SAFED, Israel — Among the rows of plants growing at a government-approved medical marijuana farm in the Galilee hills in northern Israel, one strain is said to have the strongest psychoactive effect of any cannabis in the world. Another, rich in anti-inflammatory properties, will not get you high at all.

Marijuana is illegal in Israel, but farms like this one, at a secret location near the city of Safed, are at the cutting edge of the debate on the legality, benefits and risks of medicinal cannabis. Its staff members wear white lab coats, its growing facilities are fitted with state-of-the-art equipment for controlling light and humidity, and its grounds are protected by security cameras and guards.

But in addition to the high-tech atmosphere, there is a spiritual one. The plantation, Israel’s largest and most established medical marijuana farm — and now a thriving commercial enterprise — is imbued with a higher sense of purpose, reflected by the aura of Safed, an age-old center of Jewish mysticism, as well as by its name, Tikkun Olam, a reference to the Jewish concept of repairing or healing the world.

There is an on-site synagogue in a trailer, a sweet aroma of freshly harvested cannabis that infuses the atmosphere and, halfway up a wooded hillside overlooking the farm, a blue-domed tomb of a rabbinic sage and his wife.
