Been doing some digging through some obscure NOS/transcriptional changes lately, and I'm slowly finding why several studies have identified continued cell death for up to 2 weeks in rat models. What are possible implications of that? Well it would suggest that longer post loading for recreational users might be a good idea.
Could you post some links to the papers? I'd be interested to have a read.
I just noticed a couple of papers about modafinil protecting against meth toxicity, interesting.
