A single tab usually contains between 30 - 100 ug of LSD
"For those concerned about immediate medical hazards in ingesting LSD...Abram Hoffer has estimated, on the basis of animal studies, that the half-lethal human dose--meaning half would die--would be about 14,000 [ug]. But one person who took 40,000 ug survived. In the only case of death reportedly caused by overdose (Journal of the Kentucky Medical Association), the quantity of LSD in the blood indicated that 320,000 ug had been injected intravenously."
