(Press-News.org) People who use both tobacco and cannabis are more likely to report anxiety and depression than those who used tobacco only or those who used neither substance, according to a new study published this week in the open-access journal PLOS ONE by Nhung Nguyen of the University of California, San Francisco, USA, and colleagues.
Tobacco and cannabis are among the most commonly used substances worldwide, and their co-use has been on the rise amid the expanding legalization of cannabis. In the new study, the researchers analyzed data on the substance use and mental health of 53,843 US adults who participated in online surveys as part of the COVID-19 Citizens Health Study, which collected data from 2020 to 2022.
Overall, 4.9% of participants reported tobacco-only use, 6.9% reported cannabis-only use, and 1.6% reported co-use. Among people in the co-use group, 26.5% reported anxiety and 28.3% reported depression, while among people who used neither tobacco or cannabis, percentages of anxiety and depression were 10.6% and 11.2%. The likelihood of having these mental health disorders were about 1.8 times greater for co-users than non-users, the study found. Co-use and use of cannabis only were also associated with higher likelihood of having anxiety compared to use of tobacco only.
This study cannot determine causation. However, the authors conclude that the co-use of tobacco and cannabis is associated with poor mental health and suggest that integrating mental health support with tobacco and cannabis cessation programs may help address this link.
The authors add: “Engaging in both tobacco and cannabis is linked to diminished mental well-being.”

High rates of depression and anxiety in people who use both tobacco and cannabis
Among more than 50,000 COVID-19 Citizen Science Study participants, around a quarter of users of both tobacco and cannabis experienced anxiety or depression – almost twice the rate of non-users

Battery-free robots use origami to change shape in mid-air
2023-09-13
Researchers at the University of Washington have developed small robotic devices that can change how they move through the air by "snapping" into a folded position during their descent.
When these "microfliers" are dropped from a drone, they use a Miura-ori origami fold to switch from tumbling and dispersing outward through the air to dropping straight to the ground. To spread out the fliers, the researchers control the timing of each device's transition using a few methods: an onboard pressure ...
Owners of cats on vegan diets report healthier pets than owners of meat-eating cats
2023-09-13
In a survey of cat owners, those who fed their cats vegan diets tended to report better health outcomes for their pets than those who provided meat-based diets, though the differences were not statistically significant. Andrew Knight of the University of Winchester, UK, and colleagues present these findings in the open-access journal PLOS ONE on September 13.
Many pet foods contain cooked meat as the primary protein source, but a growing number of available products use alternative protein sources, such as plants or fungi. Some veterinary professionals ...
Wolves and dogs appear to remember where people hid food
2023-09-13
In a study involving several wolves and dogs, both animals performed better at finding hidden food if they had observed the food being hidden by a person—suggesting that they remembered where the food was, and did not rely solely on scent to find it. Sebastian Vetter of the University of Veterinary Medicine Vienna, Austria, and colleagues present these findings in the open-access journal PLOS ONE on September 13.
Many species transmit important information through social learning, where one individual learns by observing ...

Six of nine planetary boundaries now exceeded
2023-09-13
A new study updates the planetary boundary framework and shows human activities are increasingly impacting the planet and, thereby, increasing the risk of triggering dramatic changes in overall Earth conditions.
For over 3 billion years, the interaction between life (represented by the planetary boundary, Biosphere Integrity) and climate have controlled the overall environmental conditions on Earth. Human activities, for example replacing nature with other land uses, changing the amount of water in rivers and in soil, the introduction of synthetic chemicals to the open environment, and the emission of greenhouse gases to the atmosphere ...

University of Liverpool researchers have secured £2.66m Medical Research Council funding to clinically test a novel immunotherapeutic strategy for non-small cell lung cancer – one of the most deadly cancers.
Professor Christian Ottensmeier, and Professor Natalia Savelyeva from the Institute of Systems, Molecular and Integrative Biology are collaborating with industry partner Genomics England and working closely with Touchlight Genetics Ltd to develop a vaccine therapy for patients with non-small cell lung cancer who have not had sufficient benefit from standard immunotherapy.
Non-small ...
