And it’s exactly the same case at the other end of the spectrum as well. If you are looking to be precise, heating THC in excess will pretty much destroy it completely. When making cannabis oil or butter, it is necessary to gently heat/fry the cannabis to get all of the good stuff out of it. If you scorch it or burn it however, it’s game over. It is always better to err on the side of caution and bring a thermometer into the kitchen if you believe it will be helpful.
