Can you drive after smoking weed?

Isn't that a dui? I was working on my boat trailer today in the boat ramp parking lot because, well the boat has to be off of the trailer to do this. Anyways, this dude rolls up in a late model corvette and I smell marijuana from his car because it was a convertible. I keep on working and he starts driving around and stopping at different spots in the parking lot, getting out of the car etc. Anyways, after 20 minutes or this I look over and this dude is looking up at the sun making picture frame gestures with his hands with a big ass smile on his face, lmao. He's high as a kite at this point, maybe that's what he thought he was doing, was flying a kite. lol Anyways, can you still drive in that condition? There's a reason why I don't smoke weed.
