Today, cannabis continues to be a subject of research and discussion in both medical and recreational contexts. Studies into its effects and applications are ongoing, while the legal status of THC and cannabis varies worldwide, with some countries choosing to decriminalize or legalize their use.

Evolution of Cannabis Cultivation and Medicinal Use

Over the centuries, cannabis cultivation and its medicinal use have spread from Central Asia to ancient China, Egypt, and Greece. The cannabis plant, known scientifically as Cannabis sativa, has been prized for its versatile properties and has played a significant role in various cultures throughout history.

In ancient China, cannabis was cultivated for its fibres, which were used to make textiles and ropes. The medicinal properties of cannabis were also recognized, and it was used in traditional Chinese medicine to treat various ailments, including pain and inflammation.

"The Chinese Emperor Fu Hsi (ca. 2900 BC), whom the Chinese credit with bringing civilisation to China, seems to have made reference to Ma, the Chinese word for Cannabis, noting that Cannabis was very popular medicine that possessed both yin and yang." - Hemp: American History Revisited: The Plant with a Divided History, 2003.

Ancient Egyptians utilized cannabis for both medicinal and religious purposes. The plant was considered sacred and was associated with the goddess Seshat. Cannabis was used in the preparation of ointments and oils, believed to have healing properties. It was also used in religious rituals and ceremonies. 

Cannabis pollen is found on the mummy of Ramesses II, who died in 1213 BC. Prescriptions for cannabis in Ancient Egypt include treatment for the eyes (glaucoma), inflammation, and cooling the uterus, as well as administering enemas.

Bhang, a cannabis drink generally mixed with milk, is used as an anaesthetic and anti-phlegmatic in India from 1000 BC. Cannabis began to be used in India to treat a wide variety of human maladies.

In ancient Greece, cannabis was regarded for its medicinal properties as early as 200 BC. The physician Dioscorides documented its uses in his influential work De Materia Medica, noting its applications for easing pain, reducing inflammation, and serving as a sedative. Cannabis was also recognized for its psychoactive qualities and, in some contexts, was used recreationally.

After the 1500s, with the spread of Islam to India, Muslim physicians applied Persian medical theories to their use of cannabis. Their practices often emphasized its later effects rather than the immediate ones, employing it, for example, to reduce sexuality rather than to stimulate it.

Jesus Allegedly Uses Anointing Oil Made With Cannabis

Chris Bennett wrote the following in High Times Magazine in February 2003:

"In the Bible’s New Testament, Jesus... anointed [his disciples] with [a] potent entheogenic [psychoactive substance] oil, sending out the 12 apostles to do the same [around the year 30 AD]...

Likewise, after Jesus' passing, James suggests that anyone of the Christian community who was sick should call to the elders to anoint him with oil in the name of Jesus."

"So, did Jesus use cannabis? I think so. The word Christ does mean 'the anointed one' and Bennett contends that Christ was anointed with chrism, a cannabis-based oil, that caused his spiritual visions. The ancient recipe for this oil, recorded in Exodus, included over 9lb of flowering cannabis tops (known as kaneh-bosem in Hebrew), extracted into a hin (about 11? pints) of olive oil, with a variety of other herbs and spices. The mixture was used in anointing and fumigations that, significantly, allowed the priests and prophets to see and speak with Yahweh.

Residues of cannabis, moreover, have been detected in vessels from Judea and Egypt in a context indicating its medicinal, as well as visionary, use. Jesus is described by the apostle Mark as casting out demons and healing by the use of this holy chrism. Earlier, from the time of Moses until the later prophet Samuel, holy anointing oil was used by the shamanic Levite priesthood to receive the 'revelations of the Lord'. The chosen ones were drenched in this potent cannabis oil."

The cultivation and medicinal use of cannabis continued to evolve over time, with different cultures adopting their own practices and beliefs surrounding the plant. The spread of cannabis cultivation and its medicinal applications laid the foundation for its use in modern medicine and the ongoing research into its potential benefits.
