Waiting for Amber Trichomes

I have been waiting patiently for more amber Trichomes to develop. Most are cloudy right now but I want to let this plant go until I get like 50% of each. It makes me nervous to hear "degradation of THC". So I guess that the CBN is what gives you the narcotic and couch lock high? I am looking for more of a couch lock, therefore, I will continue waiting. Or should I not?
