There is “conclusive or substantial evidence” that marijuana or related compounds can effectively treat chronic pain, nausea caused by chemotherapy treatment for cancer, and spasticity caused by multiple sclerosis, according to a report published today by the National Academies of Sciences, Engineering, and Medicine. The report urges more research on both the benefits and risks of marijuana, but notes that researchers who want to study the drug face significant obstacles.

The recreational marijuana law that takes effect Thursday does not mention driving under the influence. It's one area where State House leaders say they expect to add some requirements next year.
But deciding what to require may be difficult, because there’s no established way to tell when a driver is impaired by marijuana.

On Nov. 8 voters in California, Maine, Massachusetts and Nevada approved ballot measures to legalize recreational cannabis. It is now legal in a total of eight states. And this creates potential problems for road safety. How do we determine who’s impaired and who’s not?
The effects of alcohol vary based on a person’s size and weight, metabolism rate, related food intake and the type and amount of beverage consumed. Even so, alcohol consumption produces fairly straightforward results: The more you drink, the worse you drive. Factors like body size and drinking experience can shift the correlation slightly, but the relationship is still pretty linear, enough to be able to confidently develop a blood alcohol content scale for legally determining drunk driving. Not so with marijuana.
