Alcohol is an intoxicant, and 100% alcohol kills all life...There is a big difference between herbal medicine, and drugs which cause some form of poisoning to make an affect.
Cannabis is a part of a cannabinoid system, it is the same system the plant uses in our neurochemistry.
Many psychedelics affect a small region of the brain the precursor to the pineal gland, which is basically our antenna to the Divine.
Once this opens in many they then can connect, some people are born knowing Yoga (connection); I believe I could teach it to a shamanic level, yet I do not perceive everyone is a natural clairvoyant, the psychedelics activate this part of the brain.
Cannabis regulates the neural firing, and is needed to stop overloading in people with epilepsy; yet as a food in our diet it is an essential food, like any vitamin.
Without the omega oils that cannabis contains, the brain will over-fire, not think laterally, overly compartmentalize, not be calm to meditate properly, not see the state of inner reflection from rushing ahead, etc.
There have been scientific studies on omega 3 alone, cannabis contains a full range of omega oils, and the full range of amino acids needed for human life.
Thus we need to stop seeing food/herbs as being drugs, and recognize pharmaceutical comes from the word for witchcraft (G5331 pharmakeia).
Revelation 22:2 In the middle of its street. On this side of the river and on that was the tree of life, bearing twelve kinds of fruits, yielding its fruit every month. The leaves of the tree were for the healing of the nations.
Cannabis can produce oil, rope, cloths, paper, fuel, food, healing, plastics, housing, etc.
It's roots thrive in 23 degrees earth, which means it can grow in nearly desert, and is a tree within a year; which means it literally can be used for saving this planet, and is the root of of the world's major religions, given to us by Sky Beings.
Like take into account currently there is tons of modern research into entheogens, and no real study of its interconnection with metaphysics - do we see the inevitable problem?
In my opinion.
