Cannabis can reduce spasticity in multiple sclerosis (MS) patients. A systematic review, published in the open access journal BMC Neurology, found that five out six randomized controlled trials reported a reduction in spasticity and an improvement in mobility. http://www.physorg.com/news179118127.html Medicine & Health Fri, 04 Dec 2009 03:30:01 EST news179118127 Substituting cannabis in place of more harmful drugs may be a winning strategy in the fight against substance misuse. Research published in BioMed Central' open access Harm Reduction Journal features a poll of 350 cannabis users, finding that 40% used cannabis to control their alcohol cravings, 66% as a replacement for prescription drugs and 26% for other, more potent, illegal drugs. http://www.physorg.com/news178868015.html Medicine & Health Tue, 01 Dec 2009 06:10:03 EST news178868015 Last year the UK government reclassified cannabis from a class C to a class B drug, partly out of concerns that cannabis, especially the more potent varieties, may increase the risk of schizophrenia in young people. But the evidence for the relationship between cannabis and schizophrenia or psychosis remains controversial. A new study has determined that it may be necessary to stop thousands of cannabis users in order to prevent a single case of schizophrenia. http://www.physorg.com/news175425054.html Medicine & Health Thu, 22 Oct 2009 10:11:58 EST news175425054 (PhysOrg.com) -- A new Lancet paper co-authored by a UQ researcher states that Australians are the highest cannabis users in the world, only matched by USA and New Zealand. http://www.physorg.com/news175252237.html Medicine & Health Tue, 20 Oct 2009 10:20:01 EST news175252237 Nearly four percent of adults around the world use cannabis, even though the drug raises many major health concerns, according to a paper published in The Lancet on Friday. http://www.physorg.com/news174892348.html Medicine & Health Fri, 16 Oct 2009 06:50:01 EST news174892348 In this week's PLoS Medicine, a team of researchers from Australia and the US, led by Louisa Degenhardt at the University of New South Wales, Sydney, makes the case for estimating the role that cannabis has worldwide as a risk factor for psychosis. http://www.physorg.com/news173420594.html Medicine & Health Tue, 29 Sep 2009 05:50:03 EST news173420594 In a first step toward engineering a drug-free Cannabis plant for hemp fiber and oil, University of Minnesota researchers have identified genes producing tetrahydrocannabinol (THC), the psychoactive substance in marijuana.

This has been shown by a study carried out by Valérie Daugé and her team at the Laboratory for Physiopathology of Diseases of the Central Nervous System (France) in the journal Neuropsychopharmacology. The findings could lead to therapeutic alternatives to existing substitution treatments. http://www.physorg.com/news166196260.html Medicine & Health Tue, 07 Jul 2009 14:38:02 EST news166196260 A new study published by University of Leicester researchers has found "convincing evidence" that cannabis smoke damages DNA in ways that could potentially increase the risk of cancer development in humans. http://www.physorg.com/news164348909.html Medicine & Health Tue, 16 Jun 2009 05:45:28 EST news164348909 When legal therapies let them down, some teens turn to cannabis. A new study, published in BioMed Central's open access journal Substance Abuse, Treatment, Prevention and Policy suggests that around a third of teens who smoke cannabis on a regular basis use it as a medication, rather than as a means of getting high. http://www.physorg.com/news159647774.html Medicine & Health Wed, 22 Apr 2009 19:36:49 EST news159647774 Patients with schizophrenia are able to correctly see through an illusion known as the 'hollow mask' illusion, probably because their brain disconnects 'what the eyes see' from what 'the brain thinks it is seeing', according to a joint UK and German study published in the journal NeuroImage. The findings shed light on why cannabis users may also be less deceived by the illusion whilst on the drug. http://www.physorg.com/news158233171.html Medicine & Health Mon, 06 Apr 2009 10:40:41 EST news158233171 Thrill-seeking young men are more likely to drive under the influence of cannabis (DUIC) and engage in reckless driving, according to a new Université de Montréal study.
