IAM director of policy and research Neil Greig said: "The IAM can welcome this report as the biggest step forward in the drug driving debate since drugs first started to feature in crashes."  

"Setting limits based on a drug's effect on driving opens up a whole new approach to enforcement and sends a very strong message that it is unacceptable to have drugs in your system behind the wheel. The IAM is also very encouraged by the panel's finding that drugs mixed with alcohol are an extra danger and the setting of lower limits when alcohol is present is very good approach. We also support the panel's finding that more research is needed such as routine blood sampling at road traffic crashes to quantify the exact level of drug driving. 

This is a complex issue and awareness raising campaigns for drivers, patients and the medical profession must be a top priority."
