Snorted heroin is most definitely enjoyable, but how practical snorting the drug is depends on what form you are getting it in. #4 heroin is great for snorting, it is usually an off white to white powder but can be slightly brown or grey as well, the East coast of the US tends to get good #4, I am pretty sure Canada does and in Australia and most of South East Asia this is the common type of heroin. As someone who lives in Australia who has used quite a bit of #4 heroin, my favourite ROA for heroin is snorting and I find it to be much more effective and economical than smoking it.
#2 or base heroin, which is prevalent in Europe and presumably in Western Asia where it is typically manufactured, I would guess at the least it is quite common in North Africa wherever there is a heroin market, and quite probably whole of Africa, however, Africa is one Continent where I honestly know nothing about the heroin scene whatsoever. Base heroin is not water soluble, injecting drug users typically add an acid to the solution they plan to inject to get the heroin to dissolve properly. When you snort something, it becomes a liquid in your nose and is absorbed via the mucous membrane, as I understand it, this typically makes snorting non water soluble drugs less effective than snorting water soluble drugs. In the case of #2 heroin I am fairly certain smoking would be generally considered a more effective route of administration than snorting.
As Blind Melon mentioned, the West coast of the US tends to get tar heroin, this is not exactly the same as either #2 or #4 but is more similar to #2 in that it is harder to break down in solution and smoking would typically be considered a more effective way of using it than snorting. I believe that heat and agitation are how most users break down tar into a solution and the addition of an acid is not necessary. Blind Melons method of making a heroin solution to use nasally is probably the most effective way to snort base or tar heroin, a good idea might be to put the solution inside a nasal spray bottle that you rinse out so that each spray gives you a fairly similar dose, that way you can slowly titrate your dose to a level you feel good.
If you are opiate naive expect to get quite nauseous and itchy, you might consider taking an anti histamine to reduce those side effects. If you elect to do so and end up using a first gen anti histamine (doxylamine, promethazine, diphenhydramine are a few) you should use a lower dose of heroin as that will add to the sedation and a lower dose of heroin may lead to fatal respiratory depression. I find the itch and nausea to be less with heroin than any other common opiate, but it is still very much there when you are not used to taking it.
I wont harp on about the potential for addiction or how dangerous heroin is, I am sure you are smart enough to be aware of both when you are coming to Bluelight to ask for advice. Do start small and work your way up, you should probably take about 10-25mg (depending on bodyweight and opiate tolerance) every 20 minutes or so until you start to feel good. Bear in mind the effect doesn't peak straight away so if you are looking to get fucked up don't keep snorting until you start to nod, when you start to feel good and want to nod go chill out somewhere and put on some good chilling tunes, make sure the dope is nearby for if you need a little more and smoke some cigs and/or weed if you are into that sort of thing, ciggies kick my ass on opiates and despite the fact I can rarely finish them and it makes me feel quite ill I usually do smoke them because I find it really pleasurable and when I get the headspin it really adds to the opioid sedation.
