Marijuana Addiction in the Age of Legal Weed

Addiction, Marijuana, research

Generation X writer Neal Pollack thought he had it all: a good writing career, a strong marriage, even a lucrative 3-day run on “Jeopardy”! That brought him national attention. Like many in his generation, he also smoked a lot of marijuana. He had discovered that food, music and even his beloved yoga was much better when he smoked. In 2014, as several states in the country legalized pot, Pollack scored a writing gig for a marijuana site that provided free weed. He saw his drug use as harmless and joked about it often in his writing. But as more states, including California, began to legalize the drug, Pollack’s life began to fall apart, in part because of his drug use. Both of his parents died and he soon found himself spiraling out of control, sometimes in public. By 2018, Pollack admitted publicly he had a marijuana addiction and set about to conquer it, through honesty . . . and humor. Pollack’s new book, Pothead, is about coming to terms with his marijuana problems just as the country increased its recreational availability. The book is a cautionary and timely tale for those who think the drug isn’t dangerous and can’t cause serious addictive problems. Join us for a special evening program as Pollack discusses his story with Los Angeles novelist Bucky Sinister.

By placing dogs in an MRI scanner, researchers from Hungary found that the canine brain reacts to voices in the same way that the human brain does. Emotionally charged sounds, such as crying or laughter, also prompted similar responses, perhaps explaining why dogs are attuned to human emotions.

The work is published in the journal Current Biology. The full article is @ BBC.

Eleven pet dogs took part in the study; training them took some time. “We used positive reinforcement strategies – lots of praise,” said Dr Andics. “There were 12 sessions of preparatory training, then seven sessions in the scanner room, then these dogs were able to lie motionless for as long as eight minutes. Once they were trained, they were so happy, I wouldn’t have believed it if I didn’t see it.”

Sad Music

research, sadness

A team of psychologists from the Free University of Berlin in Germany decided to investigate the science behind the lure of the melancholy tune by analyzing how they make us feel. They gathered data from 772 participants, including 408 from Europe and the rest from Asia, and North America. Each participant was asked to respond to a survey about how often they listen to sad music, what kinds of situations prompted them to do so, and how they feel when they’re listening to it.

Publishing in the journal PLOS One, the researchers found that “a wide range of complex and partially positive emotions, such as nostalgia, peacefulness, tenderness, transcendence, and wonder,” were brought out in the participants by sad music. The data revealed that nostalgia was the most prevalent emotion, brought out in over 76 percent of the participants, while peacefulness came in second place at 57.5 percent.

What do nostalgia, peacefulness, tenderness, transcendence, and wonder all have in common? They’re all healthy, feel-good emotions. “For many individuals, listening to sad music can actually lead to beneficial emotional effects,” the researchers, led by psychologist Liila Taruffi, report. “Music-evoked sadness can be appreciated not only as an aesthetic, abstract reward, but [it] also plays a role in well-being, by providing consolation as well as regulating negative moods and emotions.”

The study also revealed that a high number of participants reported listening to sad music in situations of emotional distress or when they’re feeling lonely, so it could be a form of self-medication. “For most of the people, the engagement with sad music in everyday life is correlated with its potential to regulate negative moods and emotions, as well as to provide consolation,” the researchers add.

These findings appear to have some connection to previous research into sad music that suggests listening to it changes the chemistry in our brains to help us get over our grief. According to David Huron, a professor of music at Ohio University in the US, listening to sad music likely causes a spike in the hormone prolactin in the brain.

“Prolactin is the chemical that is used to help curb grief because it’s also released during basic human activities – like when we eat, when women ovulate or breastfeed and (perhaps most importantly) when we have sex,” says David Taylor Sloan at Mic.com. “So sad music actually activates a chemical that tones down your grief – suggesting that being sad (and listening to sad music to get there) has deep evolutionary benefits.

What we know about habits is wrong

habits

DESPITE the our intentions the reality is that often our gym memberships will lapse, chocolate will replace carrots and Candy Crush will edge out Moby Dick.Tricep Stretch

It’s not (only) that we’re undisciplined slugs. It’s that much of what we know — or think we know — about habits is wrong. Here’s a primer that might help keep you off the couch and on the treadmill.

MYTH 1 We fail to change our habits — or start good new ones — because we lack willpower.

Not really, said Wendy Wood, a professor of psychology and business at the University of Southern California. Willpower, she said, is more about looking at those yummy chocolate chip cookies and refusing them. A good habit ensures you’re rarely around those chocolate chip cookies in the first place.

To create or change a habit, you have to think much more about altering your environment and patterns of living than work on steeling your mind, Professor Wood said, because “behavior is very much a product of environment.”

Habits — at least good ones — exist so we don’t have to resist temptation all the time. Imagine if every morning you had a debate with yourself about eating cake or cereal for breakfast. Instead, most of us form the habit of eating something relatively healthy for breakfast, which bypasses the lure of the cake altogether.

That’s why it’s sometimes easiest to start or break a habit during a major transition. This may sound counterintuitive, but a new house, job or relationship breaks old patterns, said Gretchen Rubin, author of the forthcoming book, “Better Than Before: Mastering the Habits of Our Everyday Lives.”

“People say wait a few days to get settled, but don’t,” she said. “Start right away.”

MYTH 2 We fall back on bad habits when stressed. In fact, good habits persist even in times of high anxiety, Professor Wood said. A study of which Professor Wood was one of the co-authors found that students who already had unhealthy diets would eat junk food when stressed, but those who already had the habit of eating well — or of reading a newspaper or of going feelings-54to the gym — were just as likely to do that.

MYTH 3 It takes about 21 days to break or make a habit.

That number seems to have cropped up in the 1960s and somehow became “fact” with no real proof. But in 2009, researchers in Britain decided to take a deeper look by studying how long it took participants to learn new habits, such as eating fruit daily or going jogging. The average was 66 days.

But individuals’ times varied greatly, from 18 days to 245 days, depending on temperament and, of course, the task involved. It will most likely take far less time to get into the habit of eating an apple every afternoon than of practicing the piano for an hour a day.

MYTH 4 You need positive thinking to break or make a habit.

“We find positive fantasy is not helpful and may even be hurtful when trying to reach a desired future or fulfill a wish,” said Gabriele Oettingen, a professor of psychology at New York University and the University of Hamburg.

Over years of research, she discovered that people need to pair optimistic daydreams about the future with identifying and imagining the obstacles that prevent them from reaching that goal — something she calls mental contrasting.

Say you want to stop being a procrastinator. The first step is easy. Imagine how it will feel if your work is completed with plenty of time to spare, if you can sleep instead of pulling an all-nighter, said Professor Oettingen, author of “Rethinking Positive Thinking.”

But don’t just resolve to stop procrastinating. The second step is to identify what holds you back from changing yourself. Is it fear that you won’t succeed? Is it the adrenaline rush of frantically working at the last minute? Is it because of negative feelings toward a boss or teacher?

The mental contrasting needs to be in the right order. It’s important to “experience our dreams, then switch gears and mentally face reality,” Professor Oettingen said.

Doing it the opposite way — imagining the obstacles and then fantasizing about changing habits — doesn’t seem to work as well, research shows.

MYTH 5 Doing things by rote, or habit, isn’t good in most cases. It’s better to be mindful of everything we do.

Research shows that most people repeat about 40 percent of their activities almost every day.

“We only have so much room in our brain,” said Ian Newby-Clark, an associate professor of psychology at the University of Guelph in Canada. “It would be incredibly taxing if we had to mindfully plan every step of our day.” Habits free us up so we can think about other things.

And while some habits are objectively bad — smoking, say, or being consistently late — most are subjective. “Habits are only good or bad to the extent they’re consistent or inconsistent with your goals,” Professor Wood of U.S.C. said. It’s a bad habit when “it starts interfering with other goals you have.”Creative minds 'mimic schizophrenia'

For example, many people said their resolution this year was to cut down the time they spend online.

But why? Because it’s an inherently bad thing to do? Or is it an obstacle to spending more time reading books or riding a bike or learning to knit?

After thinking about it, you may choose to spend less time on your computer or phone. Or you might decide it’s not so terrible in limited doses and shed the habit of feeling guilty about it.

MYTH 6 Everything in moderation.

“There’s a real difference among people about how easily they adapt to habits,” Ms. Rubin said. Some see habits as liberating; some see them as a trap. Some prefer to make a huge change all at once; others proceed step by step.

“I’m in the small minority that loves habits,” Ms. Rubin said, adding that she tends to find it easier to abstain from certain things altogether. For example, she eats no carbohydrates.

“People said I was doomed to failure, but it’s not true,” she said. But, she noted, “it’s a mistake to think the abstainer is more disciplined. For me it’s easier to be an abstainer than have to deliberate each time whether I can eat something or not. Others would go nuts if they abstain.”

That’s why you shouldn’t listen to people who tell you you’re doing it wrong if it works for you, she said.

Also, people shouldn’t fear that their habit will dissolve if they don’t practice it daily.

“If you lapse once or twice, you’re not ruined,” Professor Wood said. “That’s a misconception.”

And that leads to …

MYTH 7 Shame and guilt keep you on track.

No. People need to be kinder to themselves, showing self-compassion if they lapse, Ms. Rubin said. But it’s a fine balance between treating yourself kindly and making endless rationalizations and excuses.

“I might mindfully make an exception,” she said, such as choosing to eat a traditional Christmas cake every year. “But I’m not making excuses in the moment: I’ll hurt the hostesses’ feelings. You only live once. It’s the holidays.”

One last piece of advice: If you want to be in better shape, get a dog. Professor Wood said studies show dog owners have lower body mass indexes. But here’s the catch: That’s only true if you walk the animal.

Drug addiction is complex

Addiction, research

We’re told studies have proven that drugs like heroin and cocaine instantly hook a user. But it isn’t that simple – little-known experiments over 30 years ago tell a very different tale.

Drugs are scary. The words “heroin” and “cocaine” make people flinch. It’s not just the associations with crime and harmful health effects, but also the notion that these substances can undermine the identities of those who take them. One try, we’re told, is enough to get us hooked. This, it would seem, is confirmed by animal experiments. 0312ILIN03-web.jpg

Many studies have shown rats and monkeys will neglect food and drink in favour of pressing levers to obtain morphine (the lab form of heroin). With the right experimental set up, some rats will self-administer drugs until they die. At first glance it looks like a simple case of the laboratory animals losing control of their actions to the drugs they need. It’s easy to see in this a frightening scientific fable about the power of these drugs to rob us of our free will.

But there is more to the real scientific story, even if it isn’t widely talked about. The results of a set of little-known experiments carried out more than 30 years ago paint a very different picture, and illustrate how easy it is for neuroscience to be twisted to pander to popular anxieties. The vital missing evidence is a series of studies carried out in the late 1970s in what has become known as “Rat Park”. Canadian psychologist Bruce Alexander, at the Simon Fraser University in British Columbia, Canada, suspected that the preference of rats to morphine over water in previous experiments might be affected by their housing conditions.

To test his hypothesis he built an enclosure measuring 95 square feet (8.8 square metres) for a colony of rats of both sexes. Not only was this around 200 times the area of standard rodent cages, but Rat Park had decorated walls, running wheels and nesting areas. Inhabitants had access to a plentiful supply of food, perhaps most importantly the rats lived in it together.

Rats are smart, social creatures. Living in a small cage on their own is a form of sensory deprivation. Rat Park was what neuroscientists would call an enriched environment, or – if you prefer to look at it this way – a non-deprived one. In Alexander’s tests, rats reared in cages drank as much as 20 times more morphine than those brought up in Rat Park. 

Inhabitants of Rat Park could be induced to drink more of the morphine if it was mixed with sugar, but a control experiment suggested that this was because they liked the sugar, rather than because the sugar allowed them to ignore the bitter taste of the morphine long enough to get addicted. When naloxone, which blocks the effects of morphine, was added to the morphine-sugar mix, the rats’ consumption didn’t drop. In fact, their consumption increased, suggesting they were actively trying to avoid the effects of morphine, but would put up with it in order to get sugar.

‘Woefully incomplete’

The results are catastrophic for the simplistic idea that one use of a drug inevitably hooks the user by rewiring their brain. When Alexander’s rats were given something better to do than sit in a bare cage they turned their noses up at morphine because they preferred playing with their friends and exploring their surroundings to getting high.

Further support for his emphasis on living conditions came from another set of tests his team carried out in which rats brought up in ordinary cages were forced to consume morphine for 57 days in a row. If anything should create the conditions for chemical rewiring of their brains, this should be it. But once these rats were moved to Rat Park they chose water over morphine when given the choice, although they did exhibit some minor withdrawal symptoms.

You can read more about Rat Park in the original scientific report. A good summary is in this comic by Stuart McMillen. The results aren’t widely cited in the scientific literature, and the studies were discontinued after a few years because they couldn’t attract funding. There have been criticisms of the study’s design and the few attempts that have been made to replicate the results have been mixed.

Nonetheless the research does demonstrate that the standard “exposure model” of addiction is woefully incomplete. It takes far more than the simple experience of a drug – even drugs as powerful as cocaine and heroin – to make you an addict. The alternatives you have to drug use, which will be influenced by your social and physical environment, play important roles as well as the brute pleasure delivered via the chemical assault on your reward circuits

It suggests that even addictions can be thought of using the same theories we use to think about other choices, there isn’t a special exception for drug-related choices. Rat Park also suggests that when stories about the effects of drugs on the brain are promoted to the neglect of the discussion of the personal and social contexts of addiction, science is servicing our collective anxieties rather than informing us
