As someone who works in marketing, this is one of the cheapest tricks to sell something: "Our product is so good that it is dangerous and we cannot release it to the world". This translates to "Give us a lot of money for limited, exclusive access, sign this NDA (Non-Disclosure Agreement) so no one finds out it's not that good until we make enough revenue and can claim we made a less dangerous version for all, but the better version with more risks is established as high-price product." ;)
@jwildeboer With one caveat: medication. Don't get me wrong, I'm no fan of the pharmaceutical industry, but s substance that has the potential to be medically advantageous also has the potential to be medically dangerous. Often, the difference between medicine and poison is a matter of dosage. Anyone who tells you a medicine is perfectly safe either don't know what they're talking about or are just flat-out lying.
