Former DEA chief Peter Bensinger warned that full implementation of the marijuana legalization laws would “cause havoc” in the communities, schools and roads of Colorado and Washington state. “The highways would be littered with fatalities because you’re going to have increased use and marijuana stays in the body much longer than alcohol,”  http://www.bbc.co.uk/news/world-us-canada-21674166  “Most of these drug policy statements are about turf, which is really about budgets,” said director of the drug policy project at the Institute for Policy Studies. He said drug enforcement agencies were attempting to “maintain a monopoly on doctrine”. He said the federal government must be realistic about changing attitudes towards the drug, and he said that in states with medical marijuana laws in place, critics’ worst fears had not come to pass.
