Oh this is not true. The plant does not eat itself during a drought. Our genetic composition is nothing of that of a plant, especially of the cannabis variety. Our bodily responses to stressors are not received in the same way as stressors are to plants.
In fact, the cannabis plant is able to morph its genetic code in something called phenotypic plasticity. In times of stress, genes and proteins are triggered which allow the plant to develop and grow differently in order to preserve itself. While doing this, certain enzymes are exasperated by the process allowing for the increase in all of the noteworthy items listed above.
A cannabis plant does not starve itself during a drought, it does not eat away at what it has left. It synthesizes and it goes through a morphology. I believe that is the common misconception with droughting in the masses, Moon.
You can't compare us to a plant...apples and oranges. I too was an athlete but our cannabis is more of the XMen variety than human as far as their ability to use their GNR system and adapt to stressors
