The world is coming to realize that the infamous 5 ng/ml THC legal limit imposed by Colorado, Washington, and Montana are badly flawed. The marijuana lobby claims users can be unimpaired at levels higher than that. New research shows that drivers are impaired at levels well below that. This is a position we’ve taken for years, and welcome the fact that others agree.
Jacob Sullum, a pro-pot writer for Reason and Fortune magazines, is at it again.
This time, he claims that marijuana’s impact on crash risk has been greatly exaggerated, based upon Rogeberg and Elvik’s (R&E) paper, soon to be published in the journal Addiction. Sullum, in his typical snarky style, writes that there’s not much evidence of a surge in traffic fatalities due to marijuana-impairment in Colorado or Washington.

Hartman et al. … READ MORE
Noelle Phillips and Elizabeth Hernandez got some things right in their Denver Post article, “State still not sure whether legal pot made roads less safe.” The article was generally well done and reasonably accurate.
Colorado’s DUI law, which has a single definition of DUI irrespective of cause was correctly cited as a prime reason that Colorado is woefully behind in attempting to understand the impact of marijuana on road safety. If you find yourself … READ MORE
Forbes Magazine has joined the Denver Post, the Los Angeles Times and other rags that spread misinformation about drugged driving. Jacob Sullum’s Colorado’s Prosecutors Complain They Have To Prove DUID Defendants Were Actually Impaired was the most recent in his series of inept DUID reports published by Forbes.
Sullum, like many others, confuses the misdemeanors DUI and DUI per se. Although they may carry identical sentences, they are distinct charges. Proof of impairment … READ MORE
