I will add my own experience to the mix.My oldest one is about done with high school and moving on to further education.Me and my mate are open about our mj use and proud.We both are self employed and in a position of this title not affection our core and buisness foundations.
My father ruled out that he shall be the one to smoke us boys royally out at age 17 as he rather us not seek the same else where on the streets and abroad.Moderator of sorts. We were allowed to burn down in the old man's greenhouse out back.One day i see my kid come through the door after school with those eyes only another pot head knows.
So i gave them the same oldman speech.Also my own take on when to partake and also times and periods of life when not to use and not be high.
My kid experimented a few months at home.Decided it was fun but best to have times clean for study.So my kid did not become a stoner on the daily and is headed to being on top in the game of their choice roadmap to success.
I will admit there are people who just should not use mj.
And we also have an endless list of successful people who only operate at 100% under the influence.
