For me, I was a marijuana user at the time and hadn't been able to get any for several weeks. A family member who was a heroin user had some on him the one day and he offered. He wasn't sure if I had ever done it before or not. I was reluctant at first but I already knew the dangers and I already knew that I would never ever do it again so I tried it. I don't regret doing so because I didn't like it, it was disgusting. I would never, however, even consider injecting any king of drug ever. I think that whenever someone is even slightly tempted to inject anything into their body, they have hit rock bottom.
