Quite a while back, I downloaded some program for binaural beats and several different tracks that were supposed to have varied effects. I got out my nice headphones, put on the “marijuana” track and listened for half-an-hour. At the time, I thought I might have felt a little something, maybe light-headed. Looking back now, I don’t remember feeling much of anything.
I think you can toss this one into the “internet myths” pile.
