Campaigners dropped cannabis in Tel Aviv using a drone
"Green Drone" had pre-announced a drop of hundreds of bags, each containing two grammes (just under a 10th of an ounce), on central Tel Aviv's Rabin Square.
"It's time, dear friends. Is it a bird? Is it a plane? No, it's Green Drone distributing free cannabis from the sky," it said on its Telegram channel, quoted in Israeli media.
It urged followers to roll up for further dope drops every week at different locations around Israel, although police arrested two alleged drone operators on Saturday.
Israeli smokers often use encrypted messaging apps to order weed deliveries, although the drug is illegal in the Jewish state.
Medical use of cannabis is allowed but Israeli police frequently boast of drug busts.
Researchers said in June that it was highly likely that ancient Israelites got high on cannabis in religious rituals, after researchers found traces of the drug at a religious site in Israel.
Eran Arie, curator of Iron Age archaeology at the Israel Museum in Jerusalem and lead author of a study, said the discovery was "revolutionary", as it was the earliest evidence of cannabis use in the ancient Near East and the "first time we see psychoactive substances in Judahite religion".
"Here, the official state religion of the kingdom of Judah was using this substance," Arie said.
Because of the site's clear connection to the monarchy, he suggests it could point to how worship was conducted in the biblical Temple in Jerusalem.
