The World Lung Foundation and the American Cancer Society have compiled in The Tobacco Atlas a damning list of morbidity and mortality inflicted by cigarettes on the world’s people. Cigarettes are powerful drugs, the most addicting and lethal of all drugs. Cigarettes kill far more people than all the illegal drugs combined. In the USA, at least 30 times as many people die from cigarettes than all illicit drugs.

The lists of damage from cigarettes to the health of the world’s people is lengthy:
- Smoking cigarettes contributes to 6 of the 8 leading causes of death.
- “Tobacco accounts for one out of every 10 deaths worldwide”
- Cigarette smoking killed 100 million people during the last century; it may kill one billion during this century.
- Tobacco kills one-third to one-half of those who smoke it. Smokers die, on the average, about 15 years before people who don’t smoke. Chewed tobacco is also often deadly dangerous.
The most popular illicit drug, cannabis, kills zero people. Marijuana does not have a lethal dose and is not associated with morbidity. Actually though, a few people are killed by association with cannabis, usually in SWAT raids. In Malaysia, about one person is hanged each month for cannabis possession. Cannabis smoke, like all smoke, does contain some toxins, but has not been shown to cause cancer. Elements specific to marijuana smoke, especially THC, may be providing protection against tumors. Medical cannabis is now commonly consumed via vaporizer, so all toxins are eliminated.
What if swine flu developed into great plague next year and death swept across the globe leaving behind six million corpses? The world’s people would tremble in fear. We would grimace in mourning and horror among the mountains of the dead. Yet when this mass death is delivered by the artificial plague of cigarettes, the terrible toll is dismissed with a shrug.
Instead, a world-wide crusade is underway, lead by the USA, with the goal of stamping out not cigarettes, but instead the other drugs. Although they cause are the cause one one death for every 30 from cigarettes (in the USA) these other drugs, such as cocaine and heroin, even nearly harmless drugs such as cannabis, are labeled poisons. Those possessing them, at least in the USA and places like Malaysia, are treated with penalties harsher than for real criminals with actual victims.
In light of cigarettes deadly toll, should the USA and other countries prohibit cigarettes and add them to the list of illicit drugs, where they clearly belong? Clearly NOT. The prohibition approach has failed spectacularly, as it did alcohol prohibition in the USA of the 1920s. The difference is that with alcohol the mistake was realized. With the war on drugs, into its 5th decade and with the USA quintupling its prison population into the world’s largest, the prohibitionist, hard-line, lock-em-up stance continues with almost no critical examination.
This ineffective and wasteful prohibition/incarceration model has caused immense collateral damage to American society. As has worked so well in Portugal, drugs should be removed from the law enforcement, zero-tolerance model into a harm reduction approach.
Such an approach has actually worked very well for cigarettes in the USA over the last 20 years. With education, segregation of smoking and higher taxes on cigarettes to help pay for their health toll, smoking has lost much of its popularity. Cigarette consumption has markedly declined in the USA with no arrests or violations of civil liberties.

The coroner’s report showed that Michael Jackson, in his overpowering desire to sleep, demanded and received narcotics so powerful they were, obviously, life-threatening. Inability to sleep can be profoundly disturbing. Sleep deprivation is a key CIA torture technique. “It causes people to feel absolutely crazy.” Insomnia in the elderly is a major cause of depression and lack of will to live. Jackson’s insomnia appears profound; he received injections of powerfeul drugs from 2am until 10am.
Insomnia is one of the conditions legally treatable with medical cannabis in some states. Prohibitionist lampoon such applications for medical marijuana as trivial. Actually, the effectiveness of cannabis for treating insomia points to how the plant provides nearly a universal medication. What percentage of the population sometimes has trouble sleeping? If seeking medication for the problem, why should they be forced into drugs stronger than cannabis, those with real dangers, including addiction and death? Likewise should those suffering pain be forced into medications less safe than cannabis by drug laws formed in ignorance and prejudice?
Strangely, it is a misplaced sense of morality that seems to motivate prohibitionists. Those wishing to restrict the use of medical cannabis on moral grounds should realized that Queen Victoria herself made use of medical cannabis for menstrual cramps. Mitch Earlywine in Understanding Marijuana: A New Look at the Scientic Evidence, on page 113 mentions that the Queen’s chief physician, Dr. J. R. Reynolds, “recommended the drug for insomnia.” Reynolds wrote of the therapeutic effects of the drug in Lancet in 1890. So, despite the restrictions Victorian morality, the Queen and her subjects enjoyed medical freedoms deemed illegal in the USA over a century later.
Apparently the cannabinoid best suited for aided sleep is CBD, cannabidiol. High CBD cannabis medications in the form of edibles and tinctures are available in dispensaries not far from Michael Jackson’s LA home. What a shame the entertainer and his doctor focused on high-risk narcotics instead of the far safer cannabis medications available nearby. As DEA law judge Francis Young noted back in 1988, “Marijuana, in its natural form, is one of the safest therapeutically active substances known to man. By any measure of rational analysis marijuana can be safely used within a supervised routine of medical care.”

Those interested in medical cannabis will remember that the CB1 receptors, discovered less than 20 years ago, are activated by THC and other cannabinoids in cannabis. This activation provides the psychoactive effects of cannabis and also some of its other health enhancing properties. CB receptors also respond to endocannabinoids produced by own bodies, primarily in our nerve cells. The receptors are part of the endocannabinoid receptor (or regulatory) system, now seen as a major physiological system, with important roles in pain relief, neuroprotection and anti-inflammation, even digestion and vision.
Such CB1 activation by THC from the plant world or anandamide from our own cells, along with other cannabinoids produced by the cannabis plant or our own bodies, can provide profound health benefits. Cannabinoids also work by activating CB2 receptors (primarily found on immune cells). Independent of their actions on receptors, cannabinoids are anti-oxidants, protecting nerve cells and other tissue from oxidation stress.
In the photo below, the CB1 receptors are being marked by the inverse agonist, 18F]MK-9470, a positron emission tomography (PET) tracer for in vivo human PET brain imaging of the cannabinoid-1 receptor. Inverse agonists tend to cause receptors to respond in ways opposite their response to agonists such as THC and anandamide. In the case of cannabinoid receptors, hope that inverse agonists might serve as obesity control agents has faded with problems from nausea and mood disturbances.

The physics of what goes on during such as PET scan it astounding. The process would appear to be highly hazardous to health, yet the procedure is commonplace and apparently without risk. Markers with affinities for certain cell types, such as the compounds used above, MK-9470, emit anti-matter. A positron is the anti-matter equivalent of an electron. When it is emitted from the source, in this case on a CB1 receptor in the brain, it travels only a short distance, a millimeter or so, before encountering its matter equivalent, an electron.
When matter electron and antimatter positron meet, the result is annihilation. Such an encounter releases a short burst of highly energetic photons in the form of gamma rays. Why matter/antimatter annihilation with accompanying gamma ray burst inside the brain is not fatal is not exactly clear. Perhaps a high-energy physicist could comment. Or even a low-energy physicist after coffee.
During this positron emission tomography, sensors detect where the gamma rays are coming from and map these in a 3D representation of brain anatomy and activity. In the images above the patterns of gamma rays being emitted from this matter/antimatter annihilation show the relative distributions of CB1 receptors in various parts of the human brain. See the original research for more detail. Although they are most highly concentrated in the brain, CB1 receptors are also found throughout the entire human body, mainly on nerve cell membranes.
