Also Hooker by Paxton
Well, I rise at 4 in the afternoon.
I take a match and a kitchen spoon.
I wrap my arm in an old necktie
And I find religion on the very first try.
Bitches’ Brew by Miles Davis. Instrumental, but the intent is unmistakable.
Two by The Moody Blues…
Legend of a Mind (Timothy Leary’s Dead)
Nights in White Satin
Motorhead, by Motorhead:
Sunrise, wrong side of another day,
Sky high and six thousand miles away,
Don’t know how long I’ve been awake,
Wound up in an amazing state,
Can’t get enough,
And you know it’s righteous stuff,
Goes up like prices at Christmas,
Motorhead, you can call me Motorhead, alright
Junkhead, by Alice in Chains:
Hey, what’s my drug of choice?
Well, what have you got?
I don’t go broke
And I do it a lot
Waiting for the Man, The Velvet Underground:
He’s never early, he’s always late
First thing you learn is that you always gotta wait
And I love love love, The Pusher, by Steppenwolf:
You know I’ve smoked a lot of grass
O’ Lord, I’ve popped a lot of pills
But I never touched nothin’
That my spirit could kill
You know, I’ve seen a lot of people walkin’ 'round
With tombstones in their eyes
But the pusher don’t care
Ah, if you live or if you die
Snips from Truckin’
What in the world ever became of sweet jane?
She lost her sparkle, you know she isn’t the same
Livin’ on reds, vitamin c, and cocaine,
All a friend can say is ain’t it a shame? …
also -
Sittin’ and starin’ out of the hotel window.
Got a tip they’re gonna kick the door in again
I’d like to get some sleep before I travel,
But if you got a warrant, I guess you’re gonna come in…
Busted, down on bourbon street, set up, like a bowlin’ pin.
Knocked down, it get’s to wearin’ thin. they just won’t let you be, oh no.
True; not a song about drugs *per se*, but with enough drug content to qualify, no?
And - maybe the ultimate drug song....
"Plop, plop, fizz, fizz, oh what a relief it is."I’m rather partial to “Waiting around to die” by Townes Van Zandt.
I assume you mean Rainy Day Women #12 & 35?
Yeah - That’s it. Thanks.
I second White Rabbit, and coming in second is pretty much any song by Steely Dan, if you include alcohol as a drug.
How about every song by the Grateful Dead?
Might as well include every song by Phish, too!! 
This comment pisses me off a little bit. I tried to think of a snarky reply but couldn’t come up with enough vitriol. I’ll just leave it at this: Your comment showed a great deal of ignorance about the music of both of these bands.
So many good ones have already been mentioned, but I’ll add a few that have yet to be mentioned…
L.S.D. - The Pretty Things
Get Higher - Black Grape
Junker’s Blues - Champion Jack Dupree
Little White Pills - The Meat Purveyors
Now I Wanna Sniff Some Glue - The Ramones
There Goes the Neighborhood - Sheryl Crow
Take Ecstacy with Me - Magnetic Fields
Scooby Snacks - Fun Lovin’ Criminals
How come nobody has mentioned Huey Lewis’ I want a New Drug? 
Oh yeah, forgot Smack Jack by Nina Hagen.
“It’s a shorrrrrrrrrrrrrt term solution…”
The President’s Council on Psychedelic Fitness off of Basic Blues Magoos always makes me want to drop acid with the ghost of LBJ.
Steppenwolf’s “The Pusher” has gotten a couple mentions (the long version on Early Steppenwolf’s best), but no one’s yet mentioned “Don’t Step on the Grass Sam.” And what about In-A-Gadda-Da-Vida and Incense and Peppermints? Great drug songs all!
*drops in for another hit off this thread
Smuggler’s Bules by Glen Frey
Treetop Flyer by Stephen Stills
Candyman by Bruce Cockburn
Kid Charlemagne by Steely Dan
Anyone got some brownies or something?
A lot of David Peel’s stuff:

New Riders of the Purple Sage - Panama Red (Album)
http://www.nrps.net/music/#panamared
Merle Haggard - Okie from Muskogee, White Line Fever, etc.
Sly and the Family Stone - Want to Take You Higher, (many others)
Same band, but I’d nominate “Junkhead” rather than “God Smack”.
Buckcherry - “Lit up”
Afroman - “Colt 45”
“Brain Stew” by Green Day
And if Velvet Underground’s “Waiting for the Man” has been mentioned, then why not Dylan’s “Mr. Tambourine Man”…
