I know this is an old forum, but I have to put my 2 cents in.
First off, in no way whatsoever did the poster above me imply that snorting
heroin is safe. He/she did not say," yea snorting will keep ypu from overdosing, so go ahead and do it. The 1 red star should be removed. An inaccurate critique will not help anyone. Afterall, that seems to be the purpose of this great website, which has helps many people that I know stay safe. He/she even said to use safety techniques that someone they know has obviously used before.
To the OP... the poster above me made a very good point. You can always redose, but you cannot undose. So their advise to use small amounts until you reach your happy place is the safest way, next to abstaining of course, of preventing an overdose if you insist on snorting. And they are indeed correct about the fact that it is "harder" to od snorting. There are far more deaths and non fatal overdoses from injecting than snorting or smoking. You could pin that on the assumption that most heroin
users prefer to IV their product. That particular statistic I could not find, although I did try for future people in need of the information.
One more thing, just to be as safe as possible, I would start with a minuscule dose. And by that I mean as small as humanly possible, but just enough to taste that it is indeed what you payed for. The reason I say this is because I know many, many people who has recieve something other than what they payed for. These people I know buy their product in sketchy neighborhoods, and so the people are willing to beat you woth just about whatever they can find. Whether that be rat poison or lactose powder. Always be sure that you are not ingesting something even more harmful than heroin. Word of advise, if it smells like bleach, throw it away. If it burns, really really bad, you should probably get rid of it. If that burn last more than a minute... cut your losses and thrpw it out. Trust me, I know people who have been put in bad situations because of fake or tainted heroin.
Be as careful as humanly possible people. Your life may depend on it. Good luck.
