Efimova is scheduled to compete at the World Championships this year; will her victories forever be tainted? She has twice been suspended for positive drug tests, both times claiming innocence, and both times having the suspension
In 2013, Efimova tested positive for the drug 7-keto-DHEA in an out of competition drug test. (See https://examine.com/supplements/7-keto-dhea/) (http://www.webmd.com/vitamins-supplements/ingredientmono-835-7-keto-dhea.aspx?activeingredientid=835 ). At the time Efimova tested positive she had only been living in the USA for a short time and knew very little English. Efimova stated she did not understand the salesperson. Efimova was banned for 16 months. Efimova was stripped of four short course world records. In 2015, after serving the suspension, Efimova returned to competitive swimming and won a Gold Medal in the 100M Breast at the World Championships.
As Efimova trained and prepared for the 2016 Rio Olympics, Efimova was suspended again for the drug meldonium. Meldonium is a drug produced in Latvia under the commercial name Mildronate. See the following website for more information: https://www.outsideonline.com/2067801/what-meldonium/mildronate (after track athletes were suspended) (http://www.medicalnewstoday.com/articles/309165.php).
However, Efimova had her suspension lifted and received clearance to compete, but was then suspended again having lost her appeal just before the Rio Olympics. Ultimately a decision was made by Swimming’s Governing Body on the day of Opening Ceremonies that Efimova was cleared to compete, less than two days before the 100M Breast preliminaries.

Having been cleared just days earlier to swim, Efimova finished second in the 100M Breaststroke to US Swimmer, Lilly King. She then took another silver in the 200M Breaststroke.
Efimova is scheduled to compete at the World Championships in Budapest later this summer.
