Yes. You outed me. That's exactly the point I'm making. I'm claiming Adderall has no noticeable effects. I'm also claiming caffeine does help people stay awake and that pot doesn't give people the munchies. While we're at it, morphine doesn't help with pain. I am taking the hard-line position that all well tested drugs have no efficacy.
Seriously, I don't think people doubt mind enhancing drugs exist. We're skeptical of manufacturers and people who believe they've "researched" nootropics because they've read a lot of stuff on the internet written up by marketing guys, PR men, and researchers willing to do shoddy research for money.
