Breathalyzer...I hope there's a throw-away component The other day I was walking past two construction workers who appeared to be taking a break and sucking on weed. As I approached, they tried to hide their smokes. I commented, "smells like quality sh*t". They laughed, relaxed, and resumed. The weed they were smoking was LIKELY NOT medicinal. ....They are working on a building over 6 stories high and growing taller. Lots of heavy equipment, dangerous heights, and plenty of dangerous tools. Tall buildings or not, every workplace presents dangers. I presume every employer would want to restrict any employee who was stoned. Just imagine, if every employee and visitor had to be tested before coming on site and when returning from a break, across every industry. BILLIONS upon BILLIONS of throw-away tests. As a small stockholder, my "hopium" is high. [Do your own due diligence.]
