Ancient Israel’s First Proof of Ritual Cannabis Use

Series Navigation: Part 6 of 16 in the Entheogenic History Series.

For decades, the idea that ancient Israelites may have used cannabis in religious ceremonies lingered more in the realm of linguistic speculation than archaeological fact. The “kaneh-bosem” hypothesis—the suggestion by scholar Sula Benet that the biblical term in Exodus referred to cannabis—fascinated historians and theologians, yet lacked physical evidence.

That all changed in 2020, when a groundbreaking study¹ on residue from two Iron Age altars at Tel Arad confirmed what no one had been able to prove before: cannabis was deliberately burned as part of ritual worship in ancient Judah.

This discovery didn’t just offer new data. It provided the first material proof of ritual cannabis use in the Ancient Near East. The Tel Arad altars became the smoking gun.

A Shrine Frozen in Time

Tel Arad, located in the Beer-sheba Valley of southern Israel, has long been one of the country’s most revealing archaeological sites. Excavations decades earlier uncovered layers of fortresses dated from the 9th to early 6th centuries BCE that guarded the southern (SOMN ) border of biblical Judah. Those digs also revealed something incredibly rare: a remarkably preserved Judahite shrine dated to around 750–715 BCE.

At the entrance to the shrine’s “holy of holies,” excavators found two limestone altars lying in place. Both had the remains of a hardened black organic residue.

At the time, analytical methods were limited, and earlier attempts to identify the material were inconclusive. But the altars remained carefully preserved, and eventually, modern science caught up. More than 50 years after their discovery, the samples were reanalyzed using advanced organic residue testing. The results were astonishing.

Cannabis on the Smaller Altar: A Deliberate Psychoactive Invocation

The smaller altar contained clear chemical signatures of cannabis. Even more telling was the discovery of animal dung mixed into the residue. This wasn’t incidental contamination. Dung was intentionally added as a slow-burning fuel source that could help the cannabis vaporize at a controlled temperature, allowing its psychoactive compounds to disperse.

This suggests purpose, planning, and ritual understanding.

The presence of cannabis was not symbolic or aromatic; it was functional. Ancient priests or practitioners were heating a psychoactive substance in a controlled environment inside the holiest part of the shrine. The goal would have been to induce altered states of ecstasy, heightened spiritual awareness, or some form of ritual trance—phenomena now explored through the lens of neurotheology.

This was the first time that cannabis had been identified in the Ancient Near East and serves as confirmation that psychoactive plant use was embedded within Judahite cultic practice. Cannabis wasn’t incidental. It was central to the experience.

This finding also shifts the “kaneh-bosem” debate. Previously, arguments relied on linguistic analysis, tracing how words for fragrant reeds could linguistically match terms for cannabis. Critics argued the theory lacked proof.

Tel Arad changed the equation completely. Whether or not “kaneh-bosem” meant cannabis, the material record now confirms that cannabis was used in Israelite religious settings. The theory moved from possibility to historical plausibility, and the conversation about cannabis in biblical ritual shifted forever.

Frankincense on the Larger Altar: A Window Into Ancient Trade and Theology

The larger altar contained an entirely different substance: frankincense. Chemical analysis revealed its resin was blended with animal fat, likely to help the incense evaporate steadily and release its aroma more effectively.

Frankincense is not native to Judah. It comes from Arabia, making its presence in an 8th-century BCE shrine significant. It provides the earliest clear evidence of frankincense in a cultic context in Judah, long before Assyrian oversight encouraged long-distance trade. Its use at Tel Arad suggests that Judah participated in the South Arabian incense trade earlier than previously documented.

More importantly, frankincense was the classic Temple aroma. Biblical texts describe it as part of the incense offerings in Jerusalem, symbolizing purity, sanctity, and divine connection. That Arad’s priesthood used it in their rituals shows how regional shrines mirrored, or perhaps influenced, the practices later centralized in Jerusalem.

Together, cannabis and frankincense on adjacent altars paint a vivid picture of complex, multi-layered ritual performance. One altar offered fragrance and sanctification, while the other delivered an intentional psychoactive experience.

A Ritual Blueprint: What the Tel Arad Shrine Tells Us About Ancient Worship

Until now, reconstructions of ancient Judahite ritual life have relied mostly on texts that were shaped by later editors, political reforms, and theological agendas. Tel Arad gives us something incredibly rare: a snapshot of practice untouched by later reinterpretation.

The fact that two altars sat side-by-side at the entrance to the holy of holies hints at coordinated ritual actions. The burning of frankincense likely created the sacred atmosphere expected by worshippers, while the burning of cannabis induced an altered state that could deepen spiritual experience.

This combination is not entirely unique cross-culturally. Many ancient societies used psychoactive substances during religious ceremonies to dissolve boundaries, heighten emotional intensity, or facilitate experiences interpreted as divine encounters. What makes the Tel Arad discovery so groundbreaking is that it anchors these ideas firmly within the history of Israelite religion, a tradition often thought of as strictly sober, aniconic, and text-governed.

The archaeology now says otherwise.

Why the Tel Arad Cannabis Discovery Matters

The Tel Arad altars challenge long-held assumptions about biblical religion. They reveal that early Judahite worship was far more diverse and experiential than later texts might suggest. They also show that psychoactive plants played a deliberate role in cultivating ecstatic states in at least some Israelite rituals; a revelation that widens our understanding of ancient spirituality.

This discovery also brings scientific clarity to an issue often dismissed due to stigma. For decades, the suggestion of cannabis in ancient Israel was met with skepticism or even derision. Now, we have hard evidence: the residue, the chemical markers, the ritual context, and the archaeological integrity of the site all align.

The cannabis on the smaller altar wasn’t accidental. It was intentional, functional, and sacred.

From Hypothesis to Proof: A New Chapter in Cannabis History

With Tel Arad, the narrative shifts. Cannabis is no longer merely a speculative ingredient in ancient anointing oils or incense formulas. Its presence is confirmed at a state-supported shrine from the 8th century BCE.

This is the first proven case of psychoactive cannabis use in the entire Ancient Near East, and it belongs to the religious world that shaped the Hebrew Bible.

The implications are profound. They invite scholars, theologians, and historians to reconsider long-held assumptions about ancient Israelite ritual practice. They also reopen linguistic debates, now strengthened by archaeological validation. And they affirm something that many researchers have long suspected: psychoactive plants have a deeper, older, and more widespread role in human spirituality than traditional narratives acknowledge.

In Tel Arad, the past finally speaks, in burnt resin, in lingering cannabinoids, and in the stones of a quiet shrine once filled with smoke.

In the next article, we move from the Old Testament to the New, exploring the controversial theory that Jesus performed healing miracles using cannabis-infused oil.
