I agree. Pot helps you relax and also helps you to not overestimate your driving abilities while drunk. However, it makes you hungry. I find a juicy hamburger to do the best job... chunk of beef to satisfy the hunger, and some bread to help deal with that excess alcohol. Of course, the combination of alcohol, pot, and food makes me quite sleepy. I suggest hot coffee to keep you alert.
Therefore, I have concluded that when I drink and drive, I should always include a joint, hamburger, and steaming coffee just to be on the safe side.
I am still aware that even with the above precautions my driving abilities are reduced somewhat, and realize that the less time I am on the roads in that condition the safer both I am the public will be. For this reason, I always make it a point to drive as fast as I can when drinking, smoking pot, eating a burger, and handling a steaming cup of joe, so that I get where I'm going and off the road as soon as possible.
