thanks for bumping my thread, i can't believe i couldn't find cannabis when i posted it. i looked, i thought "THC has to be included", whatever...
i would put alcohol and tobacco higher in both categories. cocaine and heroin lower...
i couldn't quit drinking if i tried but i came off heroin and coke fine, both cold turkey with only a deviate septum to show for it. my liver is a testament to how harmful alcohol is.
