Entrepreneurs Sean Sheridan and Chris Elkins are preparing to open the World's First Marijuana Mall in Trinidad, Colorado. They have high expectations for the 5 dispensaries they plan to bring in: "If they're not doing $5 million a year, then we're not driving enough traffic," Sheridan said. But the important question we should be asking is: How about people going to get home? Driving after Smoking Marijuana Ride-sharing companies will play an important role in making your next trip to the pot mall even safer & more enjoyable. As part of their " Drive High, Get a DUI " campaign, the CDOT even suggests using Uber and Lyft. Here's a worrying trend: The CDOT reports that since marijuana use became legal in January 2014, the percent of drivers involved in fatal accidents who tested positive for marijuana has increased from 4.7% in 2012 to 12% in 2014. Is there a DUI for Smoking Marijuana and Driving in Colorado? We spoke with Attorney Jay Tiftickjian, an expert in Colorado marijuana dui law, and here's what you need to know: From a legal perspective, drinking and smoking pot are treated the same if your ability to operate a motor vehicle is impaired - even to the slightest degree. There's actually a legal term for driving while high in Colorado: DUI-D (driving under the influence of drugs) and there are other terms to understand, like DUI and DWAI . How much marijuana can I use and then drive? With drinking alcohol and driving, your blood alcohol content is easily determined when you submit to a blood test (check out this BAC Calculator ). With marijuana, however, the law states "Colorado also has an inference of impairment with a blood test of 5 nano grams or more of active THC." So the officers must determine if you are 'impaired' while driving in order to request that you submit to a blood test to determine the level of active THC in your system. Here are some Do's and Don'ts if you get pulled over . What's the bottom line? The current law allows those charged with driving under the influence to try and prove they weren't actually impaired, even if they tested above the 5-nanogram limit. As it turns out, some drivers who have faced DUI-D or DWAI for marijuana impairment in court have had their charges reduced and, in some cases, even dropped.
