    Anywhere from 5-10mg to 5-10g, its impossible for anyone to say. Purity of heroin probably varies more than any other drug, not to mention the tolerance of the user. Gotta explain whoever's situation a little better.

    Is this a first time heroin user of first time IV user? If he's already using, try about 1/4 of what you may snort or smoke. This is just a rough estimate, but that seems halfway reasonable. If he is trying heroin for the first time period, then don't IV at all. Seen dudes OD off of a bread crumbs worth when they had no tolerance to opioids, its just too risky.

    nobody can really answer this at all.People all have different metabolisms and what gets one person a bit high might be fatal to another.When I first started on heroin it only took a tiny amount to get me wasted and other people I know could take more than me on their first go even though I had been using regularly.Its also a lot to do with the purity of the gear.Itsd not possible for anyone here to tell you anything.If it is your first time you dont need to inject it.Put a bit on the foil and smoke it you will get a great high and when you feel the high you can put the foil down for later.If you inject and its too much you cant take it out.

    What are you asking here? Well, I know what you're asking, but what I really want to know is why. The way this question is posed is bothering me.

    In some ways, it seems like you are asking how to harm yourself. Instead of asking what is a safe dose, you have specifically asked us what dose might cause a first time user to OD. When posing questions such as these, it would be better to explain why you want to know rather than give us a one-line question.

    If you are asking how to harm yourself, or just as bad, someone else, we can't really handle either of those problems here on DF. If that is the case, the best we can do is redirect you to places that might be able to help.

    As for a safe, first-time dose of heroin... well... UTFSE. Here's a link: Complete List of Opiate Dosages. You will see the approximate amount for a first time user is 5-10mg for IV, 5-20mg for smoking. I would guess around the same as IVing for snorting. It depends on the purity, it depends on you. I would always ere on the lower side of things. These are, of course, only guidelines.

    As for an unsafe dose for a first time user, that also depends on you... but those guidelines are good. Any experience with doses outside of the recommended ones shown on that thread might begin going south. We don't know the quality of your H, though, so it's another one that's hard to tell.

    The simple fact of the matter is that when dealing with street-quality opiates, the range of purity can vary so wildly from batch to batch and different parts of the world that no one here or pretty much anywhere (other than someone who can hold the drug in his/her hand and TEST it) can provide you with a 100% conclusive answer.

    Hello ice, Welcome! I hope someone who knows more than SWIM answers your Q, it's very important for a first timer. SWIM will say that quality varies all over the planet, and that SWIY should start small and see how it affects you, OD's happen daily even from the long time users.

    Who will be with you this first time? If you don't feel comfortable with the dosage they suggest, please leave the situation immediately, your gut feeling is there for a reason.

    I won't preach on the dangers involved, you should know them already, be safe...knowledge is key!!

    I stumbled upon this thread because I'm watching a documentary on Iran's drug problem, and a guy said he was routinely shooting SEVEN GRAMS of heroin a day! And I'd imagine that stuff is as pure as you could get. I have no idea how that is even possible!

    Germany (yes, so many)
    With an unlimited supply of relatively pure dope you can easily go up to these amounts. It's not that opiates were *this* toxic - you only overdose when you don't have enough tolerance, so to say..

    It is nearly unbelieveabe how many receptor sites can be built up with growing amount of consumption.

    The other way round, getting OFF amounts of this size is not a walk in the park at all.

    Backintheday when I had a supply I needed not care about for one reason or another I used as much as three and a half gram of about 80% pure H #3.
    I had a sudden break in this supply, so I had to go onto methadone immediately- for the first two weeks I took a daily methadone dose of 240 mg only to hold me.
    I could reduce this very fast, by 10 mg per week until I reached 80 mg, then after maintaining for 3 months detoxed in a facility.

    So yes,
    Doses like these do actually exist - in very sophisticatedly addicted persons.

    Not to be tred out at home!

    Dude i would not suggest a first time heroin user to slam it. .10g CAN KILL you dude. You have no way of knowing how strong that bag is, so if your thinking of it be careful.

    Everyone only gets one life and it would suck for you to live your dash and end it with a foolish act of shooting up an unknown substance into your veins.

    It isn't uncommon for first time heroin users to sniff a couple lines, based on their previous experience with cocaine. Perhaps they will do some more since they do not immediately feel any affects (it takes 15-20 mins). They then OD. A matchhead would be substantially MORE than I would give someone if I were forced to inject an opiate naïve person. It is just far too risky to OD via IV with no tolerance. If you sniff it, only do a tiny amount (like a matchead) and wait 20-30 minutes until it has totally taken affect. Most important make sure someone else is present who isn't using so they can NARCAN you or call for help if you do OD.
