China to cash in on cannabis boom…

 Tea to smoking over 5,000 years…

Almost 5000 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 moves to legalise, 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 Organisation (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 recognised.

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.

Last month, Uruguay became the first country to legalise marijuana in its entirety – from growing the crop to processing and use. Now Peru looks likely to follow Uruguay’s example and legalise cannabis production.Last week, the US state of Colorado decriminalised the recreational use of cannabis. Stores may have turned over up to US$1 million ($1.2 million) statewide during the first day alone, according to shop owners. The Department of Revenue for Colorado said sales could hit US$600 million by the end of this year.

People in Washington state have also voted to legalise marijuana, although stores are not expected to open until later in the year.

The New York Times reported that New York is planning to loosen its marijuana laws to allow limited use of the drug by people suffering serious illness. The newspaper said Governor Andrew Cuomo – a long-time opponent of legalising medical marijuana – was planning to announce the new guideline this week in an executive action.

New York would become the 21st state to allow medical use of marijuana. California has already loosened its rules on medical marijuana.

Shares in companies involved in cannabis soared after Colorado’s move. One firm, MediSwipe Inc, had its stock jump by nearly 70 per cent last Thursday. The legal trade in cannabis in the US alone could be worth US$10 billion by 2018.

Analysts say China is once again at the forefront of exploiting new economic opportunities.

“Because cannabis in Western medicine is becoming accepted, the predominance of Chinese patents suggests that pharmaceutical sciences are evolving quickly in China, outpacing Western capabilities,” Dr Luc Duchesne, an Ottawa businessman and biochemist, wrote in InvestorIntel.

“CTM [Chinese traditional medicine] is poised to take advantage of a growing trend. The writing is on the wall: westernised Chinese traditional medicine is coming to a dispensary near you.”

Many of the Chinese patents are for herbal treatments. One, filed by the Yunan Industrial Cannabis Sativa Co, refers to an application made from whole cannabis sativa seeds to make “functional food” designed to improve the human immune system.

Another, by an inventor called Zhang Hongqi, is for a “Chinese medicinal preparation” for treating peptic ulcers. It uses an array of ingredients, including cannabis sativa seed. The filing says it has “significant therapeutic effectiveness and does not cause any adverse effect”.

There is also a patent filing from China for a treatment for constipation, which is made using fructus cannabis and other ingredients such as “immature bitter orange”, Chinese angelica and balloon flower. This, it is claimed, treats constipation’s root causes and symptoms.

However, only one company in the world has developed cannabis-based drugs as medicines that have been recognised by regulators in the West following the long, costly process of clinical trials. GW Pharmaceuticals, based in Wiltshire, England, makes Sativex for the treatment of symptoms of multiple sclerosis and cancer pain, and Epidiolex for childhood epilepsy.

A spokesman for the company, which is the only one licensed to carry out research on cannabis in Britain, said China had a long history of working with herbal medicines.

“In that sense it doesn’t come as a surprise,” he said of the patent filings. “This is a country with thousands of years of working with plants in medicines.”

In December, Jamaica announced it was forming its first medical marijuana company, called MediCanja. Henry Lowe, a scientist and executive chairman of MediCanja, said medical cannabis could help “transform Jamaica’s fledgling economy”.

“Given Jamaica’s history with ganja, we could be the hub for medical ganja in Latin America and the Caribbean.”

Peter Reynolds, leader of Cannabis Law Reform (Clear), a British-based campaign group, said China had another advantage over other countries in selling cannabis as it was one of the largest producers in the world of industrial hemp, a form of cannabis with a low amount of the psychoactive compound THC.

“The Chinese are smarter and they are on to all the good ideas,” he said. “The potential for cannabis as a medicine is monumental.”

But smoking cannabis remains illegal in China. In April last year, the South China Morning Post reported that it was a popular drug among the country’s young people despite the threat of lengthy prison sentences.

The opening up of a legal trade in non-medical marijuana is not without its critics. Uruguay’s decision to remove all legal restrictions on use was condemned by the International Narcotics Control Board, the body charged with monitoring international treaties on narcotics.

“Cannabis is not only addictive but may also affect some fundamental brain functions, IQ potential and academic and job performance, and impair driving skills,” it said. “Smoking cannabis is more carcinogenic than smoking tobacco.”
