captain hanks:

Calamus is a common marsh plant. In ezekial God becomes angry when they didn't bring him any "exotic calamus from distant lands." Cannabis was grown distant from the tabernacle (most likely) during this time. Saying that calamus was the correct translation of kaneh-bosm when translating from Hebrew to Greek (the words differ by an accent mark, easy mistake) would have rendered Gods' complaint ridiculous. "Though has not broughten me any common marsh plant from distant lands." (After this episode the tents were filled with smoke).
Here is the passage from Ezekiel. This is the only mention of calamus in ezekiel. It is part of a prophecy directed towards Tyre. There is no mention of God getting angry because they couldn't find calamus. There is no proof to support whether calamus was grown near the tabernacle. There is no mention of the tent being filled with smoke. (let alone smoke of marijauna). There was incense used by the preists, but there is no proof whatsoever that it was marijuana or that it even hints toward it.)

ezekiel 27

17Judah, and the land of Israel, they were thy merchants: they traded in thy market wheat of Minnith, and Pannag, and honey, and oil, and balm.

18Damascus was thy merchant in the multitude of the wares of thy making, for the multitude of all riches; in the wine of Helbon, and white wool.

19Dan also and Javan going to and fro occupied in thy fairs: bright iron, cassia, and calamus, were in thy market.
The micture they used with calamus was not for anything other than anointing the preists and items in the temple. That's it. If anyone else used it, they would be cut off from Israel as I pointed out before.

Also remember that the same word used for calamus is used several times as "reed" or "water plant", several times. cannabis is not a water plant, it's not a reed.
