Hey, guys I'm 16 and I just started smoking weed recently. I heard that the brain is not fully developed until the age of 25, and at the age of teen years, vital parts of the brain are being developed and if you smoke weed, you interfere with brain development. I know this is true, but how bad is it? I am very good in school, all A'S and some B'S, and I want to go to a top level 4 year college/university. When people say it interferes with brain development, what are some possible risks/outcomes of smoking in your teen years? I'm guessing: -Permanent short term memory when you get older -Inability to concentrate efficiently as compared to those who did not smoke weed as teens - Solving and Logic is Impaired/Weak compared to non-smokers as teens Should I quit, and start back up when I am in my 20's?
