Should illegal substance abusers be in Cabinet?

It was quite a relief to learn that Minister Varadkar refused an invitation from the staff of Our Lady of Lourdes Hospital to spend 12 hours on a hospital shift. For the editor of a Sunday newspaper to suggest that he should have done the shift incognito is rather disturbing. Would the editor like to be cared for in hospital by an incognito member of staff who had confessed to being an illegal substance abuser? Speaking to Hot Press on May 19, 2010, Leo Varadkar admitted he smoked cannabis in college, which is illegal.
In the early ’70s Charles Haughey was forced out of office by the then Taoiseach Jack Lynch because he was only suspected of being involved in criminal activity.
