At its May 11 meeting WADA’s Executive Committee decided to
increase the threshold level for cannabis following consideration of the
many submissions received from stakeholders during the Code review
Accordingly, the Technical Document on Decision Limits for the Confirmatory Quantification of Threshold Substances (TD2013DL) has been revised to reflect the applicable modifications affecting compliance decisions for Carboxy-THC.
Version 2.0 of the TD2013DL is effective as of May 11, 2013, and can be found on WADA’s Web site.
All samples received by laboratories post-May 11 will be subject to the new threshold level.
As a matter of fairness and to provide consistency, WADA advises not
to pursue cases currently in the results management phase where the
reported concentration is less than the new threshold (150 ng/mL).
Also, for any analyses conducted from May 11 onwards, laboratories
are requested not to report any THC case result below the acceptable
threshold, regardless of the sample receipt date.
