I called it very dangerous because one without knowledge of the other ingredients "Guarifisen sp*, etc" can end up taking a dose that isn't just dxm, such as coriciden cold and cough (triple c's, skittles). And if you don't work your way up in the plateaus, to a first timer, a third plateau trip can be absolutely terrifying. My first trip was a third plateua, and it was life altering.
