In which case you have committed fraud. An actual CRIME. Mislabelling Altoids as vitamins does come under the heading of the very real crime of fraud and misrepresentation. A PRIVATE testing lab, similar to but not unlike Underwriters Labs, could quite easily test and publish the results of any substance meant for ingestion. Your Altoids hoax might last as long as a week but I doubt it.
Haven't been to GNC lately have you. Check it out, the bottom of every single box in that place has a disclaimer saying that none of their claims have been verified by testing and there's no garauntee of results. Most of the pills in there are less useful than Altoids but it's not fraud because they use the disclaimer to cover their butt. Once you've used to disclaimer to undo all your promises nobody can say you promised anything and therefore you can't have broken your promises. Disclaimers are the panacea of the suppliment industry. My Altoids hoax should last at least as long as Metabolife.
