No, young brains were not smoking the same strength as when we were young. It is 10 times stronger and they are proving it has a lasting effect on undeveloped brains.
You never smoked 1980’s skunk weed, did you?
And yeah, I wouldn’t want kids smoking it either, but they are either going to or not going to regardless of anything you do or do not do.
Everyone makes their own choices in life, and you can’t save people from bad ones.
Let’s not forget that 25 year olds still have “undeveloped” brains. I had thought that brain development continues until age 25, but I have recently heard scientists at conferences say that the brain does not mature until age 30. Meaning that marijuana use among the young is a bigger problem than we thought. It is not likely that a 30 year old who has stayed clean his whole life is going to take up marijuana use, and the younger people who are more inclined to experiment are at the highest risk for brain damage.
