In terms of absurd things, I had a friend in college who used to snort packets of sweetener and black pepper. I suppose those will be the next to go…
I never thought of this forum as particularly far left. I’ve been lurking since 2005. In the early days, I’d say that the demographic was reasonably mixed, perhaps with the vocal right being slightly more prolific than the vocal left (if not out-numbering them in users).
In any case, I abhor the nanny state. I heard a serious discussion proposing the shutdown of all pseudoephedrine plants in the world and a complete ban on the substance. I’ve given the PE (Placebo Edition) a try, and I’m fairly sure it doesn’t work as well, at least not for me (haven’t done a blind study yet though).
