CHINA: Almost 5,000 years ago, Chinese physicians recommended a tea made from cannabis leaves to treat a wide variety of conditions including gout and malaria. Today, as the global market for marijuana experiences an unprecedented boom after being widely legalized, it is China that again appears to have set its eyes on dominating trade in the drug.
The communist country is well placed to exploit the burgeoning cannabis trade with more than half of the patents relating to or involving cannabis originating in China. According to the World Intellectual Property Organization (Wipo), Chinese firms have filed 309 of the 606 patents relating to the drug.
About 147 million people – around 2.5 per cent of the world’s population – use cannabis, according to the World Health Organisation. And medicinal properties of the drug are increasingly being recognized. It can be used to treat conditions ranging from the nausea caused by chemotherapy for cancer patients and chronic pain to cerebral palsy, multiple sclerosis and epilepsy.
