The investigation lead to the arrest of Italian doctor Enrico Lazzeri and the discovery of the use of ozone therapy, or ozonated autohemotherapy as it also known. Some countries do allow limited use of ozone therapy but the results have never been confirmed in medical trials and carry a risk of embolism and could damage red blood cell's membranes.

anyone know more about this?
the risk sound similar to EPO - so if the risk level is the same, it probably wont stop riders from using it.
