Currently there is no threshold lower limit which would indicate that a person had pot in his bloodstream, but it did not affect his driving ability. Currently anyone found with any detectible pot in his blood stream and involved in a serious traffic accident is considered under the influence. A change needs to made to make pot laws similar to what we have regarding alcohol legal limits. Scott Macdonald, Martinez - --- MAP posted-by: Jay Bergstrom
