However, Daniel House, who owned C/Z Records, disputed these perceptions in 1994. House stated that there was "... no more (heroin) here Seattle than anyplace else"; he stated that the "heroin is not a big part of the music culture", and that "marijuana and alcohol ... are far more prevalent". Jeff Gilbert, one of the editors of "Guitar World" magazine, stated in 1994 that the media association of the Seattle grunge scene with heroin was "really overblown"; instead, he says that Seattle musicians were "... all a bunch of potheads." Gil Troy's history of America in the 1990s states that in the Seattle grunge scene, the "... drug of choice switched from upscale cocaine the 1980s to blue-collar marijuana." "Rolling Stone" magazine reported that members of Seattle's grunge scene were "coffee-crazed" by day on espresso and "... by night, they quaffoceans of beer – jolted by Java and looped with liquor, no wonder the [grunge music sounds like it does." "Some scene veterans maintain that MDA", a drug related to Ecstasy, "was a vital contributor to grunge", because it gave users a "body high" (in contrast to marijuana's "head high") that made them appreciate "bass-heavy grooves". Pat Long's " History of the NME" states that scene members involved with the Sub Pop label would have multi-day MDMA parties in the woods, which shows that what Long calls Ecstasy's "warm glow" had an impact even in the wet, grey and isolated Pacific Northwest region.
