breaking news, most of the proteins are avaiable in plants... then it is just a question of refining it. Okay I may sucks at genetics, but in short dna > proteins > molecules... weed > a plant , hero > a plant, cocaine > a plant... find them, they are as old as the creation :).

Then it ask the question of fetanyl, again this a lie, there isn't one fetanil, because of the natural plants being illegal and for fun some research what is called designer drug, meaning that fetanyl can be 100x time stronger than hero, but still used for medical reason, while slightly moddified fetanyl can get to lethal does to a number so low that it can't be considered a drug when death is the only outcome, as so make it a poison and so making trump right in the sense that it can't be a "dealer" as the product will kill 100% of time with doses so low that skin contact with dust can be enough and as such justify that killing of those trading it and so making trump alleged statement reasonable. no I don't have reliable source, I wasn't there :).
