On bongs. The only bong I ever used was some shitty acrylic one. I just bought a glass on glass straight tube about a foot tall with a bubbler ashcatcher, diffused downstem, and ice notch. I wanted to have a percolator in my bong but the headshop had none that were for simple glass bongs like this. Anyways, my eyes are getting bloodshot sesh after sesh with only mids! My eyes only get bloodshot if I haven't smoked in like 24 hours or if I'm smoking piff. When my eyes are bloodshot it means I'm just done aha. Is it possible to add a perc to a bong? Or should I just not worry about it, is it that much of a difference?
