I saw last week in a washington state news paper a mention of a study that showed 18-20 nanograms was about the same as .08 alcohol.So where do they come up with 5?

We also already have laws on the books for driving while impaired.The only thing setting this kind of limit would do is give cops anouther way to screw you and your rights

And here it is...HB11-1261 - the THC Level DUI Bill This is the first sentence of the bill: "The bill allows a person who drives with a tetrahydrocannabinols (THC) blood content of 5 nanograms or more to be charged with DUI per se." Considering the information about THC and driving out there, and the lack of a problem with drivers using cannabis, this surprises me. How did they determine the 5 nanogram benchmark? Rating: 5
