This makes sense. I'm not disputing weed causes impairment. Depending on the weed and THC level, however, and if you're not a complete dope, THESE DAYS people have an awareness so they do not drive. Drunks seem to lack that form of higher consciousness. Medical marij. will take away some of that impairment because of the lower THC level.once cannabis is legal.... we will have plenty enough to prove that they are as dangerous as alcohol and should be treated as alcohol for DUI. it's clear and definite - cannabis does cause impairment. period.
Someone quoted a source as WebMD and to me, they're pretty useless and like other commercial websites, you can't depend on the accuracy of their information. I worked for an online and offline publishing company. Our experts were pretty much a joke but the customers trusted the online and offline mags.
As you read through all this keep in mind how many people are also taking benzodiazipams (ativan, geesh I can't remember the names of the others but I do mean, "Valley of the Dolls," prescriptions) and they are driving. Simple tests and pretty cheap.
