Strange that the Mail make the claim, when the Govt website states
‘The government is unable to provide any guidance on what amounts of dosage would equate to being over the specified limits. There are too many variables, such as physical characteristics, where each person will metabolise the drug at different rates. Eating or drinking will also have an effect on the blood concentration’
Another fantastic piece of DM journalism designed to appeal to it’s ‘angry of tunbridge wells’ Readers mentality.
