Back in the days when my fiend was really bad with heroin
(using £50+ a day easy for a couple of years) he would inject all sorts of things, one of them was diazepam
tablets and he also injected temazepam
tablets. My fiend is extremely lucky he didn't kill himself doing this stuff cause he used to do it quite often, he was especially lucky when he injected 'Bensidine' (sp) white 10mg diazepam tablets, his whole body literally fizzed, that's the only way he can describe it and i think he was VERY lucky nothing bad happened, in fact maybe something did happen but he just wasn't aware of it.
My fiend had considered that injecting temazepam capsules would be much easier because they are already in a very fine powder form, but he has no idea if the powder would just sink to the bottom like sediment (which is what he thinks might happen) or if it would be suspended in an 'emulsion'. Either way it's a bad idea and could end up causing serious problems like vascular occlusions (blockages in the blood vessals, veins and arteries) and if they happen in the small vessels in the brain it could cause a stroke or if it happened in small arteries in the heart it could cause a heart attack.
Looking back my fiend wonders how he managed to get away with the shit he would inject and if there are such a thing as infinite universes where every possible outcome happens then he is certain that he is dead in at least half of them
In any case, the majority of benzo
's just don't dissolve in water and even with injecting water soluble opiates
and other pills is a very bad idea (unless it's done properly with wheel filters and proper extractions, this can't really be done with benzo's in the same way), so injecting non water soluble pills is crazy. MY fiend won't ever do it again just because it isn't worth it, the oral bioavailablity of benzo's is very high and oral absorption is rapid especially with a hot drink (and crush em with your front
teeth). My fiend does say that he used to love injecting 7 x 10mg diazepam tablets in a 2ml barrerl with 2 bags of heroin, what a fucking buzz. Even although he liked it a lot, he can still get almost identical effects by eating the valium
and waiting for them to start taking effect then use the heroin in his preferred methods of administration.
Don't risk injecting pills, epically benzo's it just isn't worth it, and my fiend is just extremely lucky he didn't do himself some serious harm, well it did cause an abcess in one occasion that led to quite a nasty cellulitis that required hospital IV anti biotic for 5 days.
