For nearly a century, we have been sold a lie: that petroleum-based products are the pinnacle of modern innovation. Meanwhile, a plant offering a sustainable path forward for industry, construction, and agriculture has been deliberately criminalised and mocked. It is time to expose the undeniable truth about Cannabis Hemp – not as a recreational drug, but as one of the most versatile, economical, and environmentally restorative resources on the planet. This is a perfect example of a system where a superior solution has been suppressed for decades to protect entrenched, polluting industries.
Industrial hemp, a variety of Cannabis sativa with negligible THC (Tetrahydrocannabinol), is not a new crop but a forgotten one whose potential applications are staggering. In construction, a material called Hempcrete – a mixture of hemp hurds and a lime binder – is a revolutionary, carbon-negative building material. It is lightweight, non-toxic, resistant to mould and fire, and provides excellent insulation, offering a stark contrast to energy-intensive concrete, which is responsible for a staggering 8% of global CO2 emissions. Beyond building, hemp fibres can create durable, fully biodegradable bioplastics for everything from packaging to car interiors. Research from the University of Bologna confirms that hemp-based composites are strong, lightweight, and sustainable, providing a viable alternative to fiberglass and carbon fibre. In the textile industry, hemp fabric is stronger, more absorbent, and more durable than cotton, while crucially requiring 50% less water and no pesticides. Furthermore, for paper production, hemp yields four to five times more pulp per acre than trees and can be harvested in just 120 days, not 20 years, offering a clear path to drastically reduce deforestation.
When we examine the environmental and economic ledger, the comparison between hemp and petroleum is not even a contest. Hemp-based products are carbon negative, meaning they sequester CO2 as they grow, while petroleum-based products are carbon positive, acting as a major emitter of greenhouse gases. Hemp has low water requirements and is drought-resistant, whereas petroleum extraction and refinement are notoriously water-intensive. At the end of their life, hemp products are biodegradable and non-toxic, even leaving the soil healthier, while petroleum-based plastics create persistent pollution that lasts for centuries in the form of microplastics. The remediation cost for hemp is low to none, as the plant can be used for phytoremediation to clean contaminated soil. In stark contrast, the cost for petroleum is extremely high, with billions spent on oil spill cleanups and landfill management. Finally, hemp is an annually renewable resource harvested in a single season, while petroleum is a finite resource whose scarcity has sparked countless geopolitical conflicts. On every single metric – carbon footprint, water usage, end-of-life impact, remediation cost, and renewability – hemp is the undisputed winner.
The opposition to this miracle crop has never been based on science or public good, but solely on protecting established profits. Historically, the push to criminalise hemp in the 1930s was led by a powerful trio: William Randolph Hearst, who had significant timber and paper interests; the DuPont corporation, which had just patented nylon and petrochemical processes; and Harry Anslinger of the Federal Bureau of Narcotics. Their weapon was a campaign of racism and fear-mongering, deliberately tying industrial hemp to its psychoactive cousin and popularising the term “marijuana” to stoke xenophobic fears. Today, the modern opposition continues from a similar coalition: the synthetic fibres and plastics industry, which is reliant on petrochemical feedstocks; Big Pharma, which fears the medical and wellness applications of cannabinoids; the private prison industry, which profits from non-violent drug offenses; and the alcohol and tobacco industries, which view cannabis as a direct competitor.
Their arguments, however, are easily debunked. The claim that hemp is a “gateway drug” is a deliberate and flawed conflation of industrial hemp, which contains only 0.3% THC and has no psychoactive potential, with high-THC cannabis. This argument is a pure relic of the 1930s propaganda campaign. The assertion that it is “not economically viable” is a self-fulfilling prophecy; decades of prohibition have stifled the very research, infrastructure, and economies of scale needed to make it viable. In fact, when allowed, the market flourishes, as demonstrated by a 2022 report from the Brightfield Group that projects the U.S. hemp market will reach $5.7 billion by 2027. Finally, the argument that hemp will “harm the existing agriculture or forestry sector” is the classic lament of obsolete technology, akin to the buggy whip maker arguing against the automobile. Hemp actually offers farmers a profitable, drought-resistant rotation crop that improves soil health, reducing their dependence on government subsidies and chemical inputs.
The cost of our continued inaction – of relying on petroleum while suppressing hemp – is astronomical. The environmental cost includes accelerated climate change, pervasive microplastic pollution, and ongoing deforestation. The economic cost runs into the billions, spent on environmental remediation, addressing the health impacts of pollution, and military spending to secure volatile oil supplies. And the social cost is seen in the lost opportunities for rural economic revival and sustainable job creation in green manufacturing.
We stand at a crossroads. We can continue to prop up a 20th-century industrial model that is poisoning our planet and concentrating wealth, or we can embrace a 21st-century solution rooted in a plant that cleans our air, builds our homes, and creates a circular, restorative economy. The evidence is clear and the path forward is green. It is time to end the prohibition on progress and unleash the full power of hemp.

Hopeful thoughts, Andrew: It is time to end the prohibition on progress and unleash the full power of hemp: An inspirational article. I look forward to some more cheer for the season.
Is it illegal to grow industrial grade hemp in Australia or is that there is no interest in financing the establishment of hemp harvesting and processing industries?
Mediocrates, a google query furnishes a raft of information. Hemp is grown in every state in Australia, with Tasmania and NSW leading the charge. The industry kicked off seriously in 2017 after the passing of Industrial Hemp Act, which enabled the way for primary producers to cultivate under licence. Of interest is that hemp arrived with the First Fleet in 1788, with the botanist Joseph Banks recommending that the new colony be used to grow hemp to supply the British Empire’s need for durable fibers for maritime use.
I agree with this article with one exception, it wasn’t the petroleum industry that opposed hemp production, it was in fact America’s cotton industry.
Stop making sense Andrew,that is anathema to our career pollies and big business.Think of the profits they’d have to forgo.
jonangel…confirm your view please. Facts matter as much as if not more than opinions.
On public record is the well-known fact that post-prohibition, circa 1933, Harry Anslinger, the head of the Federal Bureau of Narcotics, and the bureaucrat charged with enforcing prohibition laws, was concerned he’d run out of a cause to prosecute. He was known to be a zealot and rabidly anti-drug use of whatever kind, and he pinged on the idea of banning cannabis in all its forms, and was foremost in the creation of the 1937 Marihuana Tax Act… an act that effectively criminalized hemp by making it too costly and difficult to grow, despite hemp’s industrial uses.
Contrary to your claim, it was the timber, nylon (DuPont), and paper industries that saw hemp as a threat to their products and lobbied for its restriction.
Anslinger was deeply racist, and believed that smoking weed led to reefer madness and that African Americans, the primary users, would seek out white women to molest and rape. A classic case of having the worst sort of person granted licence to prosecute his views, similar to the cross-dressing closet gay head of the FBI, J. Edgar Hoover.
This leads me to another thing our incompetent health minister has stuffed up.
My doctor prescribed me medical marijuana about 18 months ago (I suffer from intensely chronic nerve pain). The only medication that work for this type of pain are the old fashioned antidepressants – which deaden the nerves – but I’d have to take a fairly large dosage: enough to turn me into a zombie made of jelly.
Bugger that. Dope sounded better. The doctor recommended I use a dry herb vape, which was the preferred choice of medical marijuana users. Instead of smoking the dope – inhaling smoke – with the dry herb vape I’d be inhaling steam. Much more pleasant and equally effective.
At about the same time, the government banned vaping and also made dry herb vapes illegal. Goodness – couldn’t have someone using their medical marijuana dry herb vape or they might be tempted to vape. Gosh no.
So I had to smoke it. One drag and I spent the next half hour coughing my lungs up.
Good one, Mark Butler. Not.
PS: The TGA approved one type of dry herb vape only. The catch? They cost just under $1,000. Bugger that.
I am often wrong, but the invention of the cotton gin and the ease of dyeing, plus the introduction of Marihuana Tax Act of 1937 were the main causes of the decline in hemp production. The support of the Southern states was also a factor.
This had a flow on effect here in Australia.
Smoking it definitely f..ks with your chest…
The government is at its worst when it comes to the contemplation of new ideas.
The only tropes and memes it seems to be able to follow are outdated ones.
Michael,
the best course of action is not via your precious lungs, smoke or steam, you have to watch out for particulates and tars. The best course of longer-lasting action is via your digestive system. Either a coupla drops under the tongue, or eating delights made with appropriately enriched butter. Most GPs will know about this, and could legally accommodate your needs. It obviates any need for steam distillation paraphernalia.
We need politicians with vision. This issue has been kicked down the road for generations.
Sadly, the only vision on either side of politics at the moment is whether their share portfolio outstrips their real estate portfolio.
“one of the most versatile, economical, and environmentally restorative resources on the planet.”
Indeed, and have known that for years! Says a lot about biases, and not just about Hemp either, the same can be said for medical hemp, which has been a long-fought war because Medical and big pharma wants to control everything! Can’t let those profits walk away now, can we.
Can’t have people knowing how they can take care of themselves and their families can we.
