I’ve been using heroin for four years now. I have noticed, when I use other drugs now, drugs that I used to enjoy before I started using heroin, I don’t enjoy them anymore? I can’t even smoke pot anymore...I don’t like the way it makes me feel. This is the case for pretty much everything besides heroin for me. I have a friend who uses heroin as well who says the same thing. I’m wondering, have other heroin users noticed this as well? Why is it? My theory is: my brain chemistry has been changed from the prolonged heroin use, and other drugs affect me differently now. Let me know what y’all think!
