Subjects who regularly inhale cannabis smoke possess no greater risk of contracting lung cancer than do those who consume it occasionally or not at all, according to data published online ahead of print in the International Journal of Cancer.
An international team of investigators from Canada, New Zealand, the United Kingdom, and the United States analyzed data from six case-control studies involving over 5,000 subjects (2,159 cases and 2,985 controls) from around the world.
Authors concluded, “Results from our pooled analyses provide little evidence for an increased risk of lung cancer among habitual or long-term cannabis smokers.”
Investigators had previously presented their data at the 2013 annual meeting of the American Academy for Cancer Research.
Their findings are similar to those of a 2013 review published in the journal Annals of the American Thoracic Society, which concluded: “[H]abitual use of marijuana alone does not appear to lead to significant abnormalities in lung function. … Overall, the risks of pulmonary complications of regular use of marijuana appear to be relatively small and far lower than those of tobacco smoking.”
An accompanying commentary in the same journal affirmed, “[C]annabis smoking does not seem to increase risk of chronic obstructive pulmonary disease (COPD) or airway cancers. In fact, there is even a suggestion that at low doses cannabis may be protective for both conditions.”
Preclinical studies have documented that cannabinoids possess potent anti-cancer properties, including the inhibition of lung cancer cell growth. To date, however, scientists have yet to conduct controlled clinical trials replicating these results in human subjects.
The abstract of the study, “Cannabis smoking and lung cancer risk: Pooled analysis in the International Lung Cancer Consortium,” appears online here.
Like many marijuana smokers, I’m always fascinated when I travel to other states, especially on the West Coast, and see the popularity of edibles and concentrates, especially the somewhat bizarre practice of “dabbing.”
Now let me be clear that I enjoy getting high, and I’m generally willing to try any variation of marijuana, at least once, just to see what it’s about. So I’m not making a moral judgment on the use of these more potent forms of marijuana. I will also concede that I personally love smoking flowers, and prefer the quality of a flower high to that of the concentrates.
But that’s simply a personal preference shaped by decades of rolling and smoking joints. I’m an old guy and somewhat set in my ways.
What I want to discuss in this column is the potentially adverse political fallout from the increasing popularity of these newer, more potent forms of marijuana. Specifically, I want to sound the alarm that the perceived abuses of edibles and concentrates have the potential to undermine the powerful political momentum we have achieved for full legalization, by frightening many of our supporters–particularly the non-smokers–and causing them to reconsider their positions on cannabis reform.
New York State lawmakers announced today that they have come to agreement to approve a limited pilot program for medical marijuana in the Empire State.
An agreement was reached to amend the bill to include provisions demanded by Democratic Governor Andrew Cuomo, including provisions that prohibit the smoking of marijuana. Instead, the amended measure is expected to only allow for non-smoked preparations of cannabis (such as oils). The compromised measure also reduces from the original bill of the number of qualifying conditions, as well as the total number of state-licensed producers and dispensers that will be allowed. (A final draft of the compromised language has not yet been made public.)
The pilot program will be overseen by the State Health Department and would last for seven years, with the option to reauthorize the program after that period has expired. After final approval, the State Health Department will have up to 18 months to establish regulations and authorize entities permitted to dispense it. The governor, upon recommendation by the state police superintendent or the state health commissioner, would have the authority to suspend the program.

Senate members are expected to vote imminently in regard to language that seeks to bar the US Justice Department from interfering in activities that are compliant with state medical cannabis laws.
Senators Rand Paul (R-KY) and Cory Booker (D-NJ) will introduce the bipartisan amendment, which will be similar to language approved by the US House of Representatives earlier this month. As with other legislation, the amendment must be approved by majorities in both legislative chambers before it is sent to the President for approval.
This will be the first time in recent memory that US Senators have ever decided on provisions specific to liberalizing America’s marijuana policies.
It is time that we allowed our unique federalist system to work the way it was intended. Patients and providers should be permitted to engage in state-sanctioned, medical cannabis-related activities free from the threat of federal interference or federal prosecution.
Please write or call your members of Senate today and tell them to stop using taxpayer dollars to target and prosecute state-authorized medical marijuana patients and providers. For your convenience, a pre-written letter will be e-mailed to your Senators when you visit here.
Today, the full Philadelphia City Council voted 13 to 3 in support of a measure that would lower the penalty for possession of up to one ounce of marijuana to a civil infraction, punishable by a $25 fine.
All 13 of the Democratic members of the City Council voted for it and all three Republicans voted against. The measure now goes to Philadelphia Mayor Nutter’s desk for signature. NORML’s local chapter, Philly NORML, has been working hard on advancing these reforms for many years and those efforts seem to be finally paying off.
Councilman Bill Greenlee, who voted in support of decriminalization, stated, “It does not seem fair for what most people consider a minor incident to potentially risk people’s future.”
Councilwoman Cindy Bass, who also voted “Yes” on the bill, said, “To spend the time and the amount of money that is really required to prosecute someone with small amounts of marijuana, while we have so many other bigger issues in the city, does seem a little bit not where we need to be headed.”
Bill sponsor Councilman Jim Kenney estimates that the new pot policy could save the police department and the courts about $4 million a year.
NORML will keep you updated if and when the mayor signs this measure.
