While more drivers have admitted to using marijuana, previous studies about its impact on driving performance have been inconclusive, the institute said.

"In other words, it found a slightly increased risk of collisions in states that have made marijuana legal for adults, but it did not actually look at the causes of accidents and does not show marijuana is to blame for that increase", according to Tvert.

More cases of automobile crashes have been reported among states where marijuana has been legalized, according to a first-of-a-kind study conducted by an insurance institute. "HLDI's findings on the early experience of Colorado, Oregon and Washington should give other states eyeing legalization pause". The group, known for publishing insurance loss statistics, says it has found a link between legalized pot and a surge in auto accidents.

"We're concerned about what we're seeing", Matt Moore of the Highway Loss Data Institute told CNBC.

Trade group Cannabis Business Alliance didn't mince words in its criticism of the Highway Loss Data Institute study, claiming that it was "just another attempt to incite reefer madness".

The study revealed more drivers involved in crashes are admitting to using marijuana.
