WASHINGTON (AP) -- Amid all the debates on Capitol Hill, lawmakers are also wondering whether driving cars after smoking marijuana is dangerous.
Among the unanswered questions is: Would drivers who are `high' travel too fast or too slow for safety?
Congressman John Mica, a Florida Republican, convened a hearing Thursday of a Transportation subcommittee. He says he's worried that growing numbers of drivers are impaired, increasingly with a mix of drugs and alcohol. But he says it's nearly impossible to gauge the danger. Unlike with alcohol, there there's no way to quickly test drivers.
Congressman Gerald Connolly, a Virginia Democrat, says it's just as possible that pot doesn't pose as much a risk as alcohol. He says drivers who are high on marijuana may even drive slower.
