Yes, please. I would like to know information equivilant to the science of the metabolism of alcohol.

We know , as a general rule, that alcohol takes 1 and 1/2 per hour per unit to metabolize. One unit being 1 ounce of liquor, 4/5 ounces of wine and 12 ounces of beer. Yes these amounts vary based on the ABV (alcohol by volume). But they are a good starting point.

So..... with this science we know that an average sized person will be impaired (in terms of driving) for 1 and 1/2 hours per drink. And people can figure out how many drinks is too many before they hit the .08 BAC in MD for impaired driving.

Are there any similar benchmarks for people to use using marijuana?

If there are not, how will people know when they are legally impacted in terms of driving? How can people make an informed choice?

I smell weed coming from other peoples cars literally every day driving around 695. How many of those people don't know that their judgement is impaired because they've never been taught when is too much.
