Your memory is shot from your days of smoking.
You said "That's why they tend to not drive too fast where any of that stuff impedes their driving." So there is some speed where someone high suddenly becomes impaired?
Also you have claimed slowing down helps potheads drive better. But according to you, potheads aren't impaired, so why the need to slow down?
You head is firmly impanted on this one, pothead.
This is why I hesitated to mention my own use, because people like you are incapable of providing your opinion without putting some sort of slur at the end of it. Not that your reasoning abilities are very impressive in the first place, so I do understand why you have to resort to it.
