If you're squeamish, look away now. This drug scene almost beats the dead baby scene in Trainspotting. Harry reveals to Tyrone his infected arm; and boy, does that vein look messed up. If the black infection around the hole where he shoots up heroin isn't enough, a close up of him sticking a syringe into it yet again is enough to make even the more stable of individuals want to vomit. It's a well known scene from the film, mainly because it's so hard to rid yourself of the image of that nasty infected arm after you've seen it. When he shows it a second time, it gets even worse, like a black and red mouldering disease all up his arm. It's Scary Because: no one should ever be so desperate as to do drugs in that kind of physical state. Or anything, in fact.
