.....Just one quick question...How did you record clearly and precisely the differences between drugs and alcohol if you were under the influence of these 2 drugs anyways. If a second person would have witnessed you driving under the 2 effects, it would have been more accurate in my opinion.
To answer your question, I want to first point out that I have not driven completely drunk, but maybe over the legal limit for driving purposes. At this level of impairment, I am still able to speak with coherent sentences and can walk in a reasonably straight line. I've also noticed that I'm way better at playing online shooter games at this level of alcohol impairment(headshots all the damn time). However, I've made self evaluations regarding my mood while driving as well as my confidence level.

I am much more confident after a few drinks and I have a personal sense of 'heightened awareness'. I've found that my actions reflect on these feelings and I start to act carelessly, which I regretted later after I've thought about what could have happened in that 5 mile drive, had I done what I did while there were other drivers around me.

Second, I have driven home, high, once when I feel I probably should have waited another hour. While driving I felt very self-conscious and paranoid that I might make a mistake so I would constantly check my mirrors, speed, as well as keep an eye on other drivers so that I was never tailgating or in a person's way. I was able to make it home from the 40 mile drive and I would take that drive over the one 5 miles long being impaired through alcohol.

These are personal evaluations that I feel are accurate as I have had time to reflect on them while sober. I do not learn most of my lessons this way, as I take the hard road many times and learn from first hand experience, but I am glad that I was able to learn from this without harm done to anybody(except maybe my liver).

I understand that not everybody has the ability to assess themselves or function the same way at the same level of impairment, which is why I definitely do not condone driving under the influence of anything. But if it had to be ANYTHING, I would prefer a stoned driver over a drunk driver any day.
