But neither ever got anywhere with it. Of course neither Democratic president had an Imperial Presidency and a "Justice Department" who took direct orders from them, either.

This doesn't alter state taxes. There is a federal tax on schedule 1 & 2 drugs that is the IRS rule 280e, cooked up during the 1980s drug hysteria. It has created barriers to legal businesses as the rules were created for "crack houses". Weird particulars where the drug's purchase is a deductable expense, but rent on the facility isn't. Also blocked credit cards. This still leaves cannabis on schedule 1 for all but state licenced businesses.

How is that gonna work? Will we need to keep pedigree papers with our stash to prove its status?

Eventually once the racism is the norm then extra class based rules like needing a Federal Card will come in.

With Trump's likeness on it, no doubt.

in Baggies. Factory sealed in a sealed bag in the trunk isn't getting questioned.
The open bag on the back seat?

will cannabis businesses be allowed access to the banking/lending sphere now?

I don't believe this applies to any state legalized Recreational Businesses.

you never know. They have already begun threatening and encroaching on state laws for other things like AI and age-verification stuff.

So they can do something like, say, prohibiting them from voting… or punish them in some other way (such as, ineligible for any government benefits?).

Both methamphetamine and cocaine are in Schedule II.

I must bring this up again: Drugs aren't scheduled based on how bad they are for you. They are scheduled on two bases: potential for abuse (the government considers any use of drugs for recreational purposes to be abuse) and accepted medical uses.

Schedule I: high potential for abuse, no currently accepted medical use
Schedule II: high potential for abuse, accepted medical uses (everything below this schedule has medical uses so I won't type it four times)
Schedule III: moderate potential for abuse
Schedule IV: low potential for abuse
Schedule V, which I think of as the "cough syrup schedule": almost no potential for abuse

Since a huge number of people use cannabis specifically to get high on it, it has a high potential for abuse; therefore, it should be Schedule II.

But here's the thing: the cops throw people getting high on Schedule III drugs in jail with the greatest of pleasure. Trump definitely has not ended the drug war with this decision.

As an aside, does anyone remember an article National Lampoon Magazine published in the 1980s to roast the drug war, entitled "The War on Lomotil"? The article claimed thousands of teens were dropping Lomotil - a drug the DEA lists as an example of a Schedule V drug - so they wouldn't have to go to the bathroom so often.
