One day we my wife's mom walked in the house and found her little pup with a bag of chronic just haging from his mouth. Funny part is, the bag was inside a backpack and rolled up in a towel on top of that. He REALLY wanted at it.

We where young at the time and we just said we knew nothing about it. I took a pic at the time and the image of this dog with a ziplock hanging from his mouth was one of the funniest things I have ever seen.

To answer the question of the topic... I do not believe in smoking out your pests. They have no choice.

One other thing... Giving a cat a hit of acid is one of the funniest things you will ever see in your life!! (no it wasn't me but I was there).
