How much crystal meth would you have to smoke to overdose if I'm a 100 kg person?

What's your limit? Overdose, hmm...Depends what you consider acceptable. Let's assume that you'd rather not die from sudden cardiac arrest. So what's okay with you? Heart attack? Stroke? Coma? Kidney failure and lifelong dialysis or transplant? Paranoid psychosis? Seizures (possibly fatal)? Insomnia? Tooth rot? Boils on skin? You decide which are ok and which aren't and get back to me, and we'll talk about dose.
