1/3/20--USA Today health policy writer Jayne O'Donnell started covering vaping lung injuries from high-potency THC in August, then added the link between cannabis and mental illness, as well as marijuana, psychosis, and other mental illness. O'Donnell indicates that this type of coverage presents a pretty solitary place to be. According to former Food and Drug Administration chief Scott Gottlieb, the news media seemed to lose interest once it became clear that the culprit to vaping lung illnesses was THC and not nicotine. Former New York Times business reporter Alex Berenson adds that the human cost of cannabis is too high — and that the press is too pro-pot. Read

A California panel voted Wednesday to declare marijuana smoke and the drug's high-producing chemical — THC — a risk to pregnant women and their developing fetuses and require warning labels for products legally sold in the nation's largest pot market. The decision by the little-known Developmental and Reproductive Toxicant Identification Committee will not take effect for a year, and it remains to be seen what impact it will have on the state's emerging marijuana industry. Read

12/9/19--The goal of this study was to determine whether cannabinoids can be quantitatively detected on room surfaces exposed to side-stream cannabis vapor, making these surfaces possible sources for third-hand exposure. Study results show that in a room in which cannabis was administered by vaporization, surfaces tested positive for THC at quantifiable levels. This study represents a first step in understanding how side-stream cannabis vapor deposits in the environment and may result in tertiary exposure to users and bystanders. Read

6/23/19--Cancer cachexia (CCA), an intractable and ineffective metabolic syndrome that attacks 50–80% of cancer patients, reduces patient’s life quality, affects the efficacy of treatment, and then increases their mortality. However, there are no established therapeutic strategies for CCA in the world. In this study, the positive and negative effects of cannabinoid in the treatment of CCA are assessed. Results showed cannabinoid is effective in increasing appetite in cancer patients; however, it declines the quality of life, which may be due to the side effects of cannabinoid. Read

6/16/19--The first two states to legalize recreational marijuana are starting to grapple with teenagers’ growing use of highly potent pot, even as both boost the industry and reap huge tax windfalls from its sales. As more than a dozen states from Hawaii to New Hampshire consider legalizing marijuana, doctors warn of an urgent need for better education — not just of teens but of parents and lawmakers — about how the products being marketed can significantly affect young people’s brain development. Read

6/16/19--Numerous studies show that marijuana can have a deleterious impact on cognitive development in adolescents, impairing executive function, processing speed, memory, attention span and concentration. The reason the adolescent brain is so vulnerable to the effect of drugs is that the brain is still developing in adolescents and young adults until age 25. Read
