Do some more research on it.

You have the main part right, cannabis needs to be cooked into something high in oil and fat, and a sausuage would be just that.

I would be concerned about a few things though: The first one being that if you are looking to get high from doing this, keep in mind that cannabis has a vaporizing temp. of 220degC. From my BBQing and cooking knowledge, a sausage has to cooked at a MUCH higher temp than that to cook.

Another thing I would concerned about is the amount of grease and fat they lose after they get cooked. They lose a lot that fat, not all of it, but a nice chunk, so I would worried the THC goodness would go into the grease pan, and down the drain or garbage.

Keep those in mind. Mostly the vaping one. Once the cannabis reaches beyond 220degC, it is no longer good for getting. That is about 450degF, and I'm sure meat cooks at a way high temp. than that.

It would taste good though.
