Meth was first synthesized prior to 1920. It wasn't illegal in this country for decades after that to my knowledge.

Of more relevance is the date when the household-ingredient method of preparation was devised; I'm sure that was considerably later than the 1920s.

No, you were making the argument that meth is a product of the drug war, which it is clearly not. You said, "[T]hanks to decades of drug criminalization drugmakers have finally come up with that drug in meth." Meth was created before the drug war ever started. It is true that few people would be making it in their kitchens from household ingredients if it were legal and available for purchase ready-made from the store, but that really isn't relevant to the question of whether meth is a product of the drug war or not.
