Problematic smartphone use linked to poorer grades, alcohol misuse, more sexual partners

A survey of more than 3,400 university students in the USA has found that one in five respondents reported problematic smartphone use. Female students were more likely be affected and problematic smartphone use was associated with lower grade averages, mental health problems and higher numbers of sexual partners.

Smartphones offer the potential of instant, round-the-clock access for making phone calls, playing games, gambling, chatting with friends, using messenger systems, accessing web services (e.g. websites, social networks and pornography), and searching for information. The number of users is rapidly increasing, with some estimates suggesting that there are now more than 2.7 billion users worldwide.

While most people using smartphones find them a helpful and positive part of life, a minority of users develop excessive smartphone use, meaning that smartphone use has significant negative effects on how people function in life. Previous research has linked excessive smartphone use to mental health issues such as anxiety, depression, post-traumatic stress disorder (PTSD), attention deficit hyperactivity disorder (ADHD) and problems with self-esteem.

A team that Dr. Paulo Lizano — of the Beth Israel Deaconess Medical Center in Boston, MA — led has now investigated this vital structure.

In doing so, they found that there could be a link between its size and the development of psychosis.

Can Rick Simpson oil help treat cancer?

Rick Simpson oil is a cannabis extract that takes its name from the medical marijuana activist who created it. Simpson claims that applying the oil to cancer spots on his skin cleared the spots within days.

Although there is some evidence to support the use of cannabis for aiding cancer treatment, the medical community needs more direct evidence of its safety and effectiveness in humans before making any firm claims.
