Joshua Landy, a practising physician, came up with the idea for Figure 1 while enrolled at Stanford University in 2012, studying doctors’ smartphone habits. He launched the app in 2013 with two co-founders. As of September, Figure 1 had 500,000 users worldwide.

A new study finds that high-potency cannabis may damage nerve fibers in the brain.

An eye-opening new studying indicates that toking up might not always be a good idea.

The study, published by researchers at the Institute of Psychiatry at King’s College London, found that high-strength cannabis can damage nerve fibers that handle the flow of messages in the brain, based on scans of people who regularly smoked strong marijuana, according to a Guardian report.

It’s the Institute of Psychiatry at Kings College London, yet again, with another terrifying story about cannabis that is immediately distorted, exaggerated and misrepresented by the scientifically illiterate hacks of Fleet Street.

This time though King’s College itself has reported the results of its own research inaccurately and published false and misleading claims.

LONDON, Nov. 27 (UPI) -- In scanning the brains of drug users, researchers at Kings College London found smokers of high-potency pot had smaller amounts of white brain matter inside their corpus callosum, a neural pathway connecting the left and right halves of the brain.

While pot smokers generally showed more damage to the corpus callosum than non-smokers, those who smoked super strong weed known as 'skunk' showed more significant white matter loss.

Scientists performed MRI scans on the brains of 56 patients who had visited a London hospital reporting a first episode of psychosis. The brains of 43 healthy participants were also scanned. All the participants were surveyed about their drug habits.

Children who were exposed to marijuana in the womb have better vision by the time they are four years old, a new study has revealed.

But, scientists were quick to warn the results do not mean cannabis has a beneficial effect on foetal development. 

The team from the University of Waterloo, Auckland and Brown University, admitted they were surprised at their findings, which show the drug can improve a child's ability to track moving objects in their line of sight.

Professor Ben Thompson, at the University of Waterloo, Ontario, said: 'We were surprised with this initial finding.

Marijuana may contain a chemical that can help fight cigarette addiction, according to new research out of Britain.

Researchers at the University College London found that a non-psychoactive chemical in marijuana, cannabidiol (CBD), given via inhaler could significantly reduce the number of cigarettes consumed by smokers that wanted to quit.

Celia Morgan, Ph.D, who co-authored the study, explained that CBD may help in a number of ways. One way could be how it affects memories, or cues, that underlie the desire to smoke.

As the legalization of recreational and medical cannabis continues to spread, so is awareness for its many healing properties. And though active compounds known as cannabinoids have been hogging the limelight, there’s another category of compounds that are yet to be similarly appreciated by consumers and chemists alike.
