The Daily Sentinel, 16 Nov 2012 – Now that Amendment 64 was passed by those who want to use or tax marijuana, we must consider the facts. I have practiced medicine in Colorado more than 28 years and will share a few highlights from the 117 medical texts and respected journal articles in my file. Marijuana makes most people artificially happy and relaxed for a few hours, but not without consequences. When under the influence, it’s hard to focus, think clearly or remember. It impairs judgment and delays reaction time. This impairment lasts much longer than the "high," making it unsafe to drive for over 24 hours after use. Users are two to seven times more likely to be involved in an accident.
