Global Ganja Report

For the second year in a row, Brazil has witnessed a deadly prison riot on the first day of the year. A death toll of nine is reported from the central state of Goias. One inmate was decapitated. The violence began New Year's Day afternoon at the rural penitentiary in the outskirts of the state capital, Goiania. Rival criminal factions clashed, broke the barriers of the compound and escaped, by the BBC News account.

Brazilian federal police on Dec. 28 announced the arrest of José González Valencia, one of the top leaders of the Jalisco New Generation Cartel (CJNG)—the criminal machine that in recent years has risen to challenge the Sinaloa Cartel for control of Mexico's narco trade. Valencia, known as "Chepa" or "El Camarón" (The Shrimp), was arrested at Aquiraz, a resort near the coastal city of Fortaleza, where was spending the Christmas holidays with his family. Authorities said Valencia had been living in Bolivia for two years after fleeing Mexico, and had entered Brazil as a tourist on a Bolivian passport.

Back in September, Brazilian army troops were deployed to quell fighting between rival drug gangs in Rocinha, the most notoriously violent of Rio de Janiero's favelas—the informal urban settlements in the north of the city, virtually abandoned by the government for anything other than militarized anti-drug operations. On Dec.

Brazil's ongoing favela wars have taken a dramatic turn for the bloody—prompting the government to send military troops into Rio de Janiero's notorious Rocinha. This is the most violent of the city's sprawling favelas—informal urban settlements virtually abandoned by the government for anything other than militarized anti-drug operations. The army on Sept. 22 deployed nearly 1,000 troops in Rocinha, responding to a request from the Rio state government, Defense Minister Raul Jungmann told local TV.

The First Argentine Congress on Cannabis and Health was held last week at the National University of La Plata (UNLP), bringing together academics, activists, cultivators and patients from across the Southern Cone country. The focus was on expanding the extremely limited medical marijuana law passed in Argentina earlier this year. At the opening ceremony, held in an auditorium within La Plata's provinicial legislature building, UNLP president Raúl Perdomo pledged to "work to make the regulations for the recently approved law include the national universities in cultivation and research."

Amid fast-escalating nightmarish narco-violence in Brazil comes disconcerting word that police in Rio de Janeiro seized 60 assault rifles hidden in a shipment of swimming-pool heating equipment that had just arrived on a flight from Miami. Pulse News Agency reported June 2 that the AK-47s and AR-10s were discovered in the cargo terminal of Rio's international airport. Photos of the haul showed weapons in the foam packaging they were flown in.

The medical marjuana advocacy organization Mamá Cultiva, which has been campaigning on the issue across South America, is criticizing the new measure just passed by Argentina's Senate for failing to legalize personal cultivation. The Senate voted unanimously on March 29 to legalize cannabis oil and other derivatives for medical purposes. Talking Drugs blog reports that the bill is set to become law immediately upon receiving President Mauricio Macri's signature, as it was already passed by the lower-house Chamber of Deputies in November. Under the law, patients must register with a planned national program to be overseen by the Ministry of Health.

Yet another deadly prison riot is reported from Brazil. This time, rival gangs clashed for control of a pavilion at Alcaçuz State Penitentiary, in the northeastern state of Rio Grande do Norte. The riot began early Jan. 14; police surrounded the prison that night, but waited until noon the next day to enter due to reports that rebel inmates had armed themselves. At press time, the state’s military police and elite Special Operations Batallion are trying to negotiate the surrender of the inmates, according to Brazilian news blog Plus55. The state government has confirmed at least 10 deaths, but the number is expected to rise—Reuters already puts it as high as 30. Some of the victims are said to have been decapitated.
