Here's an article from a pro-Cannabis (and pro-Crowley) website, which features the use of cannabis by Crowley. I offer the last two paragraphs from the article. Crowley also wrote a book called 'The Psychology of Hashish':

Aleister Crowley and the Devil's Weed | Cannabis Culture


"Utilizing cannabis, mescaline and a variety of other substances, Crowley would create and perform mythologically imbued occult rituals, which were directed at bringing the devotees into closer contact with higher states of consciousness. He had hopes of perfecting a method which would make the mystic frame of mind available to humanity at large. Far from seeing his work as something new and novel, Crowley rightfully saw such drug induced ritualistic initiation as being part of the ancient mystery schools which had been largely suppressed by the Catholic Church at the commencement of the dark ages.

"Considering the strong role it played in his magical techniques, it is curious to note that after Crowley wrote The Psychology of Hashish, there are only a few scattered direct references to cannabis in his writings. But with a little cross-referencing, it can be shown that cannabis use is at the core of this famed magician's most celebrated occult texts, a fact that many Crowley enthusiasts are unaware."

Of course the devil knows how to misuse God's gifts.

Bringing forth grass for cattle, and herb for the service of men. That thou mayst bring bread out of the earth:" [Psalms 103:14]

And God said: Behold I have given you every herb bearing seed upon the earth, and all trees that have in themselves seed of their own kind, to be your meat:
Genesis 1:29

True. What is it about cannabis, specifically, that would cause it to be misused? Why would it be misused in an occult ritual, do you think?

You will have to ask the devil, who uses many of God's creations inappropriately.

It isn't necessary to ask the devil. The answer is obvious. Though potheads and their supporters will pretend otherwise.

They also misuse/abuse Catholic things in their rituals as well as their procreative powers.

Yes, but it's not the same thing as using cannabis for occult ritual. For occult ritual, cannabis is used specifically for its psychoactive effect. Crowley believed that it could cause his believers to obtain altered states of consciousness. Whether cannabis really has that ability, I've no idea, but he certainly thought so.

If you want to believe that we should not post the negative things associated with pot, that's your choice. But as long as I'm allowed to do so, I'll speak out about the negative aspects. Or as long as certain posters are on a crusade to show that pot can only be used for good, with little side effects.

The satan-worshipping American indians used alcohol as part of their rituals, as do many witches.  I guess all alcohol should be banned, including the priest at Mass. 

  You have the logic aptitude of a newt.  Please stop.

To put a fine point on the illogic: Satanic Black Masses exist, so ban all Masses.

Good grief.

Protestants use Scripture, therefore, all Catholics who use Scripture are Protestants.
