Chromosomal abnormalities were significantly more frequent in leukocytes from LSD-25 users (six out of eight) than in nonuser controls (one out of nine). The two users without damage had the lowest estimated average dose. Damaged cells were observed in samples taken between 1 day and 6 months after the last dose.
