Phencyclidine health effect

After completion of Volume 1, three new panels were established to Identify and assess evidence on the possible long-term health effects or delayed sequelae of the three chemical classes tested. This was done over a period of a year, during which each panel met three times. Pertinent material was examined to evaluate the possibility that experimental exposure of soldiers may have resulted in untoward health effects. The three panels were separately concerned with four cholinesterase reactivator chemicals (oximes) two types of psychochemicals (phencyclidine and dlmethylheptylpyran and congeners), administered In pure form, as opposed to street drugs and mustard gas and several lacrlmatory and respiratory irritants (such as CN, CS, CR, and CA). 

The Committee found the evidence on the long-term health effects of the tested psychochemicals to be sparse. The target organs that may be involved in prolonged or delayed effects of phencyclidine are the brain and cardiovascular system. Target mental or cardiovascular effects did not take place within a week of exposure to the drug. No case reports have identified long-term effects or mental or cardiovascular effects soon after first exposure.
