Heroin of any kind usually doesn't have the effects of insomnia(staying up all night not being able to sleep) or appetite suppression unless they were mixing it with some kind of stimulant like coke, meth, or amphetamine that is called speedballing which to me is what that sounds like. Every time I have sniffed ECP dope, it made me super sedated, nodding out for hours, and always helped me fall asleep that is how it makes the majority of people feel. Sniffing dope isn't more "mind blowing" than smoking it, it just has a different kind of feeling, and usually lasts longer than smoking it, probably wont give you the same kind of rush, although there is a rush with sniffing it isn't as quick to come on as smoking it. And if its brown powder H, it can be shot just mixing it with water. unless its that base heroin they get in some European countries which needs to be broken down with citric acid to be slammed, as it is almost like heroin in "crack" form, and is really just meant to be smoked. But most heroin can just be mixed with just water and shot, the brown powder dope your taking about is proabably either "gun powder" which is a dark brown color and is most common in the western US/Rocky mountain states. Or if its more of a beige/tan/light brown color its east coast powder or ECP dope, which is more common in the east coast states and some of the mid west. Both of them can be mixed with water and shot, but if you haven't ever done this, don't start as you will never want to do dope any other way again. Once you inject heroin, you are basically only going to like doing it that way because the rush is so much stronger than any other ROA. Just stick with sniffing or smoking it if you can. Be safe!
