I am a 21 year old female who is interested in using heroin just once (I know that is what all heroin addicts say before they start abusing heroin, but honestly I just want to try it once). I do not have an addictive personality, I smoked cigarettes for 8 months but have quit for 2 months now and don’t miss it. I do smoke weed, do mushrooms occasionally and have tried cocaine a few times, but do not have urges to do drugs at all. I can do mushrooms everyday for 2 weeks and then just stop and not do them for years. With this background information on me, could I expect heroin to not affect me as much as some people addiction wise. I am just wondering about the addictive factors of heroin in non-addictive personality people.
