What they found was a substance called N,alpha-diethylphenylethylamine (N,a-DEPEA), which the researchers called structurally similar to methamphetamine.

What does 'structurally similar' mean in a chemical sense? Isn't there a profound difference between 2 chemicals that have even a 1-molecule difference? If they had said 'similar in effect' or something like that, I would be more concerned.
. . . just like Ultimate Orange in the 80's, Ripped Fuel in the 90's, Jack3d, and Craze.
The supplement industry will just keep tweeking (no pun) the chemical structure to create a new amphetamine to stay ahead of the FDA ban hammer. Can't stop the need for speed, the market demands it.
Personally my ticker can't take it anymore, a strong cup of black coffee and I'm good to go.
