This is possibly intentionally referring to a singular group supply. Likewise, in a household or workplace, you could say that you had some of "the coffee", if you were partaking in the household or workplace group supply.

It was from a comedy podcast where Conan is always using intentionally silly terms for that. I think they were just riffing on that, intentionally making it sound stupid.

Pedantry: the theory th' interwebs give me is that the evil weed has also been known as "pot" since the 1920s, and its use, without determiner, is attested in print as far back as 1938, so I doubt that extraneous determiner would be anything but intentional.

Seems ironic to me but I’m not going to listen to the podcast to confirm.

Yeah I'd say it's almost certainly veiled in irony given the context. Something derived from reefer madness stylization. I do it as well, quite literally using that phrase. Tinges of unguided parentalism and the vogue surrounding it - otherwise ignorance.

Very Beastie of them - like in Johnny Ryall where they rap on how the titular character is "better off drinkin’ than smokin’ the rocks".

it's also a believable affectation.

try saying "smoking pot". then say "smoking the pot". Listen to the rhythm. Which one sounds like a flow that a rapper would choose?

Rapper's are wordsmiths. It's an aesthetic choice.

whimsy is dead

reports of my death are greatly exaggerated

oh thank goodness
