‘The worst case of scientific censorship since the Catholic Church banned the works of Galileo’: Scientists call for drugs to be legalised to allow proper study of their properties

 “The outlawing of drugs such as cannabis, MDMA and LSD amounts to the “the worst case of scientific censorship since the Catholic Church banned the works of Copernicus and Galileo”, the former Government drugs advisor Professor David Nutt has claimed.”

Professor Nutt, who was dismissed from the Home Office’s advisory council on drugs in 2009 after clashing with ministers, said that UN conventions on drugs in the 1960s and 1970s have delayed the development of “innovative treatments” for PTSD and depression by 30 years and also set back research into areas of neuroscience such as consciousness.

In a paper published today with two other scientists in the journal Nature Reviews Neuroscience, he said that drugs policy is being driven by “politics, not science”.

Professor Nutt left the Home Officer in 2009 after suggesting that taking MDMA ecstasy was no more dangerous than horse-riding and that alcohol and tobacco were more dangerous than many illegal drugs.

The possession of psychoactive drugs such cannabis, MDMA (ecstasy) and LSD for scientific purposes is stringently regulated in the UK and most other countries, in accordance with UN conventions that were agreed in response to the emergence of drug culture in the 1960s and 1970s.

Applying for a Government licence can be costly and time-consuming and many scientists are put off by a culture of “repression” surrounding drug science, Professor Nutt said.

“The laws scare off funders and most scientists are scared because they think if they break the law, they might get arrested,” he told The Independent. “I’m sure at some point someone’s going to arrest me. There is a sense of repression to the point that most people won’t do it.”

The paper, which is published to coincide with a conference on scientific research with psychedelics at Imperial College London, points to evidence that cannabis, MDMA and psychedelics such as LSD and psilocybin (the compound found in magic mushrooms) have unexplored medicinal benefits and argues that laws should be updated.

Small clinical studies of MDMA, which was originally used in the USA in the 1970s to improve communication in psychotherapy sessions, suggested that it could play a highly beneficial role in the treatment of PTSD patients. The paper’s authors said the drug could also help with “end of life anxiety” and couples therapy”.

Medical use of marijuana is already legal in 17 US states, and the drug has been shown to have benefits such as anxiety reduction and pain relief. However, Professor Nutt said that UK restrictions had blocked development of therapeutic applications for any of cannabis’ 16 active ingredients.

LSD, meanwhile, was widely researched in the 1950s and 1960s, with more than 1,000 papers investigating outcomes for more than 40,000 patients, with evidence suggesting that the drug might be an effective treatment for alcoholism, before bans on the drug around the world ended further research.”

Medical breakthroughs missed because of pointless drug bans

“In 1632 the Catholic Church convened a case against Galileo on the grounds that his work using the telescope to explore the nature of the heavens contradicted the church’s teaching – the culmination of a long fight that had lasted 16 years.

Galileo was put under house arrest and his research stopped. Some of his inquisitors refused even to look down a telescope, believing it to be the work of the devil. With his life under threat, Galileo retracted his claims that the earth moved around the sun and was not the centre of the universe. A ban by the papal Congregation of the Index on all books advocating the Copernican system of planetary motion – which we use today – was not revoked until 1758.

Three centuries later we have an equivalent case of scientific censorship. In the 1960s and the 1970s the UN effectively banned a whole range of drugs from cannabis, opioids and cocaine through to psychedelics – LSD and “magic mushrooms”. They did this in a futile attempt to reduce the use and harms of these drugs, but both consumption and harms have increased ten-fold since then, and many of the negative effects of these laws include the rise of AIDS and the collapse of law and order in Mexico.

However, another major impact of these laws – restriction of research – has hardly been discussed. Yet this is arguably as significant a problem and must change.

A research black hole

Two of the most limiting areas have been in the fields of research into cannabis and psychedelics, both of which were put into the UN’s most restrictive lists, deemed to have no value to medicine.

Currently in the UK to work with these compounds you need a special licence, which along with additional police checks, costs more than £5000 and takes a year to get. In the UK only three hospitals have these, making clinical research almost impossible. Contrast this with the situation for heroin, a much more abused and harmful drug, which can be held by any hospital with a license.

The field of research that has been most censored is that of psychedelics (LSD and psilocybin) and empathogens (MDMA and Ecstasy).

Before the LSD ban there were more than 1000 publications on its therapeutic potential – its hallucinogenic properties undiscovered until five years after its discovery in 1938. Since then there have been none – despite its proven utility in disorders including alcoholism, end of life suffering and cancer pain.

The ban was largely driven by political concerns. Despite being justified by claims of harm such as people dying while trying to fly, its use was also discouraging young people in the US fighting in the Vietnam war.

The psychedelic state is also one of the most intriguing kinds of brain function that can illuminate the fundamental mechanisms of the brain and give us novel insights into consciousness.

Drugs such as MDMA can help conditions such as post traumatic stress disorder.

The banning of cannabis was purely political. It was already being used as a medicine in many countries before it was banned. With the notable exception of The Netherlands, most countries agreed to this dishonest change in status. In the UK, it has criminalised many patients with incurable conditions such as multiple sclerosis who could benefit from the drug.

But it has also led to a severe impairment of medical research into the cannabis plant. There are more than 50 active chemicals in the cannabis plant and many of these were discovered in the UK. However, turning any of these into medicines is very slow due to unnecessarily tough regulations. This has set back UK leadership in the field and wasted huge economic opportunities.

Basic neuroscience research has also been held back. Cannabis works on cannabinoid receptors in the brain – and we have a lot of these – surprisingly more than our dopamine (pleasure and reward) and serotonin receptors (wellbeing and happiness) combined. Cannabinoid receptors do many things and are involved in learning and memory, eating and sleep anxiety.

Their role is therefore of great interest but studying them requires working with compounds such as THC (the element of cannabis that makes people stoned). But again, the regulations make getting these expensive and difficult.

Time to challenge outdated controls

What can be done? It’s very easy once we accept that no meaningful benefits come from controls that have been left unchallenged for 50 years. In the UK we can exempt hospitals from the need to have the licences – they could hold cannabis safely alongside heroin. We can also exempt very small amounts of the drugs (below a clinically meaningful dose for example) from any control at all, so that scientists doing basic research can work without hindrance.

The transfer of small amounts of test compounds between different countries should also be exempt from import and export rules that now apply to every compound on a case-by-case basis – which also significantly impairs detection of new “legal highs” because samples can’t easily be shared across Europe.

Ideally, a fundamental change in the world perspective should also happen. The UN conventions are outmoded and should be fully revised. This can happen at the 2016 UN General Assembly Special Session (UNGASS) meeting into drug control – the first opportunity to do so in some time.

In the meantime, let’s get scientists as well as patient and civil liberty groups working together to achieve this. We need more petitions. We need more leadership. Some countries are already showing this. New Zealand is beginning to change where it stands on legal highs with the Psychoactive Substances Bill. Some South American countries are also now taking a more rational approach. What we need to do now is put science at the forefront of research.”

Psychoactive cannabinoids reduce gastrointestinal propulsion and motility in rodents.

“Marijuana has been reported to be an effective antinauseant and antiemetic in patients receiving cancer chemotherapy.

Whether this is due to psychological changes, central antiemetic properties and/or direct effects on gastrointestinal (GI) function is not known. The purpose of these investigations was to determine whether the major constituents of marijuana and the synthetic cannabinoid nabilone have any effects on GI function which can be detected in rodent models of GI transit and motility. Intravenous delta 9-tetrahydrocannabinol (delta 9-THC) slowed the rate of gastric emptying and small intestinal transit in mice and in rats. Delta 9,11-THC, cannabinol and nabilone given i.v. also inhibited small intestinal transit in mice, but were less effective in reducing gastric emptying. Cannabidiol given i.v. had no effect on gastric emptying or intestinal transit. Those cannabinoids which inhibited GI transit did so at doses equal to, or lower, than those reported to produce central nervous system activity. In rats, delta 9-THC produced greater inhibition of gastric emptying and small intestinal transit than large bowel transit, indicating a selectivity for the more proximal sections of the gut. In addition, i.v. delta 9-THC decreased the frequency of both gastric and intestinal contractions without altering intraluminal pressure. Such changes probably reflect a decrease in propulsive activity, without change in basal tone.

These data indicate that delta 9-THC, delta 9,11-THC, cannabinol and nabilone (but not cannabidiol) exert an inhibitory effect on GI transit and motility in rats.”

Pharmacological synergism between cannabinoids and paclitaxel in gastric cancer cell lines.

“Orally applicable Delta9-tetrahydrocannabinol and its synthetic derivatives have been used as antiemetic drugs during chemotherapy in cancer patients.

 However, it is not well known how cannabinoids influence the effects of chemotherapeutic agents on malignant tumors. In this study, we investigated how the endogenous cannabinoid anandamide (AEA) changes the effect of paclitaxel on gastric cancer cell lines.

 In the human gastric cancer cell line, HGC-27, which express cannabinoid receptor 1 (CB1), AEA stimulated proliferation at concentrations under 1 microM, while it strongly suppressed proliferation through the induction of apoptosis at 10 microM. This bimodal effect was reproduced by a selective CB1 agonist, arachidonyl-2-chloroethylamide, although the effects were less marked. When AEA was used with paclitaxel, AEA at 10 microM synergistically enhanced the cytotoxic effect of paclitaxel, whereas it showed no significant effect at lower concentrations. Flow cytometric analysis revealed that addition of 10 microM AEA synergistically enhanced paclitaxel-induced apoptosis, possibly through the activation of caspase-3, -8, and -9.

Our results suggest that cannabinoids could be a good palliative agent for cancer patients receiving paclitaxel.”

Effect of a synthetic cannabinoid agonist on the proliferation and invasion of gastric cancer cells.

“Although cannabinoids are associated with antineoplastic activity in a number of cancer cell types, the effect in gastric cancer cells has not been clarified. In the present study, we investigated the effects of a cannabinoid agonist on gastric cancer cell proliferation and invasion.

The cannabinoid agonist WIN 55,212-2 inhibited the proliferation of human gastric cancer cells in a dose-dependent manner and that this effect was mediated partially by the CB(1) receptor. We also found that WIN 55,212-2 induced apoptosis and down-regulation of the phospho-AKT expression in human gastric cancer cells. Furthermore, WIN 55,212-2 treatment inhibited the invasion of gastric cancer cells, and down-regulated the expression of MMP-2 and VEGF-A through the cannabinoid receptors.

Our results open the possibilities in using cannabinoids as a new gastric cancer therapy.”

Antiproliferative mechanism of a cannabinoid agonist by cell cycle arrest in human gastric cancer cells.

“For gastric cancers, the antineoplastic activity of cannabinoids has been investigated in only a few reports and knowledge regarding the mechanisms involved is limited. We have reported previously that treatment of gastric cancer cells with a cannabinoid agonist significantly decreased cell proliferation and induced apoptosis.

Here, we evaluated the effects of cannabinoids on various cellular mediators involved in cell cycle arrest in gastric cancer cells. AGS and MKN-1 cell lines were used as human gastric cancer cells and WIN 55,212-2 as a cannabinoid agonist.

 …Cell cycle arrest preceded apoptotic response. Thus, this cannabinoid agonist can reduce gastric cancer cell proliferation via G1 phase cell cycle arrest, which is mediated via activation of the MAPK pathway and inhibition of pAKT.”

Even More Science Suggesting That Cannabinoids May Halt Diabetes

“Preclinical study data published online in the scientific journal Nutrition & Diabetes reports that tetrahydrocannabivarin (THCV) — a naturally occurring analogue of THC — possesses positive metabolic effects in animal models of obesity.

British researchers assessed the effects of THCV administration on dietary-induced and genetically modified obese mice. Authors reported that although THCV administration did not significantly affect food intake or body weight gain in any of the models, it did produce several metabolically beneficial effects, including reduced glucose intolerance, improved glucose tolerance, improved liver triglyceride levels, and increased insulin sensitivity.

Researchers concluded: “Based on these data, it can be suggested that THCV may be useful for the treatment of the metabolic syndrome and/or type 2 diabetes (adult onset diabetes), either alone or in combination with existing treatments. Given the reported benefits of another non-THC cannabinoid, CBD in type 1 diabetes, a CBD/THCV combination may be beneficial for different types of diabetes mellitus.””

Looking at Cannabis Based Type 2 Treatment

“One of the classic effects of cannabis on people is raging hunger-the “marijuana munchies.” The drug has been used to good effect on people with diseases that diminish appetite, helping them to regain a healthy interest in food. So it is a bit ironic that British drug maker GW Pharmaceuticals has created a cross-bred cannabis plant whose appetite-suppressing qualities could be used to treat type 2 diabetes.”

 
“The new strain contains an appetite-suppressing compound called THCV (tetrahydrocannabivarin), a cannabinoid* found in cannabis sativa-marijuana. The company sees a drug that uses THCV as potentially useful in helping type 2s and obese people control their appetites-a key to good blood sugar control.

In 2010, GW introduced a cannabis-based drug to treat the symptoms of multiple sclerosis. Already, the company has found 60 cannabinoids in the cannabis sativa plant. A company spokesman says that only 12 to 15 of them have been explored in any depth.

*Cannabinoids are the active ingredients in cannabis sativa that create the plant’s physical and mental effects when it is ingested or smoked.”

Marijuana and its receptor protein in brain control epilepsy

“VCU study is first to test anticonvulsant potential of marijuana and brain recurrent seizures. 

Ingredients in marijuana and the cannabinoid receptor protein produced naturally in the body to regulate the central nervous system and other bodily functions play a critical role in controlling spontaneous seizures in epilepsy, according to a new study by researchers at Virginia Commonwealth University.

The study, the first to look at marijuana and the brain’s cannabinoid system in live animals with spontaneous, recurrent seizures, suggests new avenues that researchers can explore in their search for more-effective drugs to treat epileptic patients who don’t respond to today’s anticonvulsant medications or surgery.

The results appear in the Oct. 1 issue of the Journal of Pharmacology and Experimental Therapeutics.

“Although marijuana is illegal in the United States, individuals both here and abroad report that marijuana has been therapeutic for them in the treatment of a variety of ailments, including epilepsy,” says Dr. Robert J. DeLorenzo, professor of neurology in the VCU School of Medicine.

 “If we can understand how marijuana works to end seizures, we may be able to develop novel drugs that might do a better job of treating epileptic seizures.” 

Epilepsy is one of the most common neurological conditions, characterized by spontaneously recurrent seizures. Approximately 1 percent of Americans have epilepsy, and 30 percent of those patients are resistant to conventional anticonvulsant drug treatments.

Cannabinoids have been used as a natural remedy for seizures for thousands of years, and studies since at least 1974 have found that the primary psychoactive compound in marijuana displays anticonvulsant properties.”

New Study: Cannabinoids Protect the Brain and Heart From Injury

“Cannabis is in the news again for its purported medicinal benefits, with researchers in Israel last week indicating it may help prevent trauma to the brain in certain circumstances and may also help with cardiac problems. A few months ago an English pharmaceutical company that manufactures cannabinoids announced it was developing a new treatment for epilepsy using them.”

Los Angeles City Council Votes To Ban Medical Marijuana Dispensaries

“Prof. Yosef Sarne in the Adelson Center for the Biology of Addictive Diseases in the Department of Physiology and Pharmacology at Tel Aviv University says that cannabis has neuro-protective qualities. He has found that extremely low doses of tetrahydrocannabinol or THC- the psychoactive component of marijuana- can protect the brain from long-term cognitive damage in the wake of injury from hypoxia (lack of oxygen), seizures, or toxic drugs.”
