Being stoned is actually not a correct term for pot because you're stoned just as much as you're un-stoned after you smoke a hit. If that sounds confusing, you'll figure it out. But either way, you're still yourself. I think being stoned is just a barrier to hide behind that no one else sees. Remember, know one else sees it. You could be stoned, or just didn't sleep well. Best answer to are you stoned is "I didn't get any sleep last night."
