At a time when the eating of a poppyseed roll can put a measurable quantity of opiates in your system, the International Olympic Committee has to decide the level at which drugs are "performance-enhancing" at the time of the performance as well as the acceptable levels of others, like steroids, that might be used to attain a superhuman performance. ROBERT F. DRAKE Bronx, Feb. 13, 1998 The writer is an assistant professor of chemistry, Bronx Community College. - ----- To the Editor: The decision to let Ross Rebagliati keep his gold medal despite testing positive for marijuana was the right call (Sports pages, Feb. 13). Had the arbitration panel ruled against Mr. Rebagliati and upheld the International Olympic Committee, a message would have gone out to youngsters that marijuana is considered a performance-enhancing substance by the Olympics. In the absence of any proof that its use enhances performance, athletes need not be tested for it in the first place. RICHARD M. EVANS Northampton, Mass., Feb. 13, 1998
