I don't even necessarily hate weed puns/references*, it just seems like that's only been a Sleep post reformation thing if you exclude Dopesmoker. Which, regardless of intent, was never even the public name of the album until a solid decade after I first heard it.
*Ok, I actually DO hate weed puns/references in music...but I mostly overlook it for bands that I really like the music and it's inseparable (Weedeater, Bongzilla, etc.). However, I just don't want a giant pot leaf on a shirt or a sticker, so I've never bought any Sleep merch, even though I've liked the band a long time and they were semi-local to the area I grew up.
