The reproduced 1956 statutory edition records 1 January 1936 for the Poisons, Opium and Dangerous Drugs Ordinance; the NDDCB chronology confirms operation in 1936 after the 1935 amendment. This documents the later operational milestone without backdating every provision of the subsequently amended statutory edition to that day.[1][2]
