I just realized the same thing about connecting tobacco use to spiritism in the 73 article as well...
32 Note that the first ones whom Jehovah mentions as the targets of his speedy witness regarding their wrongdoing are the “sorcerers.” The Greek Septuagint Version, as translated by Alexandrian Jews before Christ, rendered “sorcerers” by the Greek word phar?ma?kous′. This is the same word used in Revelation 21:8, where some translators render it as “sorcerers,” but the New World Translation renders it as “those practicing spiritism.” The ancient sorcerers indeed practiced spiritism. The Greek word applied to them literally means “druggers,” not “druggists” such as “pharmacists.” The ancient sorcerers were the drug pushers of their day.
33 The pre-Christian Greek Septuagint Version uses the related Greek word phar′ma?kon (meaning literally “drug,” but translated as “sorcery”) at least five times. Idolatrous Queen Jezebel of ancient Israel practiced such phar′ma?kon (in the plural number) or “sorcery.” (2 Ki. 9:22, LXX) She was executed by King Jehu acting as Jehovah’s executioner. Those who patronized the professional “sorcerers” or practicers of spiritism also participated in spiritistic practices and were condemned.
34 It is little wonder, then, that, in these days of widespread addiction to drugs and the growing use of tobacco, those indulging in such things should come under judicial observation. Jehovah God, the Supreme Judge, is at his spiritual temple and is specially scrutinizing those who profess to worship him in that holy place. He has promised to be a speedy witness against the sorcerers or the practicers of spiritism, which from ancient times onward had a connection with habit-forming, enslaving drugs.
35 Do we want to have Jehovah God be a speedy witness against us as addicts to drugs or other habit-forming injurious weeds, things that expose us to the influence of the spirit demons? Jehovah’s judgment against such addicts during the oncoming “great tribulation” will mean their destruction. (Rev. 21:8) Most assuredly, Jehovah God does not want such addicts among the congregation of his Christian witnesses now in this “conclusion of the system of things.” Of the promised “New Jerusalem,” Revelation 22:15 says: “Outside are the dogs and those who practice spiritism [the druggers, Kingdom Interlinear translation] and the fornicators and the murderers and the idolaters and everyone liking and carrying on a lie.”
