I remember being shot-down as a 'newbie' ass-hole when I first joined BL and mentioned insufflating K-pins. Klowns is right on the lipid-solubility but I don't think any benzo has higher BA IN vs oral. Z-meds and hypnotics (midazolam?) are all meant to be good insufflated (I’ve only tried Zolpidem after washing off the silicone coating)I personally agree with Kinfofmean, sub-lingual. I take subutex so am used to SL, and now take most meds that way (if I can stand the taste that is!!)
Tried insufflating some halcion the other day (I’d read about ‘zombie-dust’ triazolam/coke mix), but didn’t seem to work. As for mg/filler, I do sometimes insufflate an 8mg subutex tablet which is def. IME higher BA than SL.
