Hon, please don't misunderstand my post as condescending or implying you or your friends are stupid, just want you to understand the reasoning behind why its a bad idea for certain practices. If it saves one person from harming themselves or dealing with the consequences (and their family) then all is good! It is definitely not myintention to be an ass about it...just worried for you.
Girl...before you even continue to consider IVing a pill for Gods sake, make sure you educate yourself more! Firstly, Mr. S didn't say it would not make you nod but it will not give you a rush like you are expecting. The people you see holding a lighter under it and cooking it are very ignorant of the facts. Just because you see them (or those people you see doing it have seen someone doing it that way on TV doesn't mean it is the correct way. And just because they don't use a proper filter and instead use cotton doesn't mean this is the safer and correct way to do it.
And when you snort oxys you are wasting the mojority of the drug. The bioavailability when snorting is low compared to just taking it by mouth.
Also, someone above mentioned that they are able to do I'M and SQ shots but not IV, please don't misunderstand and think that it is ok to I'M or SQ pill shots...this is just begging for an abcess and/or infection.
You NEVER heat a pill for IV shot. When you do this it "melts" down all the. Non drug particles that are in the pill, the fillers and "powder" and non drug parts that are just put there to hold the drug part together. Sure, when you melt them down, it looks like a cleaner shot and like you have gotten rid of all that crap. When you inject that junk intto your veins and then it resolidifes into what it was before, pieces of it floating in your bloodstream, it has to go somewhere eventually it can deposit into the tiny areas of your lungs, heart and brain. This can eventually cause your death. It might happen after one shot or it might take the 100th shot, but is it worth that risk? This is also why it is an absolute necessity to use a micron filter rather than cotton. Not only is cotton a very crude filter but pieces of the cotton itself can get into your injection. Does it sound healthy to have pieces of cotton floating around inside your blood stream? Some of the places that your blood flows to in your body, especially in your vital organs such as heart, lungs and brain have super tiny blood vessels, some of them only as wide as one or two blood cells. So if a piece of a pill or cotton or other junk lodges there of course it will totally block blood flow to that area causing death of whatever part of your body it is in. Enough brain, heart or lung tissue being blocked can eventually kill you.
You also talked about how expensive oxy is but it is going to raise your tolerance greatly once you IV something. When you need more to feel anything it just gets more expensive. It sucks when you can't take that 30 by mouth anymore and feel a thing. And the hydros? Once I started taking more oxy I know cannot get a buzz off of hydros no matter how much I take! And I miss being able to take cheaper, more easily obtained hydros.
So please, read through the threads about all of this and educate yourself before you go there. Everything that Mr. S or I have said will be backed up and reiterated in tons of places here on BL. He has tons of personal experience and in addition I have been a nurse for 20 years (and also a chronic pain patient and drug user).
