  Substance Attributes


  • Toxic to specific organs

    Can damage liver, kidney, lungs, heart or gut. Ironically liver, kidneys and gut are the main detoxifications systems.

  • Soluble in Water

    This substance easily dissolves in water. As such it can be easily transported via waterways. Not really a nastiness attribute, but this feature helps rapidly spread other nastiness attributes this substance may have.

  • Has known Side Effects

    This is often the result of long or short term medication use. The same medication can have a range of side effects ranging from none at all to totally debilitating symptoms within different individuals. Reasons for this include individual genetics, individual detoxification capacity, nutrition status, duration of use and total number of medications being taken.


    It becomes very difficult to establish clear causes of symptoms when multiple medications are being taken at once.
