by Steve DeAngelo

Ed Rosenthal and I emerged from the same underground cauldron of culture and politics known as the Youth International Party, more commonly referred to as the Yippies or sometimes even just Yippie! (The exclamation point was very important to us.) Although the Yippies were often written off as the court jesters of the New Left movement of the 60s and 70s, the Yippie! movement gave birth (or at least shelter) to a cadre of remarkably effective and absolutely determined cannabis activists who would go on to play crucial roles in the formation of the modern cannabis movement and industry.

Like old CIA officers, old Yippies never really retire. Ed and I are both fortunate to have now reached elder status, but in the early 1970s I was just about the youngest Yippie and Ed had been around the scene a lot longer; he was this impressive, distant figure I heard about long before we met. I think I first met him at the 1975 White House Smoke-In, though it could have been the 1977 White House Smoke-In, or possibly while smoking or even selling weed in a smoky commune somewhere.

Marijuana Growers Guide , the original edition of this book, seems to have always been present in my life, and I recall my reaction upon first seeing it; it was one of the most powerfully subversive books ever written. Here was an extremely specific, detailed, impeccably researched and written guide to producing the best cannabis in the world. The only other instructions for growing cannabis that I had seen had been mimeographed handouts passed from hippie to hippie, or the rudimentary drawings sometimes published in underground newspapers. I could tell right away that this book was going to change our world.
