The Real Cause For An Exercise High: Cannabinoids

For decades, endorphins have hogged the credit for producing “runner’s high,” that fleeting sense of euphoria and calm that many people report experiencing after prolonged exercise. Who among us, after an especially satisfying workout, hasn’t thought, “ah, my endorphins are kicking in.” Endorphins are the world’s sole celebrity peptide.

Endorphins first gained notoriety in exercise back in the 1980s when researchers discovered increased blood levels of the substance after prolonged workouts. (Endorphins, for those who know the word but not the molecules’ actual function, are the body’s home-brewed opiates, with receptors and actions much like those of pain-relieving morphine.) Endorphins, however, are composed of relatively large molecules, “which are unable to pass the blood-brain barrier,” said Matthew Hill, a postdoctoral fellow at Rockefeller University in New York. Finding endorphins in the bloodstream after exercise could not, in other words, constitute proof that the substance was having an effect on the mind. So researchers started to look for other candidates to help explain runner’s high. Now an emerging field of neuroscience indicates that an altogether-different neurochemical system within the body and brain, the endocannabinoid system, may be more responsible for that feeling.

Driving High on Marijuana Not an Impairment, Study Says

Despite what the nation’s “Drug Czar” Gil Kerlikowske might say and what his office might promote, it’s being proven that driving under the influence of marijuana does not make you a dangerous driver. In fact, a new study shows that it makes virtually no difference in the driving abilities of most drivers.

Of course, that may not be saying much given the state of some highways in this nation, but at least the road hogs and blind spot lurkers don’t drive any worse while high.

Most of the studies for stoned and drunk driving were conducted in the 1970s. Driving simulators, measurement tools, and even drug potency were different then. Although studies into drunk driving have continued to the present, studies of marijuana’s effects on driving have not. A new study from researchers at the Olin Neuropsychiatry Research Center has found that marijuana’s effects on driving – including separating data between men and women – is negligible.1

The research is legitimate, double-blind, placebo-controlled and used 85 subjects (50 men, 35 women) on driving simulators. Subjects were tested sober and then shortly after having smoked either a 2.9% THC marijuana joint or an identical placebo.

The only measurable difference in driving between those who were sober when stoned was that they tended to slow down and drive slower than otherwise. Which any safety advocate will tell you is almost always a good thing.

Other studies conducted overseas, including one in Israel published in 2008,2 showed similar results.

These studies and their findings should call into question every “impaired driving” law in which marijuana is treated the same as alcohol and hard drugs.

Of course, as marijuana becomes more and more socially acceptable and laws regarding its use loosen or are eliminated, a review of laws that lump it in with other, much more impairing drugs should be conducted as well.

Experienced Potheads Show No Change In Task Performance

If you’re going to smoke pot, for goodness’ sakes, smoke it every day, man.

Experienced marijuana consumers show virtually no changes in cognitive performance after using cannabis, according to clinical trial data published online this week in the journal Pharmacology, Biochemistry and Behavior.

Investigators at Columbia University in New York and San Francisco Brain Research Institute assessed acute marijuana-related effects on cognitive functioning in 24 volunteers who reported consuming cannabis at least 24 times per week, reports NORML.

Scientists found that participants’ overall performance accuracy on episodic memory and working memory tasks “was not significantly altered by marijuana.”

“The present findings show that smoked marijuana produced minimal effects on episodic and spatial working memory of near-daily smokers,” the researchers concluded.

Cannabis Reduces Infant Mortality

Salem-News reports on how cannabis use can reduce infant mortality. You would think that it would be equal or greater to the amount of deaths by a non-drug user. Although, the results show otherwise.

“It’s a sad little thing – an abstract of a study on the death of babies – yet vital facts can be learned from those soulless statistical studies. This one gave the infant death rates per 1,000 live births, and the drugs, if any, that the mother used during pregnancy.

A total of 2,964 babies were drug-tested at birth to see if they were positive for drugs – cocaine, opioids or cannabis were studied. 44% of the infants tested positive for all varieties of drugs, including the 3 being studied. During the first two years of their lives, 44 babies from the original group died. Since statistics are a drag to slog through, I’ll cut right to the chase – the deaths per thousand live births – the numbers tell the story.”

Some very shocking numbers are found.

“No drugs at birth” deaths……. 15.7 deaths per 1000 live births

“Cocaine positive” deaths…….17.7 deaths per 1000 live births

“Opiate positive” deaths…….18.4 deaths per 1000 live births

“Cannabis positive” deaths…. 8.9 deaths per 1000 live births
