Can brains bounce back after meth?

Cohen Irwin is a face of a pilot study in New Zealand that works with meth users to map the effects of the drug on their brains – and to trace signs of healing and rehabilitation in the brains of those that quit. “If like me you’ve been smoking meth for years, this is the place to be… Meth is death,” he said. He also hopes the research will help him stay abstinent.
