Kids are told to stay away because THC, like most drugs, impacts brain development 😅
Once you’re 25 your brain is generally considered fully developed. The closer you get to that point the less of an issue it is, but kids shouldn’t be smoking weed all the time, it can impair your brain’s development.
Edit: there are corrections below regarding the age 25 as a brain development breakpoint
Huh, interesting. I thought it was with respect to the development of the frontol lobe and your ability to evaluate risk vs reward, I must have sort of mixed “facts” I learned at some point
Thanks for correcting me! ☺️
Edit: this seems like a good source if someone is interested to know more, scishow is very well researched and really good at communicating that research
