insist that even though you're using a PV, you haven't quit smoking. I don't think using the term e-cigarette is very helpful in that situation, either. People fear and even hate what they don't understand. Unless you can convince them otherwise, most people can't be bothered with the facts because their minds are already made up.
