IF YOU ARE HIGH, DON’T DRIVE
Driving under the influence of marijuana is an evolving subject of concern to safety experts and law enforcement. Last week I wrote about the difficulties California and other states are having establishing at what levels marijuana use presents a driving risk and how those risks are assessed. There is yet to be a consensus. This has happened before. In the 1930’s and 40’s as automobile ownership reached the masses, there was no general agreement among the states regarding drunken driving and until the 1950’s no reliable way to measure a driver’s level of inebriation. Before the advent of the breathalyzer, whether someone was too drunk to be on the road was left to the subjective decision of law enforcement and all too often, that mean the officer would just follow the driver home to make sure he or she made it home safely.
With the legalization of marijuana, we face similar dilemmas, and just like the early days when drunken driving laws were evolving, there is yet to be a reliable method to test a driver for marijuana testing and there is no agreed-upon limit where THC levels are considered too high to drive. In the mid-twentieth century, there were honest debates about whether a moderately intoxicated driver was dangerous and most states, even up to the late 1960’s, did not prosecute a driver if his or her BAC was under 0.15%. Statistical analysis and scientific studies later established that a BAC over 0.08% makes a driver dangerous and the trend is going lower, towards a 0.05% BAC threshold.
