I don't drink the stuff. I am not worried about it being bad, but it just makes me hungry.
I believe the recent study they did to criminalize aspartame they injected it directly into the cell at very high concentrations. First, if you inject most substances, to include amino acids, directly into a cell it will die. Dumbasses. Second, the concentrations they injected the cell with would mean you would have to consume your bodyweight in aspartame every day to reach those levels of concentration.
