Is apparently cannabis not calamus, which is actually a reed.

23 Take thou also unto thee principal spices, of pure myrrh five hundred shekels, and of sweet cinnamon half so much, even two hundred and fifty shekels, and of sweet calamus two hundred and fifty shekels,
-Exodus 30:23

Marijuana in the Holy Oil?
The original Hebrew for calamus, is Kaneh-bosem or Qaneh (Kaw-naw) Bosem. Some translations have this as “fragrant cane” or “aromatic cane.” Some researchers have argued that this is actually Sweet Cane or Sugar Cane, although the term sweet does not occur in the original manuscripts.

In the Hebrew terms such as Elohim (Pronounced El- Oh- Heem ) is rendered plural. So in the Hebrew Kaneh-bosem is also plural. The singular then is rendered Kaneh-bos.

Kaneh-Bos sounds remarkably close to the modern day word Cannabis. Could it be that cannabis was the plant given by God to be used in the Holy Anointing Oil?

Cannabis and Christ: Jesus Used Marijuana
After the fall of the Jewish kingdoms, and the bloody purges following the forged discovery of the Book of theLaw (1 Kings 23), the cannabis holy oil was prohibited as associated with pagan worship. Yet it seems that certain sects retained the topical entheogen, and continued to practice the older religion, silently awaiting the return of a Messiah-king in the line of David.

The ministry of Jesus marked the return of the Jewish Messiah-kings, and thus the re-emergence of the holy oil. Jesus was called the Christ because he violated the Old Testament taboo on the cannabis oil and distributed it freely for initiation rites and to heal the sick and wounded.
