The inhalation of one marijuana cigarette per day over a 20-year period is not associated with adverse changes in lung health, according to data published online ahead of print in the journal Annals of the American Thoracic Society.
Investigators at Emory University in Atlanta assessed marijuana smoke exposure and lung health in a large representative sample of US adults age 18 to 59. Researchers reported that cannabis exposure was not associated with FEV1 (forced expiratory volume) decline or deleterious change in spirometric values of small airways disease.
Authors further reported that marijuana smoke exposure may even be associated with some protective lung effects among long-term smokers of tobacco. Investigators acknowledged, “[T]he pattern of marijuana’s effects seems to be distinctly different when compared to that of tobacco use.”
Researchers also acknowledged that habitual cannabis consumers were more likely to self-report increased symptoms of bronchitis, a finding that is consistent with previous literature. Separate studies indicate that subjects who vaporize cannabis report fewer adverse respiratory symptoms than do those who inhale combustive marijuana smoke.
Authors concluded, “[I]n a large representative sample of US adults, ongoing use of marijuana is associated with increased respiratory symptoms of bronchitis without a significant functional abnormality in spirometry, and cumulative marijuana use under 20 joint-years is not associated with significant effects on lung function.”
This study is the largest cross-sectional analysis to date examining the relationship between marijuana use and spirometric parameters of lung health.
A separate study published in 2012 in The Journal of the American Medical Association (JAMA) similarly reported that cumulative marijuana smoke exposure over a period of up to 7 joint-years (the equivalent of up to one marijuana cigarette per day for seven years) was not associated with adverse effects on pulmonary function.
A 2013 review also published in the Annals of the American Thoracic Society acknowledged that marijuana smoke exposure was not positively associated with the development of lung cancer, chronic obstructive pulmonary disease (COPD), emphysema, or bullous lung disease. It concluded: “[H]abitual use of marijuana alone does not appear to lead to significant abnormalities in lung function. Findings from a limited number of well-designed epidemiological studies do not suggest an increased risk of either lung or upper airway cancer from light or moderate use. … Overall, the risks of pulmonary complications of regular use of marijuana appear to be relatively small and far lower than those of tobacco smoking.”

#1 Marijuana Legalization Measures Win Big On Election Day
Voters in Oregon and Alaska decided on Election Day in favor of statewide initiatives legalizing the commercial production and sale of marijuana for adults, while voters in the nation’s capitol and in numerous other cities nationwide similarly decided on local measures to eliminate marijuana possession penalties.
#2 Colorado And Washington Begin Regulating Retail Marijuana Sales
Two states, Colorado and Washington, initiated retail marijuana sales in 2014. Colorado’s program began on January 1. In Washington, state-licensed retail outlets began legally selling cannabis to adults in July.
#3 Congress Enacts Measure Protecting State-Sponsored Medi-Pot Programs
President Barack Obama signed spending legislation into law in December that included a provision limiting the Justice Department’s ability to take criminal action against state-licensed individuals or operations that are acting in full compliance with the medical marijuana laws of their states. The amendment states, “None of the funds made available in this act to the Department of Justice may be used … to prevent … states … from implementing their own state laws that authorize the use, distribution, possession, or cultivation of medical marijuana.”
#4 Congress Moves To Permit State-Sanctioned Hemp Cultivation
Federal lawmakers approved legislation in February permitting state-sponsored hemp cultivation to move forward despite the plant’s federal status as a Schedule I prohibited substance.
#5 Federal Judge Hears Challenge To Cannabis’ Schedule I Status
United States District Judge Kimberly Mueller heard five days of testimony in October in regard to the constitutionality of marijuana’s Schedule I status under federal law. Defense counsel and their experts argued that the scientific literature is not supportive of the plant’s present categorization. Judge Mueller is expected to make her ruling in early 2015.
#6 JAMA: Fewer Opiate-Related Deaths In Medical Marijuana States
The enactment of statewide medicinal marijuana laws is associated with significantly lower state-level opioid overdose mortality rates, according to data published in August in JAMA Internal Medicine. Researchers reported, “States with medical cannabis laws had a 24.8 percent lower mean annual opioid overdose mortality rate compared with states without medical cannabis laws.”
#7 President Acknowledges That Booze Is More Harmful Than Marijuana
Consuming cannabis is less harmful to the individual than is drinking alcohol, President Barack Obama acknowledged in January in an interview with The New Yorker. “I don’t think it (marijuana) is more dangerous than alcohol,” he stated. He added, [W]e should not be locking up kids or individual users for long stretches of jail time.”
#8 Study: Medical Marijuana States Have Fewer Violent Crimes
Medicinal cannabis laws are not associated with any rise in statewide criminal activity, according to data published in April in the journal PLoS ONE. “Medical marijuana laws were not found to have a crime exacerbating effect on any of the seven crime types. On the contrary, our findings indicated that MML precedes a reduction in homicide and assault,” authors concluded. “In sum, these findings run counter to arguments suggesting the legalization of marijuana for medical purposes poses a danger to public health in terms of exposure to violent crime and property crimes.”
#9 NYT Editors Opine In Favor Of Legalizing Cannabis
The New York Times editorial board in July called upon federal lawmakers to end the criminalization of cannabis for those over the age of 21. The paper’s editors opined: “The federal government should repeal the ban on marijuana. … Moderate use of marijuana does not appear to pose a risk for otherwise healthy adults. … [W]e believe that on every level, … the balance falls squarely on the side of national legalization.”
#10 Americans Say Marijuana Is Less Harmful To Health Than Sugar
Americans believe that consuming cannabis poses less harm to health than does the consumption of tobacco, alcohol, or sugar, according to the findings of a Wall Street Journal/NBC News poll released in March. Respondents were asked which of the four substances they believed to be “most harmful to a person’s overall health.” Most respondents said tobacco (49 percent), followed by alcohol (24 percent) and sugar (15 percent).
Six out of ten voters believe that states, not the federal government, should authorize and enforce marijuana policy, according to national polling data reported this week by the Washington, DC think-tank Third Way.
When presented with the option, 60 percent of respondents said that state officials ought to possess the authority to “control and decide whether to legalize marijuana.” Only 34 percent of those polled said that the federal government ought to enforce marijuana laws.
Similarly, a super-majority of voters (67 percent) agreed, “Congress should pass a bill giving states that have legalized marijuana a safe haven from federal marijuana laws, so long as they have a strong regulatory system.”
Overall, 50 percent of voters said that they support legalizing marijuana for recreational purposes while 47 percent opposed the notion. However, among those opposed to legalization, 21 percent endorsed the idea of Congress providing a “safe haven” from federal prohibition in those states that have chosen to legalize the plant’s use and sale.
“The fact that state legalization of marijuana violates federal law and creates an untenable policy situation was clear – and the voters we polled responded not with ideological proclamations but by supporting a middle-ground, pragmatic policy which would ease that conflict as the legal landscape continues to quickly shift,” representatives for the think-tank stated in a media release. “This means marijuana is not an issue of absolutes for many Americans – rather, it requires a nuanced balancing of values and interests.”
Nationwide, voter support for cannabis legalization was highest among Democrats (64 percent), Millennials (61 percent), and non-white/Hispanic voters (61 percent). A majority of women voters and self-identified Republicans opposed legalizing marijuana for recreational purposes. By contrast, majority support (78 percent) for the legalization of cannabis for medicinal purposes extended throughout all demographics.
Among respondents, 54 percent expressed a favorable view of those who used cannabis therapeutically, while only 36 percent said that they possessed a favorable view of social consumers.
When it came to the issue of how to most effectively influence voters’ opinions on marijuana law reform, authors reported that neither negative nor positive messaging “moved voters substantially in either direction.” Specifically, authors’ reported that many respondents failed to sympathize with the idea that the drug war was overly punitive or that the federal government might once again begin cracking down on state-compliant cannabis consumers and providers.
Authors concluded, “As opponents lean heavily into values-based arguments regarding teenage marijuana use and highway safety, more research still needs to be done to identify a compelling value for legalizing recreational marijuana – the way that compassion underlies support for medical marijuana.”
Researchers collected opinion data over the course of several months in two separate waves – first with a late summer focus group and then with an October poll of 856 registered voters, conducted online.

Last week in conjunction with the well attended Marijuana Business Conference & Expo was the launch of a new business-centric webpage created to highlight the women and men of America’s nascent cannabis industry, as well as to foster needed B2B relationships and ‘best of industry’ practices among the many thousands of new cannabis-related businesses that have been founded in the last five years.
CannabisBusinessExecutive’s launch demonstrates a basic and continuing need by cannabis entrepreneurs for community and kinship in the fast growing and challenging new domestic cannabis industry, notably in the states of Alaska, Colorado, Oregon and Washington (where voters since 2012 have approved binding ballot initiatives replacing failed cannabis prohibition policies in favor of tax-n-regulate policies that look similar to existing alcohol policies).
Of note regarding CannabisBusinessExecutive’s unique content are three of it’s main features:

For the doubting Thomas that cannabis legalization is not gaining more and more cultural and commercial cachet in America (and the world), look no further than to the major corporate cannabis branding announcement EXCLUSIVE made yesterday morning on The Today Show during the show’s prime time (7:35AM).
After several decades of Reefer Madness propaganda dominating the discussion of marijuana in the media, it should be no surprise that many Americans, especially older Americans who are not personally familiar with marijuana, believe that “getting high” is somehow a bad experience, something to be avoided by responsible citizens. It is assumed that this experience is a waste of time, or even worse, that it somehow damages the healthy individual.
Yet, I have found that marijuana smoking has been a positive experience in my life, allowing me, when I am high, to stand back half-a-step and see my life in a clearer perspective. Yes, we all know that getting high is fun: food tastes better when one is high, and music sounds better and sex is even more enjoyable. But getting high is more than just pleasurable; in the right situation, it is an enriching experience.
Specifically, if I have something I need to write, whether an article for publication or the outline for a talk I am scheduled to deliver, I find it extraordinarily helpful to isolate myself in my home office for a few hours and get stoned, allowing my mind to freely wander, making notes of any seemingly insightful thoughts that result, jotting down whatever free-associations arise, and frequently discovering issues and new ways to analyze a topic that should have been obvious to me all along, but had not come to mind until I was high.
It’s as if the marijuana high eliminates some of the barriers we otherwise construct on our imagination and our creativity. Somehow, we appear to protect ourselves from the perceived risk of thinking out of the mainstream, by closing off some creative pathways. Marijuana can reopen those pathways, and give us new understanding.
