Much less is known about the effects of smoking on subcortical regions. We compared smokers and non-smokers on regional subcortical volumes, and predicted that smokers demonstrate greater age-related volume loss across subcortical regions than non-smokers. Non-smokers (n = 43) and smokers (n = 40), 22–70 years of age, completed a 4 T MRI study. Bilateral total subcortical lobar white matter (WM) and subcortical nuclei volumes were quantitated via FreeSurfer. In smokers, associations between smoking severity measures and subcortical volumes were examined. Smokers demonstrated greater age-related volume loss than non-smokers in the bilateral subcortical lobar WM, thalamus, and cerebellar cortex, as well as in the corpus callosum and subdivisions. In smokers, higher pack-years were associated with smaller volumes of the bilateral amygdala, nucleus accumbens, total corpus callosum and subcortical WM. Results provide novel evidence that chronic smoking in adults is associated with accelerated age-related volume loss in subcortical WM and GM nuclei. Greater cigarette quantity/exposure was related to smaller volumes in regions that also showed greater age-related volume loss in smokers.

Making cigarettes affordable for our youths and children will clearly result in far greater repercussions than we can imagine. 3. Every year, more than 20,000 Malaysians are killed by tobacco-related diseases. Studies show that more men and women die in Malaysia from tobacco-related diseases than on average in middle-income countries. What is more alarming is that you don’t need to be a smoker to be at risk. The Global Adult Tobacco Survey 2012 on Malaysia revealed that four out of 10 adults were found to be exposed to secondhand smoke at home (7.6 million adults), and four out of 10 were found to be exposed to secondhand smoke indoors at their workplace (2.3 million adults). Among those adults who visited a restaurant in the past 30 days, seven out of 10 would have been exposed to secondhand smoke (8.6 million adults). 4. Another critical area of consideration is economics. Tobacco use reduces overall national incomes by up to 3.6%.
Cal Poly to be smoke-free - KSBY.com | San Luis Obispo and Santa Barbara Area News Cal Poly will become a smoke-free campus before the start of the new school year. Starting September 1, smoking will no longer be allowed on campus. Signs are posted on the sides of ash trays advising the campus community of the upcoming change. "I actually just heard right now, so yeah, I'm very surprised. Kind of shocked but hey, maybe it's good for all of us," said Cal Poly student Mateo Cuellar. The new policy is in response to a systemwide CSU Executive Order issued in April. Chancellor Timothy White directed that all 23 campuses be smoke and tobacco-free September 1st. Right now, there are 73 designated smoking areas at Cal Poly. Student Ellie Vutova says too many students smoke. She believes the new policy is a good idea. "Hopefully it will curb their bad habits but honestly, I'm sure they might just smoke anyway," said Vutova.
