Having tried Heroin and having a unique brain chemistry when I did try Heroin I snorted it and became energized, no nod or laying down and floating. My wife got addicted when she was young and she went cold turkey and got off it but it was hell for weeks. She IV'd, I was always curious as a fan of opiates, so when I got offered it I talked it over with my wife, she veined it and fell back onto the bed, I snorted and got totally "up" and was walking around outside just enjoying the euphoria, stopped at a local bar/restaurant where I knew the bartender I don't drink so I ordered coffee and the only thing she noticed was that I seemed in a great mood that day.
Shooting it once I didn't get the typical response you see in movies or what I saw with my wife, she never did it but that one time (after having been addicted as a younger woman) and gave me the rest of it and never touched it again. I did skin pop and the response was similar to snorting and I didn't like the process of heating it in a spoon and filtering it through cotton for the same effect I got from snorting. I needed very little to get a high that lasted several hours, unlike blow where it was like intense high than fast come down and craving more.
I only did it for a while maybe twice a week then told my dealer to stop contacting me as I knew I liked it too much. Knowing my propensity to abuse something that did more to help my mental health issues that have never been properly treated or diagnosed was very likely to become a daily habit if I continued so I just stopped. I heard what my wife went through when she got off it many years ago and I didn't want to go through that and feared I wouldn't be able to get over it. If I had the typical response to the drug like most people I've talked to where they zombify and can't actually function and just lay down and float away in their mind I would never recommend that to anyone. For me it was mostly a pretty awesome experience, no psychiatric drug ever made me function so well, in fact those psychiatric drugs were a nightmare, unfortunately H isn't something I could use because eventually it would become an addiction that would kill me. But hell I enjoyed the little bit and the short time I snorted it.
