Three epidemiologic studies in developing countries have failed to find definite evidence of impairment among heavy users of cannabis, but field studies may lack sensitivity. Experimental studies in which subjects have smoked heavily for varying periods have shown a lower serum testosterone level in men and airway narrowing. Reports of effects on immune mechanisms, chromosomes, and cell metabolism are often contradictory. Effects on the fetus are still uncertain.

Clinical research has been limited to epidemiologic and retrospective studies. In some reports, cannabis use has been correlated with low birth weight, prematurity, intrauterine growth retardation, presence of congenital abnormalities, perinatal death and delayed time for the onset of respiration (for a review see Park et al. 2004).

There is an abxmdance of evidence to indicate a significant involvement of marijuana in crash victims. For example. Crouch et al (1993) analyzed all truck crashes with fatally injured drivers in 8 U.S. states over the eourse of one year and foimd cannabinoids (without alcohol) in 13 percent of the drivers. Ward and Dye (1999) summarized the results of 20 epidemiological studies of cannabis involvement in crashes and found that, depending on the study, cannabis...
