No they can't. users have to figure out using the instructions with the product how to work it.
Why can they do this? When I buy a multi-band radio there is no law saying the vendor that
sold it to me is required to walk me through. There is no law saying he can't. However there is now a law
saying that when it concerns our product they can not do this anymore concerning our product.
Why? For the chillin'. End of story.courts will agree. It's over.
Safety isn't the issue. If it was we wouldn't be here.It would be Nice to Challenge the FDA in Court if the FDA wanted to Fine Me for showing someone How to Safely Use a Product that I sell.
This would be ok if this is where it ended. Every step of the way requires a response that documentsThey're not going to shut anybody down or seize inventory just because a store fills a tank or something equally trivial. Worse case scenario would be an initial warning letter and then you could decide whether to fight or capitulate. If you don't capitulate, then fines would start out small and escalate.
thoroughly in detail what your violation was and how your procedures in detail allowed this. How in detail you have changed your procedures to stop this backed up with research proving this. You may
be required to submit studies proving that this behavior did or did not change the vapor producing
quality of the device or affect the user,or nonuser of the device depending on age,likelihood of them being dual users,underage,etc... etc..etc..
