The current lack of adequate data or convincing analysis is not a problem from the perspective of DEA or other enforcement agencies . The lack of a unified set of file numbers for the federal criminal-justice agencies , or a set of links from one file system to the next ( what is called an " Offender-Based Tracking system , " or OBTS ) makes it nearly impossible to trace a sample of DEA defendants through prosecution and incarceration . Under that statute the Administrator of DEA can bring a drug under Schedule I for up to one year , with a six month extension where justified , and on emergency basis , while the normal control mechanism is in progress .
