Yeah.. It could make its way to UK, the fent dope, which it seems to be 80-95% fent and then a little 5-20% H, then whatever else its cut with... It is fucked. I stopped doing H, and all full agonist opioids, luckily, right around the time this shit started really showing up.. Now its a fucking epidemic where I live, in the US! its some scary shit! and yeah, if you haven't smoked the H off of foil, you haven't had the true H smoking high! I am assuming you have base heroin where you live? As you said you have to use citric to break it down, and that your in the UK.. I know there is a lot of base(freebase) heroin there, basically made to be smoked.. Though you can shoot it, as you said with some sort of citric acid, like you would use to break down crack to shoot.. I have never seen/tried base heroin before, its not very common in the US.. In my are, we have anything from black tar, to tan-beige-off white powder.. I would usually slam it.. but if I was in a jam, and didn't have time, I would either sniff the powder(not sure if this can be done easily with base dope, I wouldn't think so though, it would be like trying to sniff crack..)dope, which still got me rocked! I mean, I liked all 3 ROAs a lot, smoking tar was straight too! If I didn't have any rigs, I would sometimes smoke the tar, off a piece of foil, running it up and down the foil, leaving behind a thick black trail which could also be smoked.. did this with OCs a lot too, and oxy IR 30s.. All of them, are fun to smoke, and give an awesome high, if done right!! if you cant hold it in well, though.. its a waste, and nothing will happen really, you have to hold in huge hits, and try not to lose any smoke/vapor chasing with a lighter under the dope on foil, and a tube to inhale the smoke/vapor.. it is tricky for some people, and they just assume it sucks done that way, even when they did it totally wrong, and hit it like you would a cigarette, lightly inhaling and exhaling almost immediate.. its like when smoking crack, you have to hold that shit in!
I used to be fucking terrified of needles as a child! then I was basically told one night by my friend who was an IV addict of all opiates, if I slammed it he would give me some oxy for free! It was pretty fucked up thinking back, that someone bribed me, with my DOC at the time, to give me 3 30mg oxy IRs if I shot them! So I did.. and I liked it, a lot! It was the only time, doing oxy, that when I slammed oxy I actually got super faded! it nowadays, doesn't do a whole lot IV, but give me a fast onset, not much of a real rush, like it did that first 90mg oxy shot I did.. So, after that, I lost my fear of needles.. and still continued to sniff and smoke my oxy and dope... Then about 5 months after that first shot, I came up on some free dilaudid, which I had never done at that point.. so I heard it had to be shot, to really be worth doing, and I got a new rig, and shot an 8mg dilaudid... WOW! That's when shit hit the fan with my IV addiction!!! After that, I never really looked back, and just gradually began shooting everything... stuff I had always sniffed, taken oral, plugged, or smoked... IF it was an opiate/opioid, and able to be shot easily.. I would bang it.. and when I ran out of rigs every so often, and they were to foul to be re-used again, since I had a hard time getting them back then, I would sniff/smoke my shit.. depending on what it was.. opana and dillys, I would sniff as its the next best thing, to injecting, and the ER opanas, cannot be easily prepped to shoot, which I normally only found, not to often did opana IRs show up.. mostly the ERs which, are useless for anything but sniffing.. The IRs get you sooo nice... better than any dope I have ever done, opana(oxymorphone IRs) are the best opiate ever to me.. when ived.
Just be careful man, and try smoking the H off of foil! You may be pleasantly surprised at how good it feels.. hold it in in huge hits, as big as you can take, hold the foil tilted diagonal and let it slide down the foil, with low heat of a lighter underneath the dope, and inhale through a pen tube or straw of some sort, without missing any smoke!!! I cant see smoking it out of a crack pipe, working well at all, as it needs to be smoked, or vaped without seeing direct heat from a flame!!! it will ruin it if not vaporized correctly.. And thanks, btw... it was hard to get myself to stop doing dope/pharm opioids, and go to subs, and now I am hooked on subutex, slamming it! cant stop, it too feels pretty great, subtle, yet nice and opiate like feeling at the same time, just lacking in the rush area, and the high isn't as punchy, but I like it nonetheless.. Stay safe!
