Many years ago I was told that the word “roach”, as in the smoked-down end of a marijuana cigarette, came from the fact that it looked like a cockroach. I found that explanation reasonably convincing, as the butt does indeed look like the flat body of a 'roach. Not the most appealing thing to put in your mouth, either.
yes, that’s the column I was referring to . . . it’s an old one and I’m a Straight Dope ingenue, so I don’t think I posted my comment correctly, with rererence to the original column. Sorry, old timers.
Back in the old days, (when marijuana smoking was not only illegal, but, if you can believe it, frowned upon) it was probably necessary to hide the remnants of one’s partaking – perhaps in the back of a drawer, or cabinet; where incidentally, the creepy, crawly original name bearers are often found? (It seems only logical)
In the early sixties we used to say " get your head tight" the pot back then gave you a feeling of a band being wrapped around your head. Doesn’t do that anymore.
Is there a possibility that the “roach” term may have come from or been influenced by the Mexican song “La Cucaracha”? A verse referencing marijuana dates to the Mexican Revolution of 1910-1920.
