Yeah I can, too.
But I think the point squidhead is trying to make is that we shouldn't. Familiy life is definetly more important if kids are involved, IMO.
Driving/working high is, although definetly possible, not something I would advise. Although I consider myself a better driver when high, just because I'm more at ease and keep a lower speed.
This is because there are other people on the road/at work. And if something happens to one of them, and you're involved (not plain in fault but just involved), then we have this urge in our society to look for consiousness-altering substances and we tend to blame the drug user. I don't appreciate this fact but it is what it is. When you drive a car on a public road, there's like this "contract". I don't have children (and I'm assuming you don't either) but I can imagine that if I did I would *never* drive high when they're in the car, and probably never again. This is because you have a responsibility at that point for another creature. I do believe we are all One and since everyone is connected, it would be foolish to be random in who we are protecting. The responsibility you have over your own children should be carried on to the rest of society.
Not that I want you to stop driving high, just don't blame "the system" when you get caught

edit: OT: No. I do know someone who stopped because he didn't like how unmotivated it made him. But yeah, he just stopped, so..
