I was always wondering how on earth anyone can do 0.5 g of meth a day. I mean that stuff is sooo potent. I find already something around 50 mg in one day extreme, my memory goes out the window and I start hallucinating. My brain is easily overexcited, I guess?
Anyway, oral administration might be a way to control it. Its bioavailability po is good and peaks in blood are reached after a time similar to snorting. I think 2 hours. If it is only about the kick it might be hard to control meth as you'll reach neurotoxic levels due to the long half-live (0.5 g, wtf?


) and your brain will not be able to control its own dopamine without meth for a while after your last dose. So less might be more?
