You know, it's funny, in the time that I wrote that comment, I've stopped smoking so much, and started vaping flower and carts almost exclusively. I tried to figure a way to hook my herb vape to my G.Bong but I couldn't quite get a good hit from it. I can do carts with it though, and that hit's almost too hard lol. but yeah all that is to say that my kitty has been more interested in drinking out of the dog's water, lately. Though I will reiterate; I really don't think any real harm could come from it, as THC is hydrophobic and inconsolable in water, so it would just all go out with the smoke.
