A new University of Michigan study finds that teens using marijuana for medical reasons are 10 times more likely to say they are hooked on marijuana than youth who get marijuana illegally.

The study is the first to report on a nationally representative sample of 4,394 high school seniors and their legal or illegal medical marijuana use as it relates to other drug use. In the study, 48 teens had medical marijuana cards, but 266 teens used medical marijuana without a card.

Researchers studying wild banded mongooses in Uganda have discovered that these small mammals have either cooperative or selfish personalities which last for their entire lifetime.

The researchers investigated the selfish behavior of mongoose mate-guarding - where dominant males guard particular females - and the cooperative behavior of 'babysitting' and 'escorting' the young.

They found that cooperative mongooses that helped out with offspring care did so consistently over their whole lifetime but those that put in little effort never increased their workload.

Similar consistent behavior was found in mongooses that selfishly guarded mates for their entire life.

In America there has been yet another shooting and the common denominator has been the presence of psychiatric medication. Clearly better diagnosis of people is not what is needed, better outcomes are. Medications are wildly over-prescribed and they don't work very well. For some patients, a nicotine patch is as effective as medication after two months.

In what they say is the first study that looks at a variety of healthcare providers and their implicit attitudes towards lesbian women and gay men, scholars say they have found there is widespread implicit bias toward lesbian women and gay men. 

Should doctors recommend homeopathy? Sometimes placebos work, that is why placebo has an Effect named after it and, because they are inert, they can't do any harm. But when patients or taxpayers are coughing up money for it, the issue is more murky.

Peter Fisher, Director of Research at the Royal London Hospital for Integrated Medicine, says that of all the major forms of complementary medicine, homeopathy is the most misunderstood. He says how regular medicine reviews homeopathy is. For example, in a recent report by the Australian National Health and Medical Research Council which stated that "there are no health conditions for which there is reliable evidence that homeopathy is effective." 

Youth from low-income families who succeed academically and socially may actually pay a price when it comes to their health, because relentlessly pursuing goals can undermine health.

When 21-year-old nurse Carol Felstead went to her doctor complaining of repeated headaches, she wasn’t just prescribed painkillers.

Instead, she was referred for psychotherapy that would ultimately involve hypnosis to “recover” so-called repressed memories of childhood sexual abuse.

We have known for some time the people suffering from schizophrenia and other psychoses smoke more than the general population.

Bringing reusable bags to the grocery store brings self-identification as an environmentally friendly shopper, but it also influences the things you buy, according to a new paper in the Journal of Marketing.

Reusable bags were correlated to organic food - no surprise there - but also junk food. 

Being busy with acts of kindness can help people who suffer from social anxiety to mingle more easily, according to a new stud. 

Sufferers from social anxiety are more than just a little shy. Dealings with others might make them feel so threatened or anxious that they often actively avoid socializing. Although this protects them from angst and possible embarrassment, they lose out on the support and intimacy gained from having relationships with others. They have fewer friends, feel insecure when interacting with others, and often do not experience emotional intimacy even in close relationships.
