It's a little bit of both, but if you do look at the labels of the drugs prescribed now, it says to avoid operating heavy machinery. I would include a car as heavy machinery. When we talk about education and labelling on any drug that can affect a person's cognitive ability or ability to drive, it should be very specific.
That's where education comes in for the physician or prescriber that prescribes it, like your dentist and/or pharmacist. That's where they can come in and say, “By the way, you shouldn't be driving with these, and especially when you have that combination of opiates and alcohol.” That increases the risk.
