IF people do not specifically want this ingredient, at least they may now be aware that it can cause an increased heart rate. This can be dangerous for someone with unrecognized atrial fibrillation. I am not speaking about the requirement for signature, etc., just the publication that it is not a benign ingredient.
Not benign, but damn effective. I can't think of a substitute with equivalent efficacy.
And, when turned into Meth we are no longer discussing dancing merry makers, but something more like crazy people with their teeth falling out.
