hi everyone, i'm barely 105 pounds and my drug history is nearly clean, i smoked weed a couple times and yesterday i rolled with a half pill for the first time and it made me hallucinate. also a bottle of beer makes me feel drunk. what i am trying to say is, i have a low tolerance. so. i am going to try injecting heroin, for the first time obviously. i know everyone is different but you now have an idea about my tolerance. how much heroin would be okay? and minimum how much heroin would make me od and maybe die? sorry if my english sucks, i am not a native speaker. thanks.
