Okay, let me say right up front that a) I know that headline is provocative, and b) neither I nor anyone can answer the question with any certainty given what we know and don't know so far about Michael Jackson's death. But the question needs to be asked.

It needs to be asked because suspicions that prescription painkillers may have been involved in Jackson's death are strong enough that the federal Drug Enforcement Administration has been brought into the investigation. And we know that he had a documented history of battling pain and at least some acknowledged problems with prescription painkillers.

We don't know yet what pain drugs Jackson was on or what they were prescribed for. But if he was addicted to prescription painkillers, that addiction almost certainly started with legitimate and needed treatment for real pain. And that's where medical marijuana might have helped.

We know -- repeat, we know -- that marijuana can be effective against certain types of pain. As The Lancet Neurology put it a few years ago, "cannabinoids inhibit pain in virtually every experimental pain paradigm." We know that human clinical trials such as this one have found marijuana to be effective, particularly for neuropathic pain.

And there is considerable evidence that marijuana and cannabinoids can act synergistically with opioid painkillers, providing better pain relief at lower doses than either class of drugs by itself. For example animal studies such as this one have reported that such combination therapy avoids the development of tolerance and allows effective relief with lowered opioid doses -- avoiding the pattern of escalating doses that can lead to addiction and overdose risk.

And there is evidence that this same effect occurs in people. For example, in a series of cases reported in the Journal of Pain and Symptom Management (which, alas, you can only access by paying for it -- sorry!), patients on morphine and other narcotics were able to cut their doses roughly in half when smoked marijuana was added to their regimen.

At MPP, we hear similar stories from patients all the time: Again and again, patients tell us that use of medical marijuana allows them to cut back or eliminate the heavy doses of narcotic painkillers they'd been taking, while obtaining equal or better relief. There is enough science corroborating these accounts that they deserve to be taken seriously.

We can't yet say that medical marijuana could have saved Michael Jackson, and we may never know that for sure. But there is simply no reasonable doubt that marijuana can help some chronic pain patients reduce both their suffering and their consumption of addictive and potentially deadly narcotics. If the U.S. government acknowledged that reality instead of denying it, lives could be saved -- maybe lots of them.

An FDA panel just recommended reducing the maximum dose of acetaminophen, the active ingredient in Tylenol. Taken by millions of Americans every day as either a stand-alone medication or as an ingredient in various over-the-counter cold remedies, acetaminophen is the leading cause of liver failure in the U.S., resulting in hundreds of deaths by overdose every year.

And they say marijuana is too dangerous to be medicine?

MPP's Assistant Director of Communications is interviewed by WUSA-TV 9 in Washington, DC, about the removal of a legal provision that prevented the District of Columbia from enacting any marijuana reform legislation. Also discussed was the case of Jonathan Magbie, a medical marijuana patient who died in the DC jail due to lack of medical treatment while serving a sentence for marijuana possession. 06/29/2009

Steve Fox, MPP’s new director of state campaigns (who was also MPP’s federal lobbyist from 2002-2005), sends in the following dispatch:

While riding the Metro’s Red Line yesterday, I spotted former drug czar John Walters entering the train. When he ended up standing right beside me, I realized I couldn’t pass up the chance for a conversation. I know it sounds like a fruitless endeavor, but I’m an eternal optimist and thought, “Maybe if we have a casual lunch together, he’ll come to see the folly of keeping marijuana illegal.”

I opened with a polite, “Hello, Mr. Walters. I just wanted to introduce myself. I am Steve Fox and I work with the Marijuana Policy Project.” The chipper look on his face quickly changed. It looked like he had just thrown up in his mouth a little and was regretting the fact that he had nowhere to spit.

I said, “I know we have been on opposite sides of the issue, but I was wondering whether you would be interested in having lunch any time just to talk about our differences and to see whether we have any mutual interests.” He seemed to stifle a laugh and said, “I don’t think that would be worth our time. You know where I stand and I know where you stand.” This is not the first time I have been turned down for a date, so I let it slide right off. More importantly, I had more work to do. I had just eight more minutes to get him to support ending marijuana prohibition.

I don’t mean to spoil the ending, but it didn’t work. But it was a fascinating conversation nonetheless. The most interesting part is that he never broke character. I assumed he must, at some level, appreciate that most of what he said during his tenure as drug czar was either a distortion of the facts or completely ignorant of other available information. Boy, was I wrong.

He proceeded to give me all of his standard lines as if they were actually true and meaningful, like alleging (incorrectly) that marijuana is the leading cause of drug treatment admissions for teens, even more than alcohol.

When I asked him if he really thinks that marijuana is more harmful than alcohol, he quickly said, “Sure.” I said, “I mean, in terms of overdose deaths, overall deaths from use, the likelihood of causing domestic abuse and other forms of violence?” He said, “I talk to directors of treatment facilities and they tell me that those who are violent use all kinds of substances – marijuana, alcohol, heroin, cocaine…”

As we reached his stop, I repeated my lunch offer and extended my hand with my business card. For a moment, I thought he was going to just walk away, but he took it with a look of annoyance on his face.

I assume that card is in the trash somewhere now. But perhaps it is sitting on his desk and each look at it is making him ponder the true value of his work as drug czar.

As I said, I am an optimist.

[P.S. – Be sure to check out Steve’s new book, Marijuana is Safer: So Why Are We Driving People to Drink? (Chelsea Green, July 2009).]

From time to time we get some flack for pointing out that as a "recreational" substance, marijuana is safer than alcohol. Anyone who doubts that claim might want to look at this new study from The Lancet, one of the world's top medical journals.

Researchers reviewed information on deaths in three major Russian cities from 1990 to 2001 and questioned family members about the decedents' alcohol use, reporting the astonishing finding that "in several recent years, alcohol was a cause of more than half of all Russian deaths at ages 15-54 years." Causes of death that were greatly increased by heavy alcohol use included accidents, violence, alcohol poisoning, and several types of cancer.

We've said it before, but we'll keep saying it: No drug is 100% harmless, but marijuana simply does not cause anything near the wreckage that alcohol causes, even in very heavy users.

MPP's Neal Levine talks with Dana Gentry about the increasing support for taxing and regulating marijuana like alcohol and the rewards of such a system. He also discusses the plans for a ballot initiative to be voted on in 2012. Mr. Levine is the Director of the Marijuana Policy Project of Nevada. 06/11/2009

Today the New Hampshire Legislature approved a medical marijuana bill custom tailored to addresses the governor's concerns in hopes of avoiding a veto that would leave the state’s medical marijuana patients vulnerable to arrest, even if they have their doctor’s recommendation.

Gov. John Lynch told lawmakers that he would veto the bill in its original form, which passed both chambers last month, if eight specific concerns of his were not addressed.

A special legislative committee spent the past month revising the bill according to those eight concerns, which you can view here, along with how the revised bill that the Legislature passed today addresses them.

The question now is whether the governor was sincere about finding a workable compromise that meets the needs of medical marijuana patients. In the next couple weeks, we’ll be reminding the governor of the seriously ill who are depending on him to do the right thing by purchasing radio and TV ad time highlighting the patients whose lives hang in the balance.

If you're a New Hampshire resident, you can let Gov. Lynch know it's time for him to allow this much-needed reform and stop the prosecution of patients for simply trying to relieve their pain with a proven safe, effective medicine.

From time to time drug warriors tell us that no one goes to jail for marijuana possession. Tell that to Cynthia Prude, whose daughter Theresa died in a Houston, Texas jail over the weekend while serving a two and one-half week jail sentence for marijuana possession.

Thus far, officials aren't revealing the circumstances or the cause of death, but this isn't the first time someone has died serving a short jail sentence for marijuana possession. In September 2004, quadriplegic Jonathan Magbie -- who used marijuana to relieve the chronic pain lingering from the childhood accident that left him paralyzed -- died in the Washington, D.C., jail while serving a 10-day sentence for marijuana possession.

Here in the U.S., medical marijuana is still routinely branded as some sort of sinister "drug legalizer" conspiracy. In Israel, according to a fascinating article in the newspaper Haaretz, the leading conspirator appears to be the Ministry of Health.

Officials have authorized over 700 patients to use marijuana for medical purposes, and expect the number to rise to 1,200 within three months. Authorities are in the process of authorizing five or six producers to handle the needs of this growing patient population. Dr. Yehuda Baruch, who oversees the program, says the average prescription is for 100 grams -- a little over three ounces -- per month. So much for the claims of U.S. prohibitionists that allowing patients even an ounce or two would flood their communities with marijuana.

And doctors are finding marijuana amazingly useful. Haaretz reports:

When Cannabis was approved for medicinal purposes in 1999, it was originally intended for terminal cancer and AIDS patients. Today it is being used in earlier stages of illness and for a wider array of diseases, including Parkinson's, Tourette Syndrome, Multiple Sclerosis, chronic pain and shell shock. The medical establishment is also increasingly recognizing Cannabis' effectiveness in treating illness.

At the Hadassah Ein Kerem hospital's Bone Marrow Transplantation department, patients including children and babies are treated using drops of oil derived from Cannabis. "It has no side effects and is largely effective in treating patients," said department chief, Professor Reuven Or. "I would say it is effective in 80 percent of patients, which is a lot."

Professor Or continued, "It stimulates the appetite and minimizes nausea and vomiting, which is of great importance in Oncology. It also has anti-inflammatory properties, which helps in cases of infection or inflammation caused by radiation. Along with this, Cannabis eases the coping process for patients - it improves their morale and lowers depression, and these are important parameters for patients battling disease."

One year after a SWAT team shot and killed two Labrador retrievers in a marijuana raid on an innocent small-town mayor's family, the Prince George's County, Md., sheriff responsible has announced his department did nothing wrong.

Here's The Washington Post's summary of the incident that occurred last July:

Members of the SWAT team killed [Cheye] Calvo's black Labrador retrievers after deputies broke down his door and raided his home in search of a drug-filled package that had been addressed to Calvo's wife.

Law enforcement officials have since acknowledged that Calvo and his wife, Trinity Tomsic, were victims of a smuggling scheme that used a FedEx driver to ship drugs. They said the couple knew nothing about the box. County police, who were leading the drug investigation, have said they were unaware it was the mayor's house.

Some drug investigation. PG County cops failed to even Google Calvo to determine whom they might be dealing with. They also neglected to coordinate with the sheriff in Berwyn Heights, the small D.C. suburb where Calvo served as mayor, who said he could have cleared this up with a simple visit to Calvo's home.

Yet PG County Sheriff Michael Jackson insists his investigation proves "what I've felt all along: My deputies did their job to the fullest extent of their abilities."

Actually, maybe Jackson's right. I've made this point before, but if his deputies did their jobs the best they could, then maybe it's time to change the policies that shape their jobs.
