I also agree and think that it played a detrimental role in my mental health. Now that I don’t smoke for more than a year I can feel “scars” that cannot be healed.That's sad to hear .looking back I was quite content I think which may have helped me to smoke often.i started full on when I was only 16 ,taking pipes in toilets during college then talking buckets at night with friends .
I suspect that played a big part on my mental health as I got older .I'm not sure if your brain is fully developed at 16 I suspect not.
I never seen grass till I was about 19 it just wasn't around
Maybe we’re wrong and the brain will heal itself. I went full on from 14 as well.
