Firstly I would like to apologise if this is not correct place to ask this question, as it can be seen more as chemistry and not biology question.
I was looking around for data on psychedelic substance called
25i (25I-NBOMe) . It was fist synthesized in 2003 and is somewhat 'new'. I have found some data on overdoses and they are few, however I could not find any specific data on mortality to dose rate nor on LD50 (Dose where 50% of people would die). Wikipedia is quiet in this regard.
Judging by the dosage it being active in sub-milligram doses (600–1,200 µg) it should not be very lethal compared to most, should it?
Where could I get data on LD50 for
