I have a rather unpleasant experience with addiction. I've inherited the addict gene from my father who has it from his father so i am a genuine full blown addict. That means that whatever addictive substance i contact in any way, i have much more chances to become addicted to it.
Like weed. I am addicted to weed currently, and i managed to keep my butt off MDMA and psilocybin after trying, i'm not into alcohol of any kind and i also smoke cigarettes, but in my condition i don't even count those.
I had a hard time with pharmaceutics, especially Alprazolam and those that end in -zepam.
I also developed some kind of sex addiction, as in if i don't get laid i get extreme mood swings. This works the same for the others too, but i can count more side effects of not using the formers, while lack of sex is just mood swings.
I see you guys don't quite know what addiction is to it's fullest extent, i'm not complaining about my life, neither am i criticizing you, i'm trying to raise awareness over this rather touchy subject.
