Cannabis and the peripheral nervous system
M DiBenedetto, HB McNamee, JC Kuehnle and JH Mendelson
The possible ill-effects of cannabis on the peripheral nervous system were
examined in 27 male subjects with respect to their motor and sensory nerve
conduction. They were classified by their previous cannabis use into casual
and heavy users. The nerve conduction studies were done after a baseline
period of five days and then repeated after a three-week period during
which the subjects could acquire and smoke standardized cannabis
cigarettes. The casual users smoked a mean of 54- 3 and the heavy users a
mean of 109-5 cigarettes during the smoking period. No deterioration of
peripheral nerve function could be demonstrated.
