A significant increase of chromosomal abnormalities was found in leukocytes from LSD-25 users (six out of eight) compared to nonuser controls (one out of nine). The two LSD-25 users showing no damage reported the lowest estimated average dose. The subjects whose cells showed damage were tested between 1 day and 6 months after their last LSD-25 dose.
与未使用LSD-25的对照组(9人中有1人)相比,在使用LSD-25的使用者的白细胞中发现染色体异常显著增加(8人中有6人)。两名未显示损伤的LSD-25使用者报告的估计平均剂量最低。细胞显示有损伤的受试者在最后一次服用LSD-25后的1天至6个月之间接受了检测。
