Does this mean that the APD will hanging around one of the hot spots for a new crop of marijuana impaired drivers, Krispy Kreme in Anchorage?  On a serious note, does the APD have a sobriety test or a objective field test for marijuana impairment?  Has the State or City of Anchorage published allowable concentration of THC in a person's blood and how will this impact litigation of car accidents.  And for those who are drinking and smoking, will there be an algorithm to determine the combined effect.  I see nothing but problems with the determination of impairment.  Often the smell of alcohol on a person's breath is the trigger for a full sobriety test. Will they also target anyone who smells like they have been smoking marijuana the same way?
