Only slightly hyperbolic. As someone who's spent more time than he'd care to admit in East Texas (a major manufacturing and distribution center for illegal meth), people that make this stuff do it in their homes, and eventually tweak out and blow up the neighborhood. It happens a lot more than you'd think...
... not to mention, habitual usage doesn't exactly lead to safe behavior, which is inflicted on others.
I'm not a drug regulation advocate, but it's important not to paint Meth as a victimless drug. The first target may be yourself when you use it, but the collateral damage is not insubstantial.
A better analogy than a rocket launcher might be hand grenades, if we're sticking to small armaments as the analogy.
