I just spent 2 days smoking (mostly, tried oral and snorting too) 4 - 5 grams of etaqualone, despite the fact that it only gave me a physical drunken effect the first day, then a slight weird sedated feeling the second day (something comparable to a low dose of baclofen or gabapentin). I have absolutely no idea why I kept going, and by the time I was down to the last gram or two I could barely feel it except for a bit of sedated tiredness, but I just kept going and going. Not only that, but the smoke was foul and burned my throat.
Left a filthy residue in my pipe too, and in hindsight I'm starting to wonder if it couldn't have done some actual damage to my throat or lungs, given that I was inhaling the hot vapor of a non-water soluble substance. Ugh, the stupid things we do chasing a feeling.
