title: Pattern and reasons for substance use among long-distance commercial drivers in a Nigerian city.
abstract: OBJECTIVE
  To determine the pattern and reasons for psychoactive substance use by long-distance commercial vehicle drivers in a Nigerian city.
  
  
  METHODS
  All licensed long-distance commercial vehicle drivers who travel a distance of at least 500 km from the city metropolis were recruited. Each fourth consecutive driver who was to load his vehicle for the day was interviewed at the 10 long-distance motor parks. They responded to a sociodemographic and semi-structured pro forma requesting the type of drug used and the reason and pattern of use. The data obtained were analyzed by means of descriptive statistics using the statistical package for social sciences (SPSS) version 16.
  
  
  RESULTS
  All the respondents were males with a mean age of 43.4 years. There was no statistically significant difference between the mean age of substance users and nonusers (t = 0.491, P = 0.853). The reasons given for drug use were to keep awake while driving, for pleasure, as part of the culture, peer influence, as a substitute for food and for no obvious reason. The pattern of use tended to be related to the reason given for the use.
  
  
  CONCLUSIONS
  The reason for drug use in long-distance drivers could be used to modify the pattern of use to minimize the risk associated with drugged driving.
