New heights but no high – why hemp sales are soaring – BBC News

Administrator Uncategorized 0

When Margaret MacKenzie heard that President Trump had legalised the cultivation of hemp across the US just before Christmas, she immediately thought: “Oh boy, here we go! Things are going to move very fast.”

The Colorado farmer tends to about 15 acres (six hectares) of hemp, the species of the cannabis plant that doesn’t have any psychotropic effect – it cannot be used to make a person “high”.

Hemp, or cannabis sativa, to give it its Latin name, is the straitlaced cousin of cannabis indica, which is better known as marijuana.

Unfortunately for hemp, being a near-relative and lookalike of marijuana has meant that it has always been tarnished by association.

So while hemp is a very useful crop that can be turned into everything from clothes to shoes, paper, animal feed and building insulation, the cultivation of it was banned in many countries during the 20th Century.

In the US it was outlawed in 1970 by President Richard Nixon, and that remained the case until December last year, when the Agriculture Improvement Act of 2018 was passed into law.

Hemp farmers such as Ms MacKenzie now expect US production to skyrocket, and industry estimates back that up.

Sales of hemp products in the US reached $1bn (£760m) in 2018, according to New Frontier Data, which specialises in reports on both types of cannabis. Imports account for most of this figure, but the US Drug Enforcement Administration had allowed some pilot growing schemes under strict licence since 2014.

New Frontier Data expects US sales of hemp products to reach $2.6bn by 2022. At the same time it predicts global hemp industry sales to jump to $5.7bn by 2020, from $3.7bn in 2018.

Cannabis facts

  • The chemical compound in marijuana that makes a user high is called tetrahydrocannabinol or THC. Hemp contains a trace amount of THC, but not enough to make a person high
  • Advocacy group Ministry of Hemp says: “Your lungs will fail before your brain attains any high from smoking industrial hemp”
  • While hemp can now be grown legally across the US without a licence, marijuana can be cultivated only in about half the states, often only under licence and solely for medical use
  • Hemp farming has a long history in the US, with first President George Washington growing the crop
  • In the UK you need a Home Office-controlled drug licence to be able to grow hemp
  • Cannabis plants are native to central Asia
  • Hemp can grow up to 20ft or six metres high, twice as tall as marijuana

Why are so many countries now saying cannabis is OK?

Soaring demand worldwide for a key chemical compound called cannabidiol or CBD, which is found in the flowers of the hemp plant, is behind the growth.

CBD – which is also present in marijuana, but does not make the user high – helps to treat epilepsy. As such it is used to make epidiolex, an anti-epilepsy drug that is now prescribed in both the US, and by the National Health Service in the UK.

However, sales of this drug are dwarfed by the growing popularity of consumer products containing CBD, due to the belief that it can treat a range of other health problems, from pain to inflammation, anxiety and even cancer.

So on both sides of the Atlantic you can now buy everything from CBD-infused coffees and teas, to skin creams, lip balms, sweets and even bath bombs.

“Once more consumers get educated about CBD, that’ll drive more demand,” says Elliot Brown, another Colorado hemp farmer.

Mike Lewis, a hemp farmer in Kentucky, agrees that CBD production is now going to lead the hemp industry as opposed to the crop’s industrial uses.

“Everyone in the hemp industry is turning to CBD because that’s where the money is,” he says.

Whether CBD and products containing it actually do have widespread health benefits, or could in fact harm you over the longer term, is still being debated in the medical community, as the Guardian newspaper reported last year.

In the meantime the boom in demand for hemp is good news for the US environment because the fast-growing and hardy plant needs very little water, and therefore requires far less irrigation than corn, wheat or soybeans in dry areas.

Hemp plants can also be planted very close together, making it high yielding. And unlike marijuana, whose plants are half as tall and have bigger leaves, hemp isn’t fussy about temperature and humidity.

China is currently the world’s largest exporter of hemp products, but the US industry wants to change that.

Global Trade

More from the BBC’s series taking an international perspective on trade:

“At some point we’ll see American hemp production eclipse China,” says Bob Hoban, a commercial lawyer who represents growers of both types of cannabis across the US.

“We’re already seeing a massive investment in production infrastructure, and that takes time.

“We’ll eventually reach the point where hemp will not just appeal to the cannabis industry and their consumers.”

However, Erica Stark, executive director of the National Hemp Association, cautions that the industry needs to walk before it can run.

Last year just 78,176 acres of land in the US was planted with hemp, compared with 47 million acres dedicated to wheat, and 90 million acres to both soybeans and corn.

“The danger we’re facing now is over-enthusiasm,” says Ms Stark. “We just don’t have the infrastructure to go into full commercial production. Yet.”
