First time trying H. After effects. Is this road to addiction?

I am a try everything one time kinda guy. I had a chance to try best H possible to find few days ago and now 3 day later I am feeling that I am missing something in my life that many things that used to matter are not important anymore. Is this how addiction starts? I tried few opiates before but never felt this way before. People who felt the same i would really appreciate your input
