Hah! Back in 2010 when I was a teenager and before I had tried drugs of any kind I became fascinated with something called I-doser, which are "binaural beats" marketed as audio drugs.

They basically offered mp3 files which would emit sound waves which would allegedly mimic certain drugs.

After reading success reports on forums, I tried a few and from memory it did slightly put me into a meditative state but nothing more.
