It's not that it's a killer, it's that it is a destroyer of lives. Produces lots of 20ish year olds with deep pockmarks, no teeth, paranoia issues, Hep C, HIV, etc. Unemployable zombies with tendencies to shoplift, drive impaired, petty theft, etc. It's in the same category as crack cocaine. Very few functional serious users. Unlike, say alcohol, mdma, ectasy, benzodiazapines, marijuana, etc.

Meth really is a nasty business.
