James Gist (2004-08) may be facing a FIBA ban after testing positive (translation) for Carboxy-THC (that's the chemical marijuana leaves behind in the body) last month during a routine post-game drug test on June 1st in Serbia.
Two samples are always taken, and Gist's sample A came back positive with low levels of the drug. So, if my understanding of poorly translated Turkish news and my memory of FIBA procedures is correct, sample B will now be tested by a different lab. If sample B comes back positive as well, then the ban could be anywhere from three months to two years.
Gist had just signed a new deal with reigning Turkish champion Fenerbahce Ulker last week. The team has said they will wait for the investigation to finish before management decides whether to keep Gist or not.
