Israel's role in cannabis research
Israel's connection to medical cannabis research is foundational rather than recent. In the 1960s, Professor Raphael Mechoulam at the Hebrew University of Jerusalem first isolated and synthesized tetrahydrocannabinol (THC) — the primary psychoactive compound in cannabis — and later cannabidiol (CBD). This work established the biochemical basis for understanding how cannabis compounds interact with the human body.
Israel legalized medical cannabis in 2007, one of the earliest countries to do so, and has since developed a regulated system for prescribing, producing and researching cannabis-based medicines. Israeli universities, hospitals and companies have produced a substantial body of clinical research on cannabis applications — a body of work that now influences medical practice internationally.
What the clinical evidence supports
The strongest clinical evidence for medical cannabis covers several specific conditions. Chronic neuropathic pain — pain from nerve damage that does not respond well to conventional analgesics — has shown consistent improvement in multiple controlled trials. Spasticity in multiple sclerosis responds to cannabis-based medicines, with a pharmaceutical preparation (nabiximols) approved in Israel and several other countries.
Epilepsy treatment, particularly for severe childhood-onset forms like Dravet syndrome, has shown dramatic results with CBD-dominant preparations. The pharmaceutical CBD preparation Epidiolex is now approved in multiple jurisdictions. For anxiety, the evidence is more mixed — clinical trials show benefit in some populations and settings, with the dose-response relationship being complex and context-dependent.
Beyond THC and CBD: the broader cannabinoid spectrum
Research attention has expanded beyond THC and CBD to other cannabinoids present in the plant — including CBG (cannabigerol), CBN (cannabinol), CBC (cannabichromene) and THCV (tetrahydrocannabivarin). Each interacts with the endocannabinoid system differently and may have distinct therapeutic applications.
Israeli researchers have been particularly active in this area. Studies have examined CBG's potential as an anti-inflammatory agent, THCV's effects on appetite and blood glucose regulation, and the "entourage effect" — the hypothesis that whole-plant preparations work differently from isolated compounds because the cannabinoids and terpenes interact with each other. This remains an active area of scientific debate, not yet settled clinical consensus.
Hemp cultivation and ecological dimensions
Hemp — the low-THC variety of Cannabis sativa grown for fibre, seed and cannabinoid extraction — has an ecological profile that compares favourably with many conventional crops. It grows rapidly without requiring pesticides in most conditions, has deep roots that can help prevent soil erosion, and sequesters carbon in both biomass and soil.
Hemp-derived honey — produced when bees forage on hemp flowers — is an emerging product at the intersection of ecological agriculture and therapeutic food research. Hemp pollen is a significant protein source for bees, and hemp-flowering fields provide foraging for bees in late summer when other pollen sources are scarce. This makes hemp cultivation a potential component of pollinator-support strategies in agricultural landscapes.
The regulatory landscape and what patients should know
Medical cannabis in Israel is legal and regulated through the Ministry of Health, with licences required for both prescribers and patients. Recreational use remains illegal. The regulatory system has expanded significantly since 2007: patient numbers, approved prescribers and licensed cultivators have all grown, and the range of approved preparations — oils, capsules, dried flower for vaporization — has broadened.
For patients considering medical cannabis, the critical step is consultation with a physician licensed in this area. Dosing, preparation type and cannabinoid ratio all affect outcomes and vary significantly between conditions and individuals. Self-medication with unregulated products — including many CBD preparations sold online — carries risks of inconsistent quality and no medical oversight. Israel's regulated system exists precisely to address these concerns.
