The discovery, published in the September issue of Addiction in 2012, is the result of the first-ever study on the impact of foreign cigarette smoke on brain The camera. Dr Tom Heffernan and Dr Terence O’Neill, researchers on drug and alcohol abuse at Northumbria University made a comparison between a group of active smokers and smoking two groups: one composed of people who are regularly exposed to secondhand smoke and group to avoid smoke at all costs. Researchers reported average exposure to cigarette smoke in the last four years in the group of non-smokers in the order of 25 hours.
The study is carried out time-based assays, where the aim is to carry out a command after a certain period of time and the event-based testing of the memory in which the participants had situations to respond appropriately by use of recorded data.
Researchers found that smokers who were exposed to cigarette smoke are wrong a lot more than those who had no contact with him. On average, passive smokers forget 20% more than the group without contact with secondhand smoke. Active smokers did forget about 10% more than the passive and 30% higher than abstainers.
Dr Heffernan stresses that even the World Health Organization takes action against secondhand smoke. It has serious implications for the health of people who have never smoked in my life, but they are constantly exposed to cigarette smoke.
In another study from the same year Dr. Gary Kziao by the Center for Research on Cancer, along with his team is how cigarette smoke damages the bones of non-smokers. Only three substances carcinogenic cocktail of smoke show shared and mutually reinforced effect on bone tissue. They strongly inhibit the activity of Osteoblasts – cells that build new bone and, if not strengthen, at least leave intact the activity of Osteoclasts – cells that break down old bone. This effect leads to a gradual loss of bone density and consequently – osteoporosis, even with good eating habits and sport activity.
In the studied group of patients with osteoporosis, over 11% of them were diagnosed as “ill due to secondhand smoke.”
