I actually agree with both sides here.
I have an overstanding that we are currently living in the babylon system, and I think it is no coincedence that these plants have been placed here for us by jah, because they give us profound, as shiva said earth shattering insight that completely change everything that you ever knew to be true. They are true tools to help a person transcend the system, in a ONE OFF insight.
There are many accounts of the traditional use of Peyote in soul revealing ceremonies. You seem to believe more in what Babylon tells us about the scientific facts. Would you trust babylon more than traditional ceremonies that utilize a PLANT?
If this insight is used for good, and never returned to, or very rarely, then this is very good.
However, I agree with Garveys Africa in the sense that if one becomes addicted to these plants, then this can cause harm. Keeping the body clean from the inside; free of the babylon food is the reliable route to consciousness.
I see these gifts (Peyote) more as something which should be used ONCE. Once the person has had this insight, they will never doubt the spirit again. I see them more as a tool to lift the person out of babylon state of mind, so that they can go on in the RIGHT direction.
It is the WRONG direction to continue to take the peyote all of the time. Once is enough.
All the best,
