Iemma to introduce hydroponic cannabis legislation based in wives’ tales
Saturday February 04th 2006, 9:06 am

image: bbc.co.ukNSW Premier Morrris Iemma is set to introduce legislation to the NSW Parliament increasing penalties for growing cannabis with hydroponic means. Iemma has been sucked in by the fear campaign run by anti-cannabis campaigners over the supposed "7 times greater stength" of cannabis grown by hydroponic methods. The greater strength of ‘modern’ cannabis is quoted by anti-drug pressure groups as anywhere between a few times to up to 50 times (or more) the strength of cannabis grown in the 1960s.

Hydroponics is a means of delivering fertiliser to the roots of a plant in a liquid form, while the plant’s roots attach themselves to an inert material (such as gravel or lava rock) to hold the plant upright, instead of growing the plant in conventional soil. The plant simply gets its food from a liquid nutrient solution instead of extracting it from organic fertilisers contained in soil.

The characteristics of any plant- flavour, colour, size, shape, and in the case of cannabis, the psychoactive ingredient content- are determined by its particular DNA structure. Hydroponic growing does not alter the DNA of a plant any more than feeding a person intravenously will change that person’s eye colour.

Tomatoes and lettuce are also commonly commercially grown with hydroponic techniques.  Tomatoes are no more tomato-y nor is lettuce any crisper when grown with hydroponics. In the same context, cannabis is no stronger simply because it has been grown with hydroponic techniques. Strangely, ‘hothouse’ or hydroponically grown tomatoes and lettuce are not similarly in the sights of legislators.

The "Not Your Father’s Marijuana" myth is repeated constantly by anti-drug campaigners- but not because it is the truth. Such misinformation merely suits the goals of the pressure groups. Cannabis has not suddenly become dangerous in the last few years. Anti-cannabis pressure groups are simply now getting the ears of politicians with the ‘hydroponics!!‘ buzzword.

The justification proffered by anti-drugs campaigners that ‘modern’ cannabis is ‘X’ times stronger than that smoked by hippies in the 1960s & 70s is based in data collected by the US DEA from seized cannabis. The DEA did in fact record an upward change in the content of the psychoactive component in cannabis, but it wasn’t because of any miraculous discoveries in hybridising, genetic engineering or cultivation methods.

Most of the psychoactive delta-9 tetrahydrocannabinol (THC) component in cannabis is contained in the flowers or ‘buds’ with next to none contained in the leaves, stems and seeds of the plant. Dried cannabis seized by the DEA in the 1960s and 70s contained not just the flowers but also the largely inert leaves, stems and seeds. Cannabis users through the 1980s expressed a preference to buy only the buds, so growers began to discard the inert material. When DEA seized cannabis in the 1980s and forward, the amount of THC measured by weight appeared to increase when compared to earlier seizures which included the inert materials. If the statistics are corrected to reflect the omission of inert material, cannabis from the 1960s is virtually identical to ‘modern’ cannabis. The DEA did not discover any new ‘super cannabis,’ but rather tracked a user preference trend.

Premier Iemma should get on the phone to people who have real scientific knowledge about cannabis, like Dr Alex Wodak of Sydney’s St. Vincent’s Hospital Drug and Alcohol treatment unit, instead of listening to fearmongering pressure groups. However, hard scientific data about cannabis is hard to come by because governments often refuse to fund proper research.

Let’s base our drug laws in replicatable scientific facts rather than in scare campaigns.

I pray for legalisation so I can see if smoking cannabis relieves my chronic neuropathic pain which is resistant to analgesics and opioids.
Water is a much more important issue for the NSW State Govt – maybe Iemma is trying to save water by clamping down on hydroponics.

I don’t know anything about the science of it but I would swear that there is a huge difference between hydro and natural, both in quality and strength.

When people are caught with it, charges should be laid based on total THC rather than weight of the plant matter. Under current laws you could have an old bag of useless leaf lying around and get done for dealing.

Brownie, you may recall that Bob Carr at one time laid out a grand scheme for a medicinal cannabis trial- but then nothing happened.

Manicboy, thanks for popping in. There is a difference between outdoor & indoor, but that mainly has to do with the fact that there’s never a cloudy day under artificial lighting. Also, there is no stray pollen floating around to fertilise the female flowers. It is the unfertilised, seedless female flowers that have the greatest potency.

However, if you grew two female plants with the same DNA, one indoors with hydroponics and one outdoors in soil, the difference in potency would be within a few percentage points of one another. Hydroponics isn’t magic. It certainly doesn’t give you anything 10-20 or 100 times stronger than 1960s marijuana, as the anti-cannabis lobby would have lawmakers and frightened parents of teens believe. The truth just isn’t scary enough for the pressure groups.

Yes, there’s advantages to growing indoors, but ask the folks down in South Australia who can legally grow a few plants about how often their backyard plants are stolen- and you suddenly find the main reason why they prefer to grow indoors in hydroponics!

A great overview of the politics and the science is over here.

Thanks for that, Margie.

Let’s see if Iemma is content to take the word of wowsers or if he’ll delve into the replicatable science. That will tell the tale if our new premier is an arbitrary authoritarian or not.
