I'm going to be honest heroin is a bad deal. I know a lot of people in family who used to sound just like you. "I know it's addictive but I just want to try it." But the thing is, its a great drug and after you've done it everything else just seems dull. So you wont get physically addicted until youve done it quite a few times but you can get mentally addicted very quickly, which leads to a physical addiction. Its just not a good road to go down when theres so much better stuff out there for you.
