The "46 reasons" were actually one reason based on flawed science.
A 1967 study had shown that LSD could cause a two-fold increase in chromosomal breaks in cell cultures. But subsequent studies showed that the breaks were a result of the concentrations of the drug being used — and that pretty much ANY substance, in similar concentrations, would cause chromosomal breaks. In fact, there was no evidence that LSD caused significant chromosomal breaks or was a carcinogen.

This curious device was featured in
Mechanix Illustrated (July 1938), but no info was given about the inventor.
So I searched the patent archive. This patent
granted to Justin Sholes in 1939 seems to be it:
Peter Hlookoff had an unusual strategy to avoid being convicted for possession of marijuana — he always carried a container of alfalfa with him.
His reasoning was that alfalfa and marijuana smell similar (so he claimed). So if the police ever arrested him for possession of marijuana he could claim that it was actually alfalfa they had smelled (or seen him smoking).
This strategy was put to the test in Dec 1967 when the police raided his apartment and arrested him for smoking pot. During the subsequent court case his defense led to the magistrate arranging for a court employee to smoke marijuana so that its smell could be compared to alfalfa.

Unfortunately the courtroom experiment was cancelled before it took place, and the magistrate ended up finding Hlookoff guilty. He didn't buy Hlookoff's follow-up argument that if, perhaps, it had been marijuana he was smoking then someone must have (without his knowledge) put marijuana in his alfalfa container.

Hlookoff's roommate, Marcel Horne (a professional firebreather whose stage name was 'El Diablo'), later
wrote an autobiography in which he revealed that, yeah, they were absolutely smoking pot when the police raided their apartment:
It was now December 12, 1967, Peter Hlookoff, who was now co-editor of the Georgia Straight, and I were up in my room around one o'clock in the morning. I was lying under a sun lamp to get a tan and was high on grass. Peter sat in the middle of the floor with a roach in one hand and enough dope for three cigarettes in a plastic tube on the floor beside him.
We were rapping away very stoned, when we heard someone coming up the stairs. The next thing we knew two cops in uniform walked into the room. Peter tried to drop the roach but the cop saw him. I was too stoned to think properly so I just lay there watching the nightmare. The cops put us up against the wall and frisked us. "Who does the marijuana belong to?" We both answered, "What marijuana?"

Nov 1976: Roxbury District Court Judge Elwood McKenney, presiding over a cocaine possession case, announced that he would need to try cocaine himself before he made his ruling... in order to be able to make an informed decision. He recessed the trial until he had done so.
Palo Alto Times - Nov 2, 1976
Judge Elwood McKenney
About a month later, McKenney abandoned his decision to try cocaine, saying that all the publicity about it had distorted his intent.
But he then proceeded to rule that the Massachusetts statutes forbidding the possession of cocaine were unconstitutional.
Obviously his ruling must have been dismissed or overturned at some point, otherwise cocaine would now be legal in Massachusetts. But I haven't been able to figure out when that happened.

I'm sure cocaine would soothe an irritated scalp, but I can't imagine why it would cure dandruff.
