Not an Endorsement, Say Docs

1 Occasional Marijuana Use May Not Harm Lungs

Occasional marijuana use may not harm lungs, says a University of California at San Francisco study that finds that the lung capacity of people who smoke marijuana was not lessened for those who smoke once or twice a week. However, the lung function of heavy users - those who smoke 20 or more joints/month - was diminished. Researchers say this information, which disproves one of the major concerns of marijuana - that it’s as harmful as tobacco - may be due to the fact that people don’t smoke as many joints as they do cigarettes. Researchers warn that the study is not an endorsement for marijuana use, which they say is not totally harmless. Smoking any combustible organic material is harmful to lungs says, pulmonologist Dr. Stephen Ruoss, who was not involved with the study.

Give Your Feet a Break

2 High Heels Could Cause Painful Flat Feet

Adult-acquired flat feet is a painful condition that is common to women over the age of 40. It is caused by the gradual stretching-out of the tibialis posterior tendon, the main stabilizer of the foot arch. Researchers believe that wearing high heels and standing or walking could play a role in this process. The theory is that increased activity of this tendon from these conditions increase the activity of some enzymes which break down and weaken the tendon, causing the arch to fall. Flat feet, also known as pes planus, rarely cause complications aside from pain, but if needed, special shoes (orthotics) or surgery are currently the only treatments. However, this new finding could potentially lead to the development of a new drug therapy.

Too Much of a Good Thing?

3 High Vitamin D Levels Tied to Heart Problems

While previous research has shown that normal vitamin D levels are linked to a reduced risk of cardiovascular inflammation, atherosclerosis and death due to heart disease, higher levels may actually increase the risk of heart problems. Information from surveys of over 15,000 adults in the U.S. was gathered and it was noted that the blood marker for cardiovascular inflammation, c-reactive protein (CRP), was higher in individuals when vitamin D levels go above the low end of the normal range. Increased CRP elevates the risk of heart problems. The relationship between high vitamin D and heart problems is not known at this time, but researchers want people to make sure that they know the potential risks and take vitamin D supplements only if it is necessary.
