This tendency in our volunteers, to persevere even under the possibility of an annihilating psychedelic experience, was marked. It was most apparent during our tolerance study, which took place the next year, in 1991, in which volunteers received four large doses of DMT, each separated by only 30 minutes. Not one volunteer, no matter how worn out, refused that fourth and final high dose of DMT.
