I know most are not water soluble except midazolam, but i have found that crushing xanax bars to a fine powder (pill is very hard) and snorting is quite effective and gets you barred out quick. I just snorted 60mg temazepam and feeling quite good bout to do 30 more. I don't know how but it definitely works to snort them, water soluble or not. Now I would love to get my hands on some versed, or dormicum pills...the person that helps me out on that can expect something good from me.
Some benzos seem to have higher bioavailability when insufflated than others, but in general it's a waste. It still works to an extent, but if having it kick in quicker at the expense of losing a good chunk of it is worth it to you then knock yourself out. Besides, there are certain drugs where having it kick in abruptly are very conducive to the euphoric profile, such as opiates or stims. But downers (and don't me wrong, I love downers) don't really have a "rush" to speak of.
ya idt i have ever snorted any benzo and do not plan on it. a friend has recently being telling me about a process involving some kind of alcohol extraction where you can IV benzos, but I have no interest in that. If i have 5 bars sitting in front of me, im not going through a 45 minute process to get them in my body, they are getting chewed up and washed down with a beverage asap!
I've snorted benzodiazepine pills before, but then I realized that it was a pill and could be placed into my mouth and swallowed for relatively same effects, effects last much longer. Makes you feel like less of a weirdo also. Pills are meant for your mouth; powders for your nose. Turning the pill into a powder [a complicated, messy, possibly unclean, possible loss of material] seems like a great idea at first but once you do it, it's never as good as you pictured it due to the reasons above. It is much more discreet, clean, and simple to place the pill in your mouth and swallow it.
While there is the chance of a loss of valuable drugs when you crush a pill, if you do it carefully any specks of powder that fall by the wayside should only be a negligible amount that you wouldn't miss anyway. And I don't see how snorting pills makes someone a "weirdo", and even if it does what's wrong with that? Some pills are better for snorting than others. The old crushable oxycontins or roxis are fine for snorting, since they only contain oxycodone and aren't that big, therefore not too much powder. Whereas percs are not, due to their low oxy content and bulkiness, not to mention all that apap. You get a faster onset and better rush by insufflating certain compounds, which most people (at least people using them with the intent of getting high) would prefer over a somewhat longer duration.
