I do agree it is a very careless statement designed with only sales in mind. It is no doubt slick, but calling it a lie (not saying you did) is up for interpretation as well. I am not in law so I do not know if a savvy lawyer could make it seem as though there was an actual guarantee there. The beginning word "No" could be seen is saying that they are in fact saying there is none of the asked chemicals present in their juice. The fact that they ended by saying "when inhaled" could be a sticky point as well since the approved ingredients are not approved for inhalation, but I still saw this as puffing and would not have taken it as an actual assurance. I should have used the word "probably" not actionable. For the record I would have steered clear of any vender with this response, but I would not have felt the need to call them out publicly.
You do not need to apologize. I understand what you meant. I must be confused as to the point of a forum. I thought it was to post views and experiences so that people could see there was a myriad of opinions and ways to skin a cat, take it all in, then make your own assessment based on what works for them. I usually try to be very careful of the words I choose so as not to offend, force or attack. I didn't know that by stating an opinion or relating an experience was using fear mongering to influence another. I will be more careful and watchful for those trying to influence me in the future. Thanks for the heads up.
