I believe maturity to be able to handle moral dilemmas and or life rationally. To be able to postulate how to solve your problem effectively. To be able to give advice and to listen. The ability to look back, self consciously, and see things in a new light then we could at that particular age. Smoking cannabis, allows us to maturity, it exposes the truth and it exposes the lies. Those who help uncover the bias and unjusice of this, are cool.
