Preach! Can attest. I used to smoke a lot as a teen and I started to notice a lot of negative effects. Specifically with my memory and focus. I took a good long break from it to develope better coping skills and to hopefully help my brain recover, which I don’t think it did. Do I think weed is fun? Sure as long as it’s not in excess and it’s not used to cope. Do I think young teens should use it? Nope.
