Millions of people will celebrate International Marijuana Day, which calls for legalizing the private use of the cannabis plant, in over 150 cities throughout the world. In Yarkon Park in Tel Aviv and Sacher Park in Jerusalem, Israelis will gather for the ninth year in a row for a mass picnic in honor of the day. The heads of the Green Leaf Party, along with other cannabis legalization activists, were expected to speak at the gatherings. The chairwoman of the Al-Sam anti-drug organization, Liora Ofer, submitted an urgent appeal to the High Court of Justice last Thursday in which she demanded that the court prevent minors from participating in the day's activities. Ofer also demanded that police check for drugs at the entrances to the gatherings.
