There is a very common sentiment among weed users that it doesnt really count as far as driving goes. Stoners will be repulsed and outraged by drunk drivers and then think nothing about going for a "blunt ride"

My friend group in college were heavy weed users, and generally all of them drove while high. I remember one saying he enjoyed it because he felt like he was driving a space ship. I asked if he still thought it was safe to drive, given that impression, and he said yes.

I drove high a few times when I was younger and I had to set my cruise control to 25mph to make sure I was going fast enough haha never again. I just use before bed now or occasionally during the day if I know I won't have to drive anywhere.

Even though their sentiment is wrong, I get why they would feel that way. Marginally drunk vs marginally high certainly feel* very different in how they would impact my own ability to drive.

That said, I don't do either. I also wouldn't take any amount of weed while working, but I'd feel comfortable having a beer during lunch if appropriate (work lunch/celebrate, e.g.).
