Small anecdote regarding how addiction works: I took ecstasy on this new year's eve together with my brothers and it felt amazing. It felt like my mind was free and I was way faster at phrasing my mind. Few hours later I went to the bank, got a few hundred euros and tried asking the dealer for a hundred tablets. That's how crazy ecstasy was for me. I am 100% sure if I would try heroine once I would fall for it, especially because as a tech guy I have the means to sustain it to a deadly degree.
