That is really going to be intriguing to watch as they come up with testing equipment. I am trying to imagine where the cops are going to setup the checkpoints. Do you setup and check people as they leave concerts? Do you setup outside of bars and do a double check to see if they are intoxicated on two substances? Will the industry have access to the technology so you can get a self-tester? Imagine how weird that would feel. You smoke a bowl and then test yourself before you go out to drive to the headshop to check out the latest new gear.
