I smoked all through middle and highschool. My brain didnt perpetually stay 15 years old, now theat im 33 acording to you my mind shouldnt be any more developed than it was when i started smoking at age 15......if thats the case i shouldnt be able to hold down a job, take care of my kids, or do any of the normal adult things that i would do on the daily. Your logic is.....well.....not logical to be honest.
