Around 10,000 years ago prehistoric humans began using cannabis, a new research study has found, and not just in one small corner of the globe.

It’s easy to explain the appeal of drugs like heroin and cocaine, which directly stimulate the brain’s reward centres. What’s less easy to explain is the appeal of psychedelic drugs such as LSD and psilocybin that produce altered states of consciousness. After all, there’s no obvious reason why unusual patterns of thought and perception – typically, the symptoms of poisoning or illness – should be attractive. And yet, people not only pay money for these experiences, they even run the risk of being imprisoned or worse for doing so. Why is this?

Cannabis, hemp or marijuana is our oldest crop, sown for over 12,000 years (1), and may have been domesticated over 30,000 years ago. It produces more fuel, fiber, food and medicine than any other plant (2). The seeds of cannabis produce the most productive and nutritious vegetable oil and protein (3). Hemp produces more fiber, from its stems and stalks, than any other plant (4), and hemp fiber can be used to make paper, canvas, rope, lace, linen, building materials and more. Cannabis flowers and leaves also produce over 100 unique compounds known as cannabinoids that have many physical and psychological effects. (5)

In April 2016, the international community will convene for the United Nations General Assembly Special Session on the World Drug Problem (UNGASS). This event, held two years early due to the urgency of the drug situation and intensity of drug-related violence, presents an opportunity to question the fundamentals of international drug policy. Despite overwhelming evidence that a century-long quest to control human behaviour and drug markets through international treaties and national legislation has failed, there is little expectation of change. The vested interests in retaining the status quo are significant, with sclerosis legitimised through the recurrent exhortation to improve international co-operation.

Although the Koran does not specifically outlaw cannabis, and it was apparently never mentioned by Mohammed himself, the plant and products made from it are still considered haraam (forbidden). However, cannabis grows and is processed into hashish in many Muslim-majority countries around the world, and it has been an undeniable part of the culture for centuries in many of these countries.  

March 8 is International Women's Day, celebrated in today's Google Doodle with a video asking women all over the world to finish the sentence, "One day I will..."

The answers run the gamut from personal dreams like "play in the Major Leagues" to more global aspirations like Malala Yousafzai's wish to "see every girl in school." And like International Women's Day itself, the video is both a celebration of women's lives and achievements, and a call to action to make their lives better.

What is International Women's Day?

These days, it's a corporate-sponsored global campaign to raise awareness of women's issues worldwide.

Ladies, to celebrate International Women’s Day we wanted to explore how independent women, and the characters they’ve inspired, have been celebrated on the silver screen. Below are our top picks for some great flicks to get you in the mood for IWD. 

The Accused (1988)

When Sarah (Jodie Foster) fights back against the men who brutally gang-raped her, she must not only face the men she accuses, she must defend herself against society’s deeply embedded view that ‘she was asking for it.’

Pot. Cannabis. Mary Jane. The plant with psychotropic properties has a long pop culture presence — and an even longer record of use.

1. Pot. Weed. Mary Jane. Sticky-icky. Nicknames aside, much of the world calls the psychotropic plant by its scientific name, cannabis, and — until the early 20th century — so did Americans.

2. About a hundred years ago, however, the term marijuana became common in the United States, the result of anti-cannabis, anti-immigrant advocates trying to link recreational use of the plant to migrant workers from Mexico.

A police chief on the small tropical volcanic island of Lihir in Papua New Guinea’s New Ireland province has launched a campaign to purge the community of marijuana cultivation.

Lihir police station commander Senior Inspector Elizah Taksir has made an appeal for islanders to report marijuana growers following information received about people engaging in illegal activities.

Taskir said the police woudl be keeping a look out for those cultivating marijuana and despite the fact that the police on Lihir had limited resources, they would still monitor the illegal activities and arrest those involved.
