Regarding drug detection, many people take medicines or use cannabis oils, ointments and so on, for example. I am thinking of the slick barrister – we have a few of them in Leinster House – who can talk his or her way around that. I am not referring to anyone on this committee, thankfully. Has the Garda gone through enough prosecution cases yet to be able to determine where the difficulties arise?
