The drug testing thread got me wondering

No they don't. Even if they did, it wouldn't affect a driver being taken off the road while under the influence of said drug.

Nyquil....is exempt. But you're not allowed to drive while under the influence of ANY drug that may affect your ability to drive....legal or not, over the counter or not. If you're involved in an accident, you'll be held responsible. And quiet possibly, criminally responsible.

 

Take it from me. Medical Mary Jane and a driver won't happen as it's mainly cancer patients that use pot and as I will tell you from my experience of going through 35 radiation and 6 chemo treatments they won't be driving! At least NOT a truck! I even had a script for medical pot but could not fill it in MO as it wasn't legal!

But most of us who took a lot of radiation don't feel like climbing up into a truck or feel like driving for any amount of time except to ride the bike but to much physical labor and driving when your blood count is down and tired from being poisoned by chemo and radiation just pulls the life right out of you! I even gave up riding the bike when I dropped it when I pulled in the parking spot at the hospital going in for a daily shot of gamma rays! That was embarrassing not to mention a PINA trying to pick that cruiser up off the ground!

So I wouldn't worry to much about "a whole bunch of drivers" driving high and I do believe the rules say " under the influence" and pot even when in "medical" form will get you "high" and I haven't seen where there is an exception to smoke it even with a doctors prescription and have to pass a DOT pee pee test! This is a question for log lady or Diesel Bear to answer.

Good Luck

The prohibition with regards to the use of marijuana actually extends beyond those who are driving under the influence.

Because commercial drivers are subject to the drug testing requirements contained in Part 382 & Part 40
and
Because Marijuana is one of the substances for which Part 40 specifies screening
and
Because marijuana is still listed as a schedule 1 substance (no recognized medical use) by the federal government, regardless of what is permitted by a state statute.
What all of this means is not only may a commercial driver not drive while under the influence of marijuana...it's use is prohibited.
