No, we have never given our guys Marijuana, but I bought a new product from Global Pets Food where I buy their food. It's called True Love Hemp for Health Daily Chews. It's made by trueleaf, and is a Natural Antioxidant Support and Omega Fatty Acids. It has antioxidants Green Tea, Pomegranite, and Blueberry, DHA from whole cell algae to support cognitive health, and Hemp to support the body's normal response to inflammation. They are a soft chew that I break up into their kibble everyday.
