Comparing pot's effects to alcohol is apples and oranges. The effects of alcohol leave the body when the alcohol is gone (or soon after). The effects of pot most assuredly do not. Consider this the next time you're returning from vacation on a late-night flight: The air traffic controller has returned from days off, during which time he can use weed as he wishes. It's a quiet night, and he sits back, all mellow and relaxed, then starts issuing instructions to the wrong aircraft. This is but one possibility. Think about jobs such as an oil worker on the floor of a drilling rig, or a highrise construction worker - or your surgeon poised over your brain with a scalpel.
