That’s not part of a trade summit. And why doesn’t the Dept. of Commerce have control over regulation and enforcement of this “prohibited illicit” (redundancy yours) commerce in drugs? Very strange.

That’s not part of a trade summit.

“The United States is a party to the Single Convention on Narcotic Drugs, 1961, and other international conventions designed to establish effective control over international and domestic traffic in controlled substances.” —21 USC Sec. 801 (7)

It's an international trade agreement, that the United States is a party to, that places restrictions the trade in illicit drugs. Among other things it provides that:

"Manufacture" means all processes, other than production, by which drugs may be obtained and includes refining as well as the transformation of drugs into other drugs.

There is a massive trade in prohibited drugs both domestically and across national borders.

Pesky old reality.

On the intent of the commerce clause with regard to manufacture, by one of the men who wrote it.

James Madison to Professor Davis

1832
Letters 4:247, 251--54

Attempts have been made to show, from the journal of the Convention of 1787, that it was intended to withhold from Congress a power to protect manufactures by commercial regulations. The intention is inferred from the rejection or not adopting of particular propositions which embraced a power to encourage them. But, without knowing the reasons for the votes in those cases, no such inference can be sustained.
