Currently if you have an auto accident involving injuries, alcohol testing is given to the drivers. The same is true with many industrial accidents. You can smell alcohol on your breath for a period of time, not so with marijuana, the smell dissipates long before the effects. Have you ever worked with a marijuana user? Until the responsibility and the ability to assign blame for drug use injuries and accidents can be readily determined, I must vote in favor of continuing the current policy. I know of no Tea Party, Republican, or Conservative who promotes environmental damage. I've never seen a business plan supporting environmental damage.
