I accept the Deputy's point but it is very difficult to make these comparisons. It is very hard and I understand what the Deputy is saying. For all other drugs, the position remains that the presence of a drug plus intoxication to the extent of being unable to control the vehicle is an offence already. Under the existing impairment offence section of the 2010 Act, section 5, the Medical Bureau of Road Safety, MBRS, tests for seven different classes of drugs, including opiates, cannabis, cocaine, amphetamines and others. It is very difficult at this stage to say exactly what the levels will be but what we are doing, unashamedly, is starting with the ones which we actually know are the most common drugs. We will look at how that works over the next few months or years and then consider other drugs.
