Injecting the pills,even assuming you found a way to make the Ativan dissolve(which would require certain chemicals and the knowledge of how to do the process,proportions of solvent to solute etc....which it doesn't sound like you have),you wouldn't really get any higher,just a faster onset.I've been taking benzos for decades and the only times I've ever done them intraveinously has been with liquid preperations made for injection.Even injecting pills like hydromorphone that break right down in water carries a lot of risks,especially of abscess.It can cost you an arm and if the infection hits your bloodstream and goes septic it's probable that you will die.I know many will disagree with me but the best way to get more out of Ativan(a pretty weak benzo IMO)is to crush them up between two spoons into a fine powder and sniff them.It hits within a couple of minutes and comes on way stronger.I regularly do this with my Xanax and feel them a lot better that way,it just doesn't last quite as long.Blow your nose really good first and cut the powder into a bunch of thin lines,doing a line or 2 up each nosrtil and wait a few seconds before repeating unitil all powder is sniffed.The idea of small,thin lines is that you don't want the mucosa to become caked up with binders and fillers.Doing it this way ensures that what you sniff will have maximum contact with the membranes and have a chance to absorb better.You don't want to sniff as hard as you can either since you want the least amount possible to go down your throat.After every line is consumed,wait 4 or 5 minutes and dip 2 fingers in water and sniff a bit up your nose.to clear your nostrils.Only then do want to catch a drain.Just because most benzos are not water soluble doesn't mean they aren't absorbed intranasally.Other factors come into play with this.I've read studies supporting this although I couldn't begin to tell you where to find them.I'm not really tech savvy,computers are relatively new to me.A lot of stuff I find on the internet is by accident (like Blue Light) and a lot of times I find something,read or watch it,then can't remember how to find it again.But I discovered sniffing benzos a few years ago.I'd heard of people doing it but thought it was just stupid until I finally tried it and to my surprise it worked a lot better than just eating them.But for heaven's sake,don't attempt to iv benzo pills,you're just asking for a trip to the emergency room to have an abscess surgically removed or worse.I've got a needle fixation and if shooting benzo pills were possible I would have been doing it long ago.It's ultimately your decision but it won't work and I'm trying to save you a shit ton of unpleasantness.There are 1 or 2 that break down and are shootable (can't remember which ones,I think midazolam is 1 but am not sure) but good luck finding them.Sniffing them and, to a lesser degree, taking them sublingually are the best ways to get the most bang for your buck with benzos like Xanax and Ativan.For some reason I couldn't get it to work with Valium and Klonopin's mintyness just causes me to sneeze them right out,wasting them.But whtever you do,I highly advise against shooting pill form benzos.
