If everything keeps falling apart in Massachusetts, there won’t be a drug conviction left in the state. The eventual fallout from the 2012 conviction of drug lab technician Annie Dookhan was the reversal of nearly 21,000 drug convictions. Dookhan was an efficient drug lab worker — so efficient she often never performed the tests she was required to. The state moved much slower, dragging its feet notifying those possibly affected by Dookhan’s lab misconduct until a judge told it to stop screwing around. There still could be more reversed convictions on the way as the state continues to make its way through a 40,000-case backlog.
