Is your NYC cab driver on drugs?

New York City taxi drivers have been caught using marijuana and cocaine at rates double what they were last year, according to new research.

The New York Post reports that 51 cabbies lost their license to operate taxis last year because of drug use, which tops 20 in 2012 and 34 in 2011.

Since 2010, the Taxi and Limousine Commission has penalized 167 drivers for substance abuse.

“While the number of positive drug tests is statistically incredibly small, we take our responsibility to public safety seriously to the extent that we would continue to be as vigilant even if a single applicant were to test positive,” TLC spokesman Allan Fromberg said.
