There were fears that the legalization of cannabis will increase the rate of DUIs. It’s good to know that ten years later, those fears are yet to be validated. It is a very bad idea to drive under the influence of cannabis even in states where cannabis use is legal. Thankfully so far in Colorado, alcohol remains the major driver of DUIs and not cannabis as once feared. Teenage use of cannabis was also a major talking point that sparked fears before the legalization of recreational marijuana use. Ten years after legalization, data shows that the percentage of minors using cannabis has risen by 4 percent during that period.
