High-potency marijuana concentrates on today’s legal markets can contain upwards of 90 percent THC, so one might reasonably expect them to pack a greater psychoactive punch than typical flower, which tops out around 30 percent.
But that may not be the case, according to a new study out of the University of Colorado at Boulder.
Researchers found that while THC blood levels spiked after users consumed concentrates, impairment levels didn’t significantly differ from participants who used flower.
“Surprisingly, we found that potency did not track with intoxication levels,” said lead author Cinnamon Bidwell, an assistant professor in CU’s Institute of Cognitive Science. “While we saw striking differences in blood levels between the two groups, they were similarly impaired.”
The study, published Wednesday in JAMA Psychiatry, involved 121 Colorado adults who were regular marijuana consumers. Participants were randomly assigned to consume either relatively low-THC marijuana flower, which ranged from 16-24 percent THC, or higher-potency concentrates, which ranged from 70-90 percent. At various points, researchers tested participants’ blood plasma THC levels, surveyed their mood and subjected them to an array of neurobehavioral tasks meant to test attention, memory, inhibitory control and balance.
Researchers used a mobile pharmacology lab they dubbed the “cannavan” to study participants’ cannabis while complying with federal law, the University of Colorado said.
“Most neurobehavioral measures were not altered by short-term cannabis consumption,” the study found. “However, delayed verbal memory and balance function were impaired after use. Differing outcomes for the type of product (flower vs concentrate) or potency within products were not observed.” Impairment faded after about an hour.
“Despite differences in THC exposure, flower and concentrate users showed similar neurobehavioral patterns after acute cannabis use.”
A University of Colorado at Boulder press release calls the paper “the first to assess the acute impact of cannabis among real-world users of legal market products” and says the findings “could inform everything from roadside sobriety tests to decisions about personal recreational or medicinal use.”
Lawmakers and police departments who assume higher THC blood levels correlate with greater impairment, for example, may need to re-educate themselves on how to measure impaired driving. Consumers hoping that high-THC products will mean more mind-blowing highs, on the other hand, may ultimately be putting that extra THC—and the money spent on it—to waste.
“It raises a lot of questions about how quickly the body builds up tolerance to cannabis and whether people might be able to achieve desired results at lower doses,” Bidwell said.
As more states have opened legal marijuana markets, high-potency concentrates have become more widely available. Critics of marijuana legalization, as well as some health experts, have worried that those products could unleash health hazards on both individual users and broader society. While the University of Colorado paper doesn’t answer questions about potential long-term side effects of THC exposure, its findings indicate short-term impacts of concentrates don’t necessarily warrant additional concern.
“People in the high concentration group were much less compromised than we thought they were going to be,” said co-author Kent Hutchison, a professor of psychology and neuroscience at CU Boulder who also studies alcohol addiction. “If we gave people that high a concentration of alcohol it would have been a different story.”
One reason that higher THC blood levels didn’t translate to higher highs could be that the body’s finite number of cannabinoid receptors, which THC molecules bind to, become saturated regardless of whether higher- or lower-THC products are used. Any excess THC in consumers’ blood plasma, in that case, would be metabolized and not contribute to further impairment.
“Cannabinoid receptors may become saturated with THC at higher levels,” the study says, “beyond which there is a diminishing effect of THC.”
That’s not to forget the “striking differences in blood levels” the study observed between the two groups of participants. Researchers cautioned that while short-term effects of higher-potency cannabis consumption don’t seem to differ much from more traditional methods, we still don’t know much about how elevated cannabinoid levels affect health over time.
“Does long-term, concentrated exposure mess with your cannabinoid receptors in a way that could have long-term repercussions?” asked Hutchison. “Does it make it harder to quit when you want to? We just don’t know yet.”
The controversy—and uncertainty—around how cannabis affects driver safety has long been a sticking point for legalization. And given the ongoing difficulty in associating THC levels with impairment, it’s unlikely to be resolved anytime soon.
As legalization spreads, however, more and more studies are examining marijuana-related impairment. A study published last year found that drivers who tested at the legal limit in many states (2-5 nanograms THC per milliliter of blood) were statistically no more likely to cause a crash than people who had not consumed cannabis, concluding that “the impact of cannabis on road safety is relatively small at present time.”
Earlier this month, Democratic leadership in a House committee introduced a bill that would require states with legal cannabis programs to consider creating programs “to educate drivers on the risks associated with marijuana-impaired driving and to reduce injuries and deaths resulting from individuals driving motor vehicles while impaired by marijuana.”
A congressional report from a year earlier, however, suggested that much of the alarmism about cannabis-impaired driving was unfounded.
“Although laboratory studies have shown that marijuana consumption can affect a person’s response times and motor performance,” the Congressional Research Service wrote, “studies of the impact of marijuana consumption on a driver’s risk of being involved in a crash have produced conflicting results, with some studies finding little or no increased risk of a crash from marijuana usage.”
Banking Activity Increases In States That Legalize Marijuana, Study Finds
While marijuana businesses often struggle to find banks that are willing to take them on as clients due to risks caused by the ongoing federal prohibition of cannabis, a new study found that banking activity actually increases in states that legalize marijuana.
The research doesn’t make a direct connection between state-level marijuana reform and the increased activity, but it does strongly imply that there’s a relationship—even if the factors behind the trend aren’t exactly clear.
Researchers set out to investigate banking trends in states that have legalized cannabis, looking at bank regulatory filings with the Federal Deposit Insurance Corporation (FDIC) from 2011 to 2016. They found evidence that “banking activity (deposits and subsequent loans) increase considerably in legalizing states relative to non-legalizing states.”
That’s in spite of the fact that banks and credit unions run the risk of being penalized by federal regulators for working with businesses that deal with a federally controlled substance.
“While uncertainty can result in overly cautious behavior and hinder economic activity, we do not find evidence of this with cannabis laws and the banking industry,” the authors wrote in the new paper—titled, “THC and the FDIC: Implications of Cannabis Legalization for the Banking System.”
The study analyzed data from “150,566 bank-quarter observations from 6,932 unique banks located in 46 different states.” It found that deposits increased by an average range of 3.14-4.33 percent—and bank lending increased by 6.54-8.62 percent—post-legalization.
“Our results indicate that deposits and loans increased for banks after recreational cannabis legalization.”
Of course, it makes sense that legal states would see increased financial activity in the banking sector after opening a new market, even if only some banks choose to take the risk of working directly with cannabis businesses. The emerging marijuana industry also supports an array of ancillary firms and traditional companies that provide services to dispensaries and grow operations.
As of June 30, there were 706 financial institutions that had filed requisite reports saying they were actively serving cannabis clients. Thats up from 689 in the previous quarter but still down from a peak of 747 in late 2019.
But the question remains: why are some banks deciding to take on marijuana clients while others remain wary of federal repercussions?
The study authors—from the University of Arizona, Drexel University, San Diego State University and Scripps College—put forward two possibilities about why “the risk from regulatory uncertainty did not decrease banks’ willingness to accept deposits or make loans.”
The increase “may suggest that banks were either unconcerned about the potential risk associated with accepting cannabis related deposits or optimistic about the chances that regulations will adapt to the needs of legalizing states,” the paper reasons.
Confidence about working with a federally illegal industry may well have been bolstered in 2014 when the Financial Crimes Enforcement Network (FinCEN) under the Obama administration issued guidance to financial institutions on reporting requirements for cannabis-related businesses.
The second option, optimism about federal reform, also seems possible. It was around the time that the bipartisan Secure and Fair Enforcement (SAFE) Banking Act was first introduced that there was a notable spike in financial institutions reporting that they have marijuana business clients.
In the years since, that legislation has been approved in some form five times in the U.S. House of Representatives, but it’s continued to stall in the Senate. In general, banks reporting marijuana accounts has remained relatively stable since 2019.
“Although many have speculated about the increased legal risks to banks, there is a lack of evidence for instances where banks are criminally prosecuted or lose their federally insured status,” the study states. “If these negative repercussions rarely happen, it makes sense that banks would not respond to the legislative uncertainty.”
“As more state regulators issue statements in support of banks and credit unions serving the cannabis industry, the financial institutions can become more optimistic about the chances that regulations will adapt in their favor with time,” the authors wrote.
Despite optimism for future reform that certain lawmakers have expressed, it doesn’t necessarily take the sting out of the latest failed attempt to secure protections for banks that choose to work with state-legal cannabis businesses as part of a large-scale defense bill.
A pro-reform Republican senator recently slammed Democrats for failing to advance marijuana banking reform despite having a congressional majority and control of the presidency.
For what it’s worth, the secretary of the U.S. Treasury Department recently said that freeing up banks to work with state-legal marijuana businesses would “of course” make the Internal Revenue Service’s (IRS) job of collecting taxes easier.
With respect to the SAFE Banking Act, a bipartisan coalition of two dozen governors recently implored congressional leaders to finally enact marijuana banking reform through the large-scale defense legislation.
A group of small marijuana business owners also recently made the case that the incremental banking policy change could actually help support social equity efforts.
Rodney Hood, a board member of the National Credit Union Administration, wrote in a recent Marijuana Moment op-ed that legalization is an inevitability—and it makes the most sense for government agencies to get ahead of the policy change to resolve banking complications now.
Young People Who Use Marijuana Have Better Orgasms and Sexual Function, Study Says
Young people who smoke marijuana and drink alcohol have better orgasms and overall sexual function than their peers who abstain or use less, a study in Spain recently concluded.
Because the existing scientific literature on the impact of drinking and drug use on sexual functioning is contradictory—finding both benefits and harms—a team of researchers from the University of Almeria designed the new observational study to analyze their affect with three commonly used surveys to detect potential risky drinking and cannabis use, as well as changes to one’s sexual functioning.
“Sexual function in young people who use cannabis and alcohol more frequently was shown to be better than in those who do not use either.”
From January to June 2020, researchers assessed 185 females and 89 males between the ages of 18 and 30 who were either regular cannabis or alcohol users or non-users, excluding those who used other substances like opiates or MDMA, as well as screening out those with pre-existing conditions like depression and diabetes, which could have a negative impact on their sexual performance.
“Sexual function is improved in young people who are high-risk cannabis consumers with a moderate risk of alcohol use, resulting in increased desire, arousal, and orgasm,” the study, published at the end of last month in the Journal Healthcare, found. “This improvement is usually associated with a reduction in anxiety and shame, which facilitates sexual relationships.”
The cannabis users scored higher than non-users on both the overall sexual functioning scale and the subscales of arousal and orgasm. And those who used cannabis the most were found to report higher sexual functioning and arousal scores than the moderate users. No differences were found on the desire and orgasm subscales between moderate and heavy users and no differences were detected amongst men and women respondents to the survey.
“Our findings indicate that young people who use cannabis frequently, regardless of gender, have better overall sexual function.”
When it comes to alcohol use, no significant differences in either overall sexual function or in any of the subscales measured, were found between drinking and non-drinking participants. However, there were statistically significant differences based on levels of alcohol consumption, potentially suggesting some dose dependent outcomes.
Those who reported heavy drinking scored higher on the total sexual function questionnaire and the arousal subscale than those who did not drink at all, the study found. And the high consumption participants had significantly higher total questionnaire and orgasm subscale scores than the moderate consumption participants. But those participants who reported an existing alcohol dependence had significantly lower scores than their peers whose drinking was evaluated to be merely at a higher risk for dependency.
These marijuana results are consistent with previous studies that found cannabis use enhances sex and masturbation, increases sexual desire and leads to better orgasms, as well as those that have found cannabis consumers have more sex than cannabis abstainers, and a higher score on sexual health inventories and serum testosterone levels.
“The findings of this study revealed a higher score in sexual function, as well as arousal and orgasm, in subjects at risk of having cannabis-related problems and risk of addiction associated with alcohol consumption.”
Older studies that previously found some evidence of erectile dysfunction among heavier alcohol consumers may have been influenced by the older ages of the respondents, according to the research team behind the new paper, which focused on individuals in their late teens and 20s, “where erectile dysfunction is less common.”
Questions remain about the different types of sexual relationships (long-term vs sporadic vs unstable) that frequent consumers engage in or if there is any correlation between use and relationship type.
The research team also cautioned that this study did not capture any potential medium range and longer-term consequences of heavier drinking and cannabis use, including any potential proclivity to engage in less safe sex practices due to inebriation.
Since the increased desire, arousal, and orgasms in young people who are high-risk cannabis consumers with a moderate risk of alcohol use, is usually associated with a reduction in anxiety and shame, which facilitates sexual relationships, the study called for future sex education practices to focus on strategies that reduce shame and anxiety, to prevent young people from developing potential drug and alcohol dependency issues later on in their lives.

One-Third Of Programmers Use Marijuana While Working, With Many Touting Creative Benefits, Study Finds
More than one-third of software programmers say they’ve used marijuana while working, with many finding that it helps promote creativity and get them into the “programming zone,” according to a new study.
Researchers at the University of Michigan said that anecdotal evidence suggested that those in programming were more likely to use cannabis on the job, so they set out to conduct the “first large-scale survey” on the topic, asking 803 developers to detail how marijuana comes into play in their work.
A main motivation for the study was the fact that drug testing policies remain common in the programming sector, which may be contributing to “hiring shortages for certain jobs.”
That’s even the case at the federal level, the study authors note, citing comments by former FBI Director James Comey, who said in 2014 that he was interested in loosening employment policies around cannabis because some prospective agents “want to smoke weed on the way to the interview.”
2) The main motivations for using cannabis while programming are related to enjoyment or perceived programming enhancement. Wellness-related motivations (e.g., mental health or chronic pain) are less common. (3/6)

“This prohibition of cannabis use in software engineering has contributed to a widely-reported hiring shortage for certain US government programming jobs,” the study says.
All told, 35 percent of survey participants said that they’ve “tried cannabis while programming or completing another software engineering-related task.” Seventy-three percent of that group said they’ve consumed marijuana while working in the past year.
The study—titled “Hashing It Out: A Survey of Programmers’ Cannabis Usage, Perception, and Motivation” and published this month in Cornell University’s arXiv—also looked at frequency of use among those who said they’ve used marijuana while engineering.
Fifty-three percent said they’ve consumed cannabis while programming at least 12 times, 27 percent said they used it at least twice a week and four percent said they use it while working on a nearly daily basis.
The study authors wanted to get a better understanding of why programmers chose to consume marijuana, too. And they found that the most common tasks that people used marijuana for were brainstorming, prototyping, coding and testing.
“Overall, we found that programmers were more likely to report enjoyment or programming enhancement motivations than wellness motivations: the most common reasons were ‘to make programming-related tasks more enjoyable’ (61%) and ‘to think of more creative programming solutions’ (53%),” the study found. “In fact, all programming enhancement reasons were selected by at least 30% of respondents. On the other hand, general wellness related reasons (such as mitigating pain and anxiety) were all cited by less than 30% of respondents. Thus, while wellness does motivate some cannabis use while programming, it is not the most common motivation.”
4) Software managers disapprove of cannabis use less than employees think they do 🙂 (5/6)

While there’s a notable prevalence of cannabis consumption among programmers, even most of those who don’t use marijuana are supportive of reform, the study found.
“Ninety-one percent of our participants say that marijuana use should be legal for both recreational and medicinal use compared to 60 percent of the general United States population in 2021,” the authors wrote.
The study also found that “cannabis use while programming occurs at similar rates for programming employees, managers and students despite differences in cannabis perceptions and visibility.”
“Our results have implications for programming job drug policies and motivate future research into cannabis use while programming,” the study states.
Drug testing policies have become a hot topic as more states enact legalization.
After New York opted to end prohibition this year, for example, the state Department of Labor announced that most employers are no longer allowed to drug test most workers for cannabis.
Amazon recently said that its earlier decision to end drug testing for cannabis will also be retroactive, meaning former workers and applicants who were punished for testing positive for THC will have their employment eligibility restored.
Lawmakers in the Senate and House have both included language in recent appropriations reports urging a review of employment policies for federal agencies with respect to personal use of cannabis. The House version passed in July, while the Senate Democrats’ report was released in October.
The Office of Personnel Management (OPM) issued a memo to federal agencies this year that says admitting to past marijuana use should not automatically disqualify people from being employed in the federal government.
Meanwhile, the Biden administration came under criticism after it was reported that it had fired or otherwise punished dozens of staffers who admitted to prior marijuana use. That came after the White House instituted a policy of granting waivers to some staff who’ve used cannabis.
Press Secretary Jen Psaki subsequently said that nobody in the White House was fired for “marijuana usage from years ago,” nor has anyone been terminated “due to casual or infrequent use during the prior 12 months.” However, she’s consistently declined to speak to the extent to which staff have been suspended or placed in a remote work program because they were honest about their history with marijuana on a federal form that’s part of the background check process.
