§ Mr. Jamieson
I have been asked to reply.
National road accident statistics do not identify cases where drivers involved in fatal road accidents were under the influence of drugs. There are no estimates of the numbers involved in accidents where drivers had been under the influence of cannabis. Recent research shows 404W that 12 per cent. of those killed in road accidents had traces of cannabis in the body. However, the presence of the drug cannot be taken as evidence of accident causation. In addition, the inactive element of cannabis remains detectable for a long time after any impairing effect.
