Inspired by the Beach Boys' live jam session recording of Barbara Ann while allegedly on acid, Dopesmokers of the World Unite and Take Over sounds like a bunch of stoners 
having one hell of a good time. Even better, it's a sing along, and even better than that, it's clearly meant to be sung along to while stoned. Not that you have to be baked to enjoy it. As one reviewer put it, it sure does 'make you want to clap and sing along'. And I'm pretty sure she was sober :)
Dopesmokers is also one of the songs that got Blind Uncle Harry banned by the Indiana University Union Board at a Live from Bloomington performance. That, and suggesting the audience could substitute singing 'Burn down the Kelley School of Business' instead of singing 'Burn Down the High School'.
Dopesmokers is a stoner's anthem, but with a message- if everyone smoked weed there would be no more wars, there would be no more Wall Street, and life would be one big giggle fest. Well, maybe, but singing along and bopping your head to it will definitely brighten whatever kind of shitty day you happen to be having. 
"Cuz everything/ That's destroying the world
Is impossible to do/ When you're stoned
You can't operate/ Heavy machinery
When you're stoned"
DOPESMOKERS OF THE WORLD UNITE AND TAKE OVER
by Blind Uncle Harry
Dopesmokers of the world unite and take over
If we were in charge, there would be no more wars (x2)
Dopesmokers of the world unite and take over
Well the stock market, it would crash
Hallelujah, hallelujah, hallelujah
Cuz everything that's destroying the world
You look like you could use a giggle too
So hey Barack, Barack Obama
Life won’t seem so complex
You’ll forget all about who to put
Cuz when you’re stoned
So everybody, won’t you sing along
La la la, la la la, la de da
La la la, la la la/ la la la/ la la la
So dope smokers of the world unite & take over (x4)
