Think of a number, then add 50%
More than 700 drivers have been nabbed for drug-driving since a new law came into effect.
Figures released under the Official Information Act show 575 motorists were charged with drug-driving from when new legislation was introduced on November 1, 2009 to July this year.
During the same period, another 134 motorists were charged under older legislation.
That’s a 20-month period, which, as usual, makes no particular sense. We heard about 429 of the 575 motorists charged under the new law back in February. If that was for the first year (which makes sense given the lag in the current figures), the rate is going down. In fact, even if the 429 were through the end of January, which would be very fast data collection, the rate is still down, though not statistically significantly.

What does ‘charged under older legislation’ mean?

They don’t say, but my guess is that some people were charged with There is also an offence of driving or attempting to drive while under the influence of drink or drugs to the extent of being incapable of proper control of a motor vehicle, which is mentioned here and doesn’t seem to be added by the 2009 Amendment
