In reply to the discussion: Casual marijuana use linked to brain changes [View all]hedgehog
(36,286 posts)therefore there couldn't be any brain changes involved! The questions to be resolved are what kind of brain damage, how permanent, what's the dose relationship and what's the effect of age. I'm especially leary of the possible connection to schizophrenia.It's possible that this is a matter of activating a pre-existing tendency and/or activating it earlier than otherwise. This is an area that needs careful study.
That said - alcohol is clearly harmful to developing brains. (BTW - we know about fetal alcohol syndrome - fetal MJ syndrome?)
That said - drinking gasoline is harmful to the brain, but there is no law against it. We need to find out any and all consequences involved with smoking marijuana, and be honest about the results. After that, it's better to allow individuals the freedom to harm themselves than to distort our society with laws against something so many people use.
