GO WITH AFP STORY by Desiree Martin A picture taken on April 12, 2013 shows plants of marijuana at the plantation of the Sibaratas Med Can association in Mogan on the southwest coast of the island of Gran Canaria. The plants grow from cuttings for approximately two months and then blossom before being harvested, dried, stored in jars for a month and later processed to be consumed on site. Spanish law prohibits the possession of soft drugs like cannabis in public and its growth to be sold for profit is illegal. But the law does tolerate growing cannabis for personal use and its consumption in private. Dozens of private marijuana smoking clubs operate across Spain that take advantage of this legal loophole that serve cannabis users who do not want to get their drugs from the streets.

A new study says there could be a surprising consequence to losing weight later in life

A colony of the soft coral known as the "bent sea rod" stands bleached on a reef off of Islamorada, Florida. Hard and soft corals are presently bleaching- losing their symbiotic algae Ð all over the coral reefs of the Florida Keys due to unusually warm ocean temperatures this summer. Months with waters warmer than 85 F have become more frequent in the last several decades compared to a century ago, stressing and in some cases killing corals when temperatures remain high for too long.

This illustration image shows tablets of opioid painkiller Oxycodon delivered on medical prescription taken on September 18, 2019 in Washington,DC. - Millions of Americans sank into addiction after using potent opioid painkillers that the companies churned out and doctors freely prescribed over the past two decades. Well over 400,000 people died of opioid overdoses in that period, while the companies involved raked in billions of dollars in profits. And while the flood of prescription opioids into the black market has now been curtailed, addicts are turning to heroin and highly potent fentanyl to compensate, where the risk of overdose and death is even higher.
