N2  - This paper comments on the paper, "The Contribution of Drugs to Motor Vehicle Crashes and Injuries," by Bierness, Simpson and Williams. The authors concluded that there was inconsistent evidence of the risk associated with drug use while driving, with disagreements both among the epidemiological studies and with results obtained from experimental studies. The paper suggested that the inconsistencies may be due to methodological problems or lapses in the existing studies. Mentioned were several methodological problems. The discussion in this paper on methodological problems agrees with the Bierness, et al., opinion that methodological problems represent a major barrier to obtaining scientifically consistent results from the different studies. However, it is pointed out that some of the problem in obtaining consistent results studies may be due to intrinsic factors, that is, factors that at this point there are no means of overcoming and thereby reducing the variability of results.<p />
