Coincidence or Cause?

Leonard J. Levick, MD; Stanley N. Levick, MD

JAMA. 1971;217(4):475-476.

Abstract
Two patients with testicular choriocarcinoma had taken lysergic acid diethylamide (LSD) for from 18 to 24 months continually; each averaged over "20 trips" before the tumor developed. LSD may be a factor in causing malignant tumors.
