Greg Soar swallows 98 each week, a powdery, foul-tasting cocktail that represents his best hope of slowing the virus that is replicating inside him and staving off the onset of full-blown Aids, perhaps for several more years. Unfortunately for Soar, the pills produce extremely unpleasant side-effects. Worse still, the one substance that offers some relief - easily administered, effective relief - could put him behind bars. Those pills. "They make me sick with severe nausea; I can't sleep, I get uptight, anxious; I can't eat and so I get diarrhoea from taking the pills on an empty stomach." He was offered heavy tranquilisers - more pills - he was given anti-nausea medication. Been there, got addicted. Not so with cannabis. "Two puffs on a joint or a couple of tokes on a vapouriser and it's instant nausea relief. It's gone." Soar's GP is happy to oversee his use of the herb. "We've nothing better to offer him," concedes Dr Arvind Ranvhhod. "It's a shame that Greg has to break the law to help himself and it's a shame that he has to pay an artificially inflated price for it. Because of his limited means he's not guaranteed a regular supply of the medication." Soar's friends help out; he buys as often as he can afford to. If worse comes to worse, he could always risk prosecution and grow his own. But there is a better option. Under the Misuse of Drugs Act, Soar can apply to the Minister of Health, Annette King, for an exemption. Twice he has written, backed up by a second GP and a specialist in infectious diseases, asking the government to supply him with what he considers to his "best medicine", or failing that for permission to grow six female marijuana plants, or at least for the threat of arrest and imprisonment to be lifted. Two replies from King, same response: in the absence of clinical evidence that cannabis is safe and effective, she will not be granting any dispensation. King says she has received four applications to use marijuana therapeutically, all declined. One of those is from tetraplegic Danuiel Clark, jailed for 21 days in 1999 for cannabis cultivation, and this month facing a charge of possession for personal use. Soar, who is likely to protest with a group of supporters at Clark's trial, asks the obvious: what's the point of a power to exempt if it's never exercised? "The fact that we're not allowed to use cannabis when everyone is using it for social reasons is completely obscene to me. Prohibition is causing more harms than people realise." An empty gesture? King defines her powers narrowly: she is able to approve a doctor to prescribe a drug from the category to which cannabis belongs. She argues that none of the applications she has received, including Soar's, has met the necessary "clinical criteria" - although she is unable to define those particular hurdles. Her strongest objection is apparently reserved for the likely form of delivery. "People have asked me to [let them] smoke cannabis. One of the problems with smoking is that you don't know what your dosage is. It's also bad for your health." The line leaves NORML's Chris Fowlie aghast. "For someone to say we can't have a medicine that involves smoking, and that that outweighs your quality of life is pretty narrow-minded." Fowlie argues that in the absence of a non-smoking device that would deliver cannabinoids to the lungs - far more efficient at metabolising THC than the stomach - smoking is actually the best way of regulating a dose, better, for example, than Marinol, a pill form of THC available overseas. King's attention is on the bigger policy picture, and particularly a couple of overseas clinical trials into the possible therapeutic uses of cannabis derivatives - "that's of more interest to me than some exemptions." Possible scenarios? "If you're talking about marijuana being used for medicinal purposes, then you're talking about it being put in the same regime as morphine, or whatever: registered, prescribed and managed by people trained in these matters. It would be done in the same way that we'd register any medicine in New Zealand." In other words, we're talking tinctures, capsules, pills - the pharmaceutical route. In essence, then, Soar and others are left waiting on those overseas clinical trials and on a kindling of interest among drug companies, traditionally wary of cannabis's illegal status and the fact that the raw product itself can't be patented. Most likely, they are waiting on researchers to find a means to separate the buzz from the source of the therapeutic effect - to remove the stoner's high from the argument. Green Party MP Nandor Tanczos believes King is "hiding behind" the wait-and-see argument. "We don't need to synthesise a pill and buy it off some pharmaceutical company for millions of dollars and then have a doctor prescribe it. We just really need some recognition that these people shouldn't be arrested for growing their own medicine and using it." King seems unlikely to allow a doctor to prescribe cannabis unless as part of a "properly conducted" trial. Okay, says Ranvhhod: "Greg would be more than happy to be a guinea pig if that's what they need!" But joking aside, his own expert opinion should be all the "clinical evidence" required. Of course, his patient is aware of the potential risks of smoking. "But he's looking at the quality of his life now, not some long-term future. It really shouldn't be such a hurdle if we think that it's his best treatment." NORML would go a step further. "Self-medication has to be an interim step," says Fowlie. "Not everyone can grow their own, and those who do are at risk of being robbed for their medicine." The future of medicinal marijuana isn't in extraction or synthesis, but growing specific strains of the raw plant for specific ailments, he believes. "What we'd be after would be a proper supply of cannabis in the prescription system." The mystery of physics: Ranvhhod hasn't a clue why cannabis seems to be the best answer to Soar's symptoms. "Greg and I are interested in the effect, rather than how or why it works," he says. But medical science is learning more about the therapeutic potential of THC and the various other cannabinoids (there are more than 60) found in the plant. Both the US National Institute of Health and the British Medical Association have reported that cannabinoids may be useful as analgesics, anti-emetics, anti-spasmodics and appetite stimulants. Even deeper in the heart of the Establishment, a select committee of the House of Lords has itemised the conditions for which marijuana may hold therapeutic potential, namely: HIV-related and cancer-related wasting; pain unrelieved by conventional treatments; symptoms of neurological disorders such as MS; nausea and vomiting in cancer patients undergoing chemo. Of interest to Soar, a University of California study has found that patients on HIV medication who smoke cannabis do not have their immune systems suppressed and experience significant gains in calorie intake and weight. There is some political movement, too. In the US, several states have allowed the medicinal use of marijuana (butting heads with federal authorities; at press-time the Supreme Court was to rule on the conflict). The Spanish Catalan parliament is to consider it; and in Canada, where the prosecution of medicinal users threatens to invalidate federal drugs laws, the Minister of Health has authorised a number of applicants to use the plant. The Australian example is arguably most relevant. New South Wales authorities are considering how to implement a recommendation from the National Drug and Alcohol Research Centre (NDARC) that seriously ill patients be given exemption to smoke. NDARC's report recognises that the development of synthetic cannabinoids or approved alternative methods of delivery is at best several years away. In the meantime, it proposes, anyone who can provide medical certification that they suffer from certain conditions (those same illnesses recognised by the House of Lords committee) should be allowed to grow as many as five small plants. "Cannabis is not a first line treatment," says Professor Wayne Hall, executive director of NDARC. "For most of these conditions there are other forms of treatment that are likely to be much more effective. But for some individuals who don't respond to conventional treatment it could be life saving." He cites chemo patients whose side-effects can get so bad that they quit their treatment regimes. As things stand, many of these patients will be in their 60s and 70s and unable or unwilling to access cannabis through the black market. "I don't think any sensible, humanitarian-minded person would want to prevent people with those conditions having access to it." Participants in the scheme will be monitored at six monthly intervals. The downsides? The potential harms of smoking is the only major one that he can see. "People talk about diversion, but that's not something that one would take seriously given how readily available the drug is now. I also think it's pretty unlikely that it'll do much to affect attitudes towards the recreational use of cannabis - it needn't if the government is very clear and explains what it is doing." "And", he adds, "given that people are likely to be doing it anyway, isn't it better that they should be doing this under medical supervision with the opportunity to pick up on any adverse effects?" Yet, this side of the ditch, the Ministry continues to say no. Is this about sending a message? Not at all, answers King. A Health select committee is to report later this year on decriminalisation, but the herb's therapeutic potential will not be on the agenda. "Personally, I don't want to see it mixed up in that wider debate about marijuana. I would have thought people who seriously consider it a good medicine wouldn't want it mixed up in there, either." Fowlie doesn't see how the two can be divorced. "Admitting that cannabis has therapeutic effects [undermines] the whole justification for prohibition. They believe it will open the door and that's a valid fear, because it will. This is a prime example of prohibition causing a huge amount of unnecessary harm." NORML is spoiling for a fight. To date, courts in New Zealand haven't accepted the defence of possession for medicinal purposes. But British juries have acquitted, and Canadian courts have ruled that prohibition, overly broad in its application, goes against the individual's right to the best possible medicine. Fowlie, who argues that New Zealand drugs law was only ever aimed at stamping out recreational abuse not medicinal use, believes that such a legal attack might be mounted here. "Human rights legislation guarantees access to the best possible treatment," he says. Alternatively, the next time Soar is knocked back, someone with a flush wallet might want to fund a writ for judicial review. The next visiting cannabis-friendly billionaire, perhaps? - --- MAP posted-by: Beth
