Smoking cigarettes is well known to cause lung damage, but this is not only due to smoke. Nicotine in whatever form - even nicotine replacement therapies like a patch - causes lung inflammation and fibrosis by activating acetylcholine receptors. Polish scientists recently examined how the endocannabinoid system fits into the picture. Activating the CB2 receptor ameliorated nicotine-induced fibrosis, while blocking the receptor exacerbated the problem. Fibrosis involves the accumulation of a protein called collagen between cells.
On November 16, 2017, California officials released a new set of regulations for cannabis manufacturing, testing, and growing. In many respects, these updates are a significant improvement to the initial draft regulations, however, some major problems remain.
Two important issues pertain to regulations on mold and foreign filth, which are absurdly loose. And unlike the initial proposal, no statement as to the rationale behind the new regulations has been released.
During the last week of June, more than 400 scientists from 25 countries met in Montreal for the 27th annual symposium of the International Cannabinoid Research Society (ICRS). Several presentations and posters showcased new findings about cannabidiol (CBD), the non-euphoric component of the cannabis plant that is transforming the medical marijuana landscape.
A patient survey collaboration between Care by Design and Project CBD demonstrated that cannabis appears to be an effective pain management tool with few negative side effects. The study also found that a significant decrease in opiate usage among elderly patients while taking medical cannabis.
Misinformation can masquerade as science, especially when it comes to cannabis. Adrian Devitt-Lee highlights how analysis can be skewed for a variety of factors and gives insight on how to spot faulty research data.
Numerous plants – not just cannabis – are endowed with compounds that interact directly or indirectly with the endocannabinoid system. The health benefits of many common kitchen spices are mediated by the same cannabinoid receptors in the human brain and body that marijuana activates.
Project CBD science advisor Jahan Marcu, PhD, reports on the hidden dangers of propylene glycol and vape pens that smolder.
The role of the endocannabinoid system in nicotine addiction is being increasingly acknowledged. Researchers conducted a pilot, randomised double blind placebo controlled study set out to assess the impact of the ad-hoc use of cannabidiol (CBD) in smokers who wished to stop smoking.
You’d think it would have been very big news in the spring of 2005 when Donald Tashkin, a professor of pulmonology at UCLA, revealed that cannabis smoke doesn’t cause lung cancer and may prevent respiratory tissue cells from becoming malignant.
