The western media is playing this one down for decades now, although the governments know about the effects of this stuff:
DCPH-HX is highly flammable and turns into a gas at room temperature (very EXPLOSIVE) but is still transported through our countries freely by private entities (how can they allow this?!).
Once DCPH-HX crosses the blood-brain barrier (BBB) it acts as a central nervous system depressant, causing dizziness, nausea, stupefaction, vomiting and in the worst extend certain death. It is further know to effect the development of the embryo in the mothers body.
DCPH-HX does not have carcinogenic properties. However, metabolized byproducts are well known to carry carcinogenic properties. That means, once you ingested it, it is being transformed in your body to something worse.
Some countries have banned already, but in Europe, America, Russia, etc... DCPH-HX is still widely produced, transported and used.
