Pueblo Chieftain, 16 Dec 2012 – Most of the discussions I have read about the legal ramifications of the passage of Amendment 64 seem to revolve around the level of intoxication as it relates to marijuana usage in the education setting, drugged driving, amount in possession and other criminal issues. However, I believe that a significant issue that is being overlooked is the matter of civil liability that could confront a business owner because of marijuana’s characteristic of being detectable up to 72 hours after usage.
