The information collected centrally on prosecutions under section 5(i) of the Road Traffic Act 1972 does not distinguish offences of driving whilst unfit through drugs from those of driving whilst unfit through alcohol. The latest available figures relating to the total number of prosecutions for driving etc. after consuming alcohol or taking drugs are given in tables 1, 4, 6 and 17 of "Offences relating to motor vehicles, England and Wales 1979", Cmnd. 8087.
