sees that swiy's in the UK, in which case, swiy is getting heavily cut heroin
. If 60% of your 'heroin' is cut, then you've actually got alright gear........it's a sorry state of affairs.
Basically, the vast numbers of impurities and possible bacteria in street heroin make subcutaneous and intra muscular injection very bad ideas.
When you inject into a vein, all the impurities, along with the heroin itself, are immediately moved around the body, where the impurities can be filtered out in the liver/kidneys, which is what they're designed to do.
However, when you SC or IM, the highly unsterile solution just sits there, for hours and hours, only being absorbed into the body very slowly.
While this does mean that it may keep you well for longer, (although without any real high), it also means that the risk of abcesses and infection is really pretty high.
Think about when you miss, it hurts, and leaves a lump which can last days to go down. Sometimes this area becomes very sore, and hot and red. And sometimes it turns into an abcess. Which is horrible.
However, when you miss, generally only a small amount of the unsterile solution is left outside the vein, because when you feel the pain of a miss, you stop injecting.
On the other hand, if your actually using a miss as a route of administration, i.e. SC/IM, then your purposefully injecting a full dose out of the vein. As this is a much greater amount of unsterile solution sitting around agitating and possibly infecting the surrounding tissue, the likeliness of an abcess is greatly increased.
Both IM and SC are intended for completely sterile solutions. Obviously IV is originally intended for this too, however, as explained, injecting an unsterile solution IV, generally causes considerably less damage, as it is considerably easier for the body to filter and break it down immediately.
It's not unheard of for people to use this route, particularly if they're using purer H4, which is water soluble, and generally of greater purity. But likewise, and especially with H3 and tar heroin, it's definetly not unheard of for these people to suffer nasty infections and abcesses.
So in conclusion, swim would advise you to stay away from these routes of admin, as the solution is just too dirty.
Swim would advise swiy to try and buy some methadone
, as it's the cheapest way to keep you well. It's certainly what swim would do, it's saved his bacon many times.
