I don't know about what shady dealings the FDA was involved in with this case, but governments generally tax all economic activity within their jurisdiction. There are even guidelines for reporting income on stolen goods on the IRS website. Lying to people about addictive potential, causing many of them to die, for a profit is far and away from a government collecting collecting taxes on economic activity.
