So what? Even if this poster is trolling, these are questions that no doubt someone out there has on their mind, and so, in the interest of harm reduction, let's just go ahead and take the thread seriously and provide some serious feedback.
But there's not much to say really that hasn't already been said, so I'll just go ahead and reiterate these few points:
1. Heroin should not be the first opiate that one begins experimenting with. If, having been made aware of the risks (overdose, dependence, addiction and so on), one is still determined to experiment with opiates, then it would be in one's best interest to begin with the other, lower-caliber and pharmaceutical-grade opiates first: codeine, hydrocodone, eventually oxycodone, etc.
2. If, once again, having been made aware of the risks and after having some experience with opiates already, one is determined to give heroin a whirl, then it would be in one's best interest to stay away from intravenous use. I would recommend insufflation as one can and should begin by sniffing small, match-head sized bumps; effects can be felt in ~ten minutes time, and the user can re-dose as needed quickly, easily and, all things considered, safely.
3. If this is one's first time experimenting with heroin, then one should not use alone as, regardless of the ROA, there is always that possibility of falling out -- overdosing. It would be better to have someone there with a first-time user whom he or she trusts and who, at that time, abstains from using. (It wouldn't do anyone any good, of course, to have a friend too strung-out to be of any help should things go awry.)
