Maria Sharapova is proclaiming her use of meldonium to be an accident. While taking full responsibility for the test, Sharapova also stated that she had been ingesting meldonium for her health since 2006.
"I did fail the test and take full responsibility for it," stated Sharapova. Given meldonium by a family doctor, Maria Sharapova claims she knew this substance only as "mildronate." Sharapova's former tennis coach Nick Bollettieri mentioned that her mistake was very honest, and went on to say,
"She said she took these for many, many years and then didn't read the memorandum that came out. I don't think that Maria Sharapova would continue doing something, especially being in the limelight, if there was something she knew about."

Expert doctors were also jumping on the anti-Sharapova bandwagon, chiming in that a healthy athlete would in no way need to take the banned substance meldonium.
In her detailed statement regarding the failed drug test, Maria Sharapova went on to say,
"I received a letter from the ITF that I failed a drugs test at the Australian Open. I take full responsibility for it. For the past ten years I have been given a medicine called mildronate by my family doctor and a few days ago after I received the ITF letter I found out that it also has another name of meldonium which I did not know. It is very important for you to understand that for ten years this medicine was not on WADA's banned list and I had legally been taking the medicine for the past ten years. But on January 1st  the rules had changed and meldonium became a prohibited substance which I had not known. I was given this medicine by my doctor for several health issues that I was having in 2006."According to Forbes, Maria Sharapova has been the highest earning female tennis player each of the last 11 years. She faces a stiff penalty, as much as a four year ban from Tennis. While some experts say a ban of this duration is unlikely to occur, there is a strong possibility that Sharapova may incur a one year penalty.
WADA president Craig Cheedie informed the Associated Press that an athlete testing positive for meldonium was likely to receive a one year ban from competition.
