It depends. What they're referring to are drugs such as those for ADD and ADHD. I don't think those make you smarter. I think they make it so you conform better to societal standards, so you can more easily sit in a classroom. One might gain more knowledge from this, which makes them informed. I don't think their IQ goes up though.

The other key word in that picture is "may." There is no guarantee the drug would make you smarter. There are always side effects, so it would have to be a pretty damn amazing potential benefit for me to overlook those. Generally, I stay away from drugs which are meant to effect the mind, because the brain isn't fully understood yet.

However, if it were going to have a Flowers for Algernon type of effect - even if there was a known risk of death at some point - I would still be tempted to take it. I very much enjoy my intellectual pursuits and I think this world needs far more intellectualism. These days we revel in ignorance. The things I could do and think and understand before I died would make the potential loss worthwhile to me.
