I've gave my two pence in one of your previous threads. IV heroin doesn't just kill you. It takes your friends, your family, your treasured belongings, your home - you know the kind of things you always hear people saying "these things we take for granted". Then - it takes your mind, your esteem, your whole perspective of your own self worth. Then, only then - will it kill you, that is of course, if you haven't already killed yourself through an accidental OD or suicide. Anything or anyone you ever held dear to your heart - you had better be prepared to kiss goodbye to FOREVER. Because once its gone man - that's generally how it stays.
Second chances are far and few between when it comes to opiates - never mind when you've got the point of injecting the devil's brown snow.
I'm physically dependent on opiates. And I have perfect veins. Hell the homeboys use to joke around that I could rent them out to other junkie

... if only, getting paid for the use of my veins - does that count towards use of my mu-receptors too?
All joking aside. Everything I've just said there, about losing friends, family, your self worth etc.. I've lost it all. Through the oral use of pharmaceutical grade opiates. The only time I've tried to inject was when I was drunk as shit once and a home boy dared me to shoot some water (It was a double dutch darwin dare..... you know how those go). I got the needle under my skin - I think I popped into the vein - then I shite out. Pulled it out, and gave myself a good slapping.
Now if I havent managed to talk you out of this - bin those lemons. Get some citric acid sachetes. Get some alcohol swaps too. And for the love of Charles Darwin himself.... TREAD CAREFULLY WITH YOUR DOSAGE. Your you might just be the winner of Charles Darwin's infamous award.
But please... don't do this. You'll have hell of a fine time snorting or smoking horse.
