Hi Joe F,

tho they do indeed praise dope, are mainly propaganda against its illegality, and only secondarily celebrations of its effect on those who smoke it.

I apologize if it was unclear: I was noting those song precisely because of their other dimension *besides* "We love to smoke cannabis." The latter are indeed common in the reggae oeuvre, however, since they don't interest me much personally, I don't have many at the tip of my tongue (I prefer love songs and such!).

But an example I can offer that may be more on your target is the well known "Pass the Kutchie":

Pass the Kutchie

It's doggerel verse, but it's more about the "vibe" of just sitting around in a circle and passing the pipe around.

Pass the kutchie pon the lef' hand side
Pass the kutchie pon the lef' hand side
It a go bun, it a go dung, Jah know

It was a cool and lovely breezy afternoon
(How do feel when you got no herb?)
You could feel it 'cause it was the month of June
(If you got no herb you will walk an' talk)
So I lef' my gate and went out for a walk
As I pass the dreadlocks' camp I hear them say
(How do dey sing when you heard dem sing?)

Pass the kutchie pon the lef' hand side
Pass the kutchie pon the lef' hand side
It a go bun, it a go dung, Jah know

So I stopped to find out what was going on.
(How do you find when you make your stuff?)
For the spirit of Jah, you know he leads me on
(Them all have a leaf at the dreadlocks' camp)
There was a ring of dreads and a session was there in swing
I could feel the chill as I see and heard them say
(How do dey sing when you heard dem sing?)

Pass the kutchie pon the lef' hand side
Pass the kutchie pon the lef' hand side
It a go bun, it a go dung, Jah know

As far as your imagined scenario about (19th century?) songs praising cannabis to get through labour goes, I am not an expert on pre-recording industry Jamaican songs, but FWIW so far as I have heard a number of them, sorry I can't remember hearing any such thing.

Is the birth-control pill a drug you'd consider under this topic? :-) I do know of a few Jamaican songs about that!
