Mr. President. an article published in the Miami Herald of August 7. 1970. calls public attention to the proposal of a Broward County. Fla..doctor to use the controversial drug Ritalin on migrant children. In view of the unknown qualities of this drug. it is particularly disturbing to learn that it is the children of migrant and seasonal farmworkers who are the recommended guinea pigs upon whom the drug will be used. The full implications of the needs and use of the drug are set forth in the Florida newspaper article. and in a feature story and editorial in the Washington Post. which I would also like to bring to the attention of the Senate. Especially disturbing is that certain preconditions for the use of this drug cannot possibly be met when experimenting with the migrant farmworker population. Proper administration to children requires careful and accurate diagnosis of possible behavioral disorders. In view of the desperate lack of funds for fundamental preventive health care for farmworkers. it is difficult to imagine where sufficient funds for adequate. thorough or correct diagnosis will come. and even if funds are available. serious question of health care priorities is voiced. Additionally. the drugs should be administered under careful control and in the presence and guidance of a physician. Yet. by definition. the migrant is mobile. and often lives in remote locations. thus eliminating the reasonable possibility of sustained continuous medical treatment. As chairman of the Subcommittee on Migratory Labor I have today called upon the various Federal Government units that administer migrant programs. and whose funds are proposed to be used. to respond to the following inquiries. Are federally funded programs involved in the use of behavior modification drugs such a Ritalin. and if so. is the use of these drugs fully approved by your unit? What assurance do you have that these drugs are necessary for migrant children? What guarantees do you have that these drugs will not do any physical or mental harm to any of these children? And finally. in view of the mobility. impoverishment and history of exploitation of so many migrant and seasonal farmworkers. and the possibility that. parents have only limited opportunities or channels to protest the use of these drugs. what protections for the individual rights of the parents and children involved has your unit recommended? Let me emphasize that I am not interested in blindly standing in the way of medical progress. But let us not use the kids of the Nations most powerless persons as guinea pigs in the name of progress.
