This study doesn't seem to be very rational, it has meth at a "harm for others" score of 2 whereas tobacco and cannabis are at 15. Second-hand smoke is bad for people but I can't see why that'd be more of a danger than your average meth head. I think this chart that's linked on Wikipedia[0] that's from this study[1] is more accurate, alcohol is still near the top of the list but heroin, crack and meth are still higher.
