No from a few papers I read on the ld50 and case studies and such. I found 6.4-50 mg/kg to be lethal it also says that 2-10 grams is lethal in humans not 2-10mg but from some reports there was multiple times where someone would recover from a higher dose sometimes double or more this is also based on the oral toxicity level. Remember it's also based on weight, age, and etc. I got some of the information from this file.
