Arguments For/Against Spiritual Uses of Cannabis in Christianity?

As I am aware most Christians regard the physical and spiritual effects of Cannabis as the same as use of alcohol for intoxication, and that its use is not permitted by their doctrines. Contrarily, some Christian denominations such as the Rastafari and Ethiopian Zion Coptic Church not only allow its use but strongly suggest its use for meditation and communication with God. Now, I realize that Cannabis use is a controversial topic for many devout Christians and many will not give it a second thought as to whether it has any place in worship. Through some research I have landed upon the following article regarding its use in the time of Jesus: Jesus 'healed using cannabis' . Cannabis is often referenced in the Bible as Calamus (hebrew 'קנה-בשם' or "kaneh bosm"), as in the following scripture: >"Take thou also unto thee the chief spices, of flowing myrrh five hundred shekels, and of sweet cinnamon half so much, even two hundred and fifty, and of sweet **calamus** two hundred and fifty" (Exodus 30:23 ). > >"Vedan and Javan traded with yarn for thy wares; massive iron, cassia, and **calamus**, were among thy merchandise" (Ezekiel 27:19 ). > >"Spikenard and saffron, **calamus** and cinnamon, with all trees of frankincense; myrrh and aloes, with all the chief spices" (Song of Songs 4:14 ). There is no debate that Cannabis was used in the time of the Hebrews and throughout the time of Jesus Christ. I am neither for nor against the use of Cannabis, I only wish to see arguments for/against its use as an aid in spiritual connection with God and developing a deeper understanding of his Word. Any insights on this?
