Years-worth of smoking pot might make you forget words in middle age

Researchers looked at the long-term exposure of marijuana on cognitive skills. Current users showed poorer cognitive ability across all the mediums the researchers tested. What was interesting is that among those who reported not using marijuana anymore, but used to, there was a pattern that suggested poorer verbal memory, which the ability to remember words. For every five year of cumulative marijuana use (365 days of smoking pot x 5), one in two people on average remembered one word fewer out of a list of fifteen.

Twice as many Americans use pot than 10 years ago

Marijuana use has doubled among American adults from 2001 to 2013. About 10% of the population or 22 million are believed to be recreational users, a steep rise driven by both cultural shifts and more permissive laws. About 1 in 3 users abuse the drug (continued use despite knowing it may be damaging health or causing depression or anxiety), though it's worth mentioning that this ratio was the same before the exponential rise in marijuana users.

First long term study on medical cannabis shows only small adverse effects, but also small reductions in pain

A new study conducted on medical consumption of cannabis came up with some good news, and some bad news: for starters, while there were some adverse effects on consumers, no serious effects were reported. However, the reduction in pain also seems to be very small.

Cannabis traces found on Shakespeare's pipe - was the bard into pot?

William Shakespeare – universally praised as one of the best writers in history, eminent dramatist and England’s national poet, is still a controversial figure. There is speculation about the authorship of his works, with some scholars claiming they were written by someone else; there’s also speculation about his sexuality, his religion, and even his looks. Contrary […]

Medical Marijuana benefits are largely unproven and poorly documented, study finds

An extensive meta-analysis of 79 trials which studied the medical benefits of marijuana found that the various cannabinoid compounds did not improve nausea, vomiting, or appetite, but slightly improved chronic pain and plasticity. Moreover, most of the studies were poorly made, lacking control or placebo groups and also showing increased risk of bias. In short, this rigorous analysis found no conclusive evidence that supports the much heralded added benefits of medical marijuana. Side effects were common and included dizziness, dry mouth and sleepiness. The authors note that this doesn't mean that marijuana compounds aren't working as advertised, it's just that the science so far is inconclusive - mainly because of bad reporting and investigative techniques. They suggest more research is necessary, along with more support from the authorities and other able bodies given that we're talking about an extremely widespread drug ingested by millions of Americans each day, legally or not.

These amazing pictures which size up the planet’s crystals, trichomes or leafs were taken by Ford McCann and compiled in a book called  Cannabis […]

Smoking skunk might triple the risk of psychosis

South Londoners who smoke skunk weed - a much more potent strain of cannabis - were found to be three times more likely to register at hospitals with first-episode psychoses, according to a study made by British researchers. The research has many shortcomings though, as is to be expected from a case-control design where it's always difficult to account for external variables. As the old saying goes, correlation does not equal causation, so take these findings with a grain of salt. The study is valuable however considering it's among the few which actually considered the relationship between cannabis use and psychosis, often ignored by mainstream cannabis research. Cannabis is used by millions of people worldwide, yet its long-term effects are seriously under reported.

Cannabis Consumption Might Make You Bipolar

After reviewing existing literature and statistics, researchers from the University of Warwick have found evidence which suggests a significant relationship between cannabis consumption and the onset (or exacerbation) of mania symptoms. We’ve presented quite a few studies on cannabis here on ZME Science. Our general impression is that due to legal constraints (which are somewhat […]

Chronic marijuana use could be avoided by inherent brain 'high'

People who chronically abuse marijuana may be able to quit by replenishing the supply of a molecule that normally activates cannabinoid receptors in the brain, thus reducing anxiety and relieving mood. A truly natural high In the 1980s and 90s, researchers identified cannabinoid receptors, long, ropy proteins that weave themselves into the surfaces of our […]

Scientists explain the munchies: it's all about smell

It’s one of the most known effects of marijuana – you get a powerful surge in appetite (especially a craving for sweets) after smoking (or inhaling or ingesting the drug) – something colloquially referred to as “the munchies”. While for casual users this is a minor and not troubling side effect (often times even enjoyable), […]

Heavy marijuana use causes poor memory and abnormal brain structure, study concludes

We’ve written a number of times about the advantages that cannabinoids can bring – how they can become effective pain killers even without the high, how they don’t harm the lungs when smoked, and many more.

Marijuana addiction and abuse treatment shows promising results

Actually, there is no physical way to overdose on smoked or ingested cannabis, making it basically one of the safest, most natural, non-toxic painkillers, sleeping aids, and stress relievers on the planet. However, […]
