Who is more responsible? A person driving after smoking joints or a driver under the influence of alcohol. The answer is neither. Driving under the influence (DUI) of both drugs and alcohol can be very dangerous. That is why every country willing to legalize marijuana for non-medical purposes should strictly regulate using cannabis while driving as a serious offense. Most states have no tolerance for driving high, but two out of five US countries have already made regulations. In Colorado, for example, it is allowed to drive with THC level up to 5 nanograms per milliliter of blood. While Canada is still in a long process of legalizing marijuana, using the substance is still illegal, as well as driving after using it. This infographic provides information on what defines driving under the influence of alcohol and drugs and how it differs from driving while intoxicated and compares the laws in both Canada and the USA.
