Meth users tend to lead messy lives with lasting effects that linger long after they leave.

For every pound of meth produced, five to seven pounds of chemical waste is left behind. Those residues can cause a litany of health problems, including breathing issues, skin irritation, headaches, nausea and dizziness. Over a long period, liver and kidney damage, neurological problems, and increased risk of cancer can occur, according to the Minnesota Department of Health.
