THC can degrade to other cannabinoids, such as cannabidiol or cannabinol, which can make one feel sleepy and disoriented.
Don't be confused when it says "degrade" what they mean is when you are growing, then lets say it starts out as cannabidiol, then goes to THC, then cannabinol. Naturally you wan't THC cause thats the best, but the other two DO produce effects.
