I was watching a movie called "High Life" where the main characters are morphine junkies who crush pink morphine pills and shoot it intramuscularly. One the characters says, "Morphine isn't a street drug like heroin, you don't have to mess with your veins, you can shoot it into any muscle on your body" before shooting it into his leg. My question is, how effective of a ROA is this? I'm an IV heroin user and i would imagine that you wouldn't get a rush from it therefore it wouldn't be as good as IV. Any opinions on this?
