Hi everyone, I'm in no way saying it's ok to drink or drive whilst unfit due to drugs, but with new drugalyzer in the U.K. you could be over the limit from a spliff you had days ago. They look for such a small trace that being 2ng per ml of blood. The effects of the drug would of well warn off after two, three hours max but still you could lose your lisence days after consumption. All I would like is a guide as such they have done with alcohol purely for the safety of myself and others if I decide to have a smoke on a weekend. British government suck !
