In November, I published a blog post in which I said that marijuana should not be used to treat ADHD. I have not switched my opinion on that. However, while researching for the second edition of ADHD Talks, I realized that it was not as black and white as I once thought. In fact, it is quite gray (Do you like how this blog post’s featured image is a grayscale version of my previous blog post? That was intentional because of how this issue isn’t black and white; it’s gray. I thought it was clever). As of right now, I do not know if marijuana is a safe effective treatment for ADHD, but it could be.
