@HiTwo @LukeAlmighty @kaosktrl For a while after every dose, it's not so shitty.
There are two routes that are pernicious though.
Social drug abuse: your friends are into something light, gradually get into heavier shit, and drag you into hell with them.
Doctor fucky wucky: You injured yourself, you were prescribed an opiate, you got addicted to the opiate your doctor prescribed for your pain, your prescription ran out, as a result of withdrawels your experiencing a lot of bodily pain, so you seek a replacement opiate under the assumption your injury still hurts, or just to stop the pain.
