She had probably taken drugs before. Have you looked the ingredients of any sports supplement? For the most part they are drugs. She took a supplement that included that drug. She had used it in training according to her boyfriend. In the same way that most marathon runners experiment with their nutrition on their LSRs. She done nothing radically different than anyone else on the start line that day. She had planned on it to help her energy levels in the later stages of the race. In the exact same way you might any other sports drink supplement or energy gel.
Even at that the supplement she used is only banned due to one ingredient in it, which is due to possible side affects. I think many here could rattle off issues they've had with drinks and gels on long runs. I know I can for one.
The marathon is a big deal. It needs respect. Many of us forget that as we have done so many, but going on the report her heart issue was never reported to her GP. She chose to run 26.2 miles with that condition without consulting her GP, pushing for a faster time meaning working the heart harder in training and in the race.
There is no scientific proof this substance was in any way connected to her tragic death. The headlines are nothing but sensationalist gibberish to attract clicks and newspaper sales. If she did anything wrong it was a folly of youth and ignoring the heart issue.
