THC levels not correlated with driver impairment: study

The presence of THC in blood is not a consistent predictor of either driver performance or impairment, according to the conclusions of a new Congressional Research Service report assessing cannabis and psychomotor performance.

The report acknowledges: “Research studies have been unable to consistently correlate levels of marijuana consumption, or THC in a person’s body, and levels of impairment. Thus, some researchers, and the National Highway Traffic Safety Administration, have observed that using a measure of THC as evidence of a driver’s impairment is not supported by scientific evidence to date.”

It further reports that data is “conflicting” with regard to whether marijuana usage plays a substantial role in traffic accidents, noting, “Levels of impairment that can be identified in laboratory settings may not have a significant impact in real world settings, where many variables affect the likelihood of a crash occurring.”

It concludes: “There is as yet no scientifically demonstrated correlation between levels of THC and degrees of impairment of driver performance, and epidemiological studies disagree as to whether marijuana use by a driver results in increased crash risk. … Based on current knowledge and enforcement capabilities, it is not possible to articulate a similarly simple level or rate of marijuana consumption and a corresponding effect on driving ability.”

The findings are consistent with prior studies by the National Highway Traffic Safety Administration and others reporting that the presence of THC in blood, particularly at low levels, is not consistently correlated with either psychomotor impairment or crash culpability.

Six states – Illinois, Montana, Nevada, Ohio, Pennsylvania, and Washington impose various per se limits for the presence of specific amounts of THC in blood while 12 states (Arizona, Delaware, Georgia, Illinois, Indiana, Iowa, Michigan, Oklahoma, Rhode Island, South Dakota Utah, and Wisconsin) impose zero tolerant per se standards. In those states, it is a criminal violation of the traffic safety laws to operate a motor vehicle with any detectable levels of THC in blood. Colorado law infers driver impairment in instances where THC is detected in blood at levels of 5ng/ml or higher.

Veterans substituting cannabis for alcohol, drugs

PALO ALTO, Calif. — Military veterans who participate in a state’s medical marijuana access program frequently substitute cannabis for alcohol and other controlled substances, according to data published in The American Journal of Drug and Alcohol Abuse.

A team of investigators from Palo Alto University in California, Harvard University, and the Perelman School of Medicine in Philadelphia surveyed marijuana use patterns in 93 U.S. military veterans participating in a medical cannabis collective.

Nearly 80 percent of respondents reported using cannabis “to treat both physical and mental health symptoms.” Respondents were most likely to report consuming cannabis therapeutically to mitigate symptoms of chronic pain (69 percent), anxiety (66 percent), post-traumatic stress (59 percent), and depression (56 percent).

More than 60 percent of respondents said that they consumed cannabis as a substitute for other illicit or licit substances, particularly alcohol. Nearly half of all respondents said that they use medical cannabis in place of other prescription medications.

Authors concluded, “The current study also confirms the findings of previous studies that have documented a trend in substitution behavior, where cannabis is substituted for other drugs, which, if associated with reduced harm, could be beneficial for overall health.”

Nevada bars employers from bias against cannabis users

CARSON CITY, Nev. — Democratic Gov. Steve Sisolak has signed legislation into law prohibiting certain employers from refusing to hire workers because they tested positive for cannabis on a pre-employment drug screen. The new law takes effect on Jan. 1, 2020.

Assembly Bill 132 makes it “unlawful for any employer in [Nevada] to fail or refuse to hire a prospective employee because the prospective employee submitted to a screening test and the results of the screening test indicate the presence of marijuana.”

The law is not applicable to prospective employees seeking certain safety sensitive positions, such as those seeking employment as firefighters, emergency medical technicians, or federally licensed drivers.

“This is a victory for both cannabis consumers and Nevada’s economy,” said Nevada NORML Director Madisen Saglibene. “Just as someone would not lose their job on a Monday for a cocktail they consumed the previous Friday, it is critical to protect the rights and dignity of individuals who choose to enjoy marijuana.”

Earlier this year, New York City lawmakers enacted municipal legislation barring non-safety sensitive employers from administering marijuana drug tests to prospective employees.

Urinalysis drug screening, which is most commonly utilized by employers, detects the presence of inactive marijuana metabolites (breakdown products). The residual presence of these compounds may be detectable in urine for several weeks or even months following cannabis abstinence.

The governor also signed legislation into law this session facilitating the expungement of prior marijuana convictions, expanding the state’s medical cannabis access program, prohibiting the courts from denying child custody or visitation solely based upon a parent’s medical marijuana patient status, and encouraging banking institutions to work with licensed marijuana businesses and to process financial transactions.

LGBTQ people, weed, and mental health: what you need to know

Community uses marijuana at much higher rates than general population

Published

Uncloseted Media published this story on May 7.

By SPENCER MACNAUGHTON | In 2025, the global cannabis market size was valued at nearly $103 billion. By 2034, that number is expected to explode by roughly 1,400 percent to more than $1.43 trillion.

In short, as an increasing number of countries legalize marijuana use, everyone is starting to consume a lot more weed. And LGBTQ people tend to use cannabis at much higher rates than the general population. One study found that 55 percent of lesbian and 45 percent of gay young adults use marijuana, compared to about 33 percent and 37 percent, respectively, of their straight counterparts.

As LGBTQ people face a mental health crisis, the mainstream stereotypes that depict weed as an antidote for anxiety, panic and depression aren’t painting the full picture. And that could be exacerbating the mental health struggles so many queer people, and especially youth, face.

Here’s what the research demonstrates about marijuana and its effects on mental health:

  • Multiple studies suggest a link between marijuana use and an increased risk of mental health disorders, including schizophrenia, depression and anxiety in individuals who are genetically predisposed.
  • One study found that daily marijuana use, especially among younger people, makes some individuals seven times more likely to develop psychosis.

The increase in higher-potency strains of marijuana could pose unknown risks. In 1995, the average content of Tetrahydrocannabinol (THC) in confiscated marijuana was less than 4 percent. In 2022, it was more than 16 percent. Researchers don’t know the full extent of the impact that these higher concentrations can have on mental health and especially on younger people whose brains are still developing.

  • systematic review of studies published between 2013 and 2025 found damning results for the mental health of young cannabis users:

They were 51 percent more likely to experience depression, 58 percent more likely to experience anxiety, between 50 and 65 percent more likely to experience suicidal ideation and 80 to 87 percent more likely to have attempted suicide.

  • While the above stats paint a grim picture, there is also some research that suggests benefits of cannabis use:
    • A 2025 systematic review found that “medicinal” weed showed some efficacy in relieving withdrawal symptoms of opioid use disorder. THC use has been associated with improvement of post-traumatic stress disorder symptoms, bipolar symptoms and sleep quality.
    • Other studies found that THC administered in a controlled setting was associated with a decrease of symptoms and adverse effects for a range of mental health disorders, including schizophrenia, psychotic symptoms, and anorexia nervosa.

Beyond what we pulled from academia, there is an astounding lack of information about the interplay between weed and mental health. As we dive deeper into Mental Health Awareness Month, I hope advocacy organizations, influencers and news outlets ramp up their coverage of this important topic that affects the countless LGBTQ weed smokers, many of whom are already struggling.

New Mexico guv signs marijuana legalization

Retail sales would begin by April 2022

decriminalizing possession, gay news, Washington Blade

Democratic Gov. Michelle Lujan Grisham earlier this month signed two separate measures into law amending the state’s marijuana policies. The first measure (House Bill 2) legalizes and regulates marijuana possession, production, and sales for adults. The second measure (Senate Bill 2) facilitates the automatic review and expungement of the records of those convicted of low-level marijuana offenses.

Lawmakers approved both bills during a special legislative session demanded by Gov. Lujan Grisham, who had been a vocal proponent of the reforms.

NORML State Policies Manager Carly Wolf said: “This is a day to celebrate! New Mexico will greatly benefit from this new revenue stream and the creation of thousands of jobs. Most notably though, legalization will spare thousands of otherwise law-abiding residents from arrest and a criminal record, and the state’s new expungement law will help provide relief to many who are suffering from the stigma and other collateral consequences associated with a prior marijuana conviction.”

The adult-use measure (House Bill 2) permits those ages 21 and older to legally purchase up to two ounces of marijuana and/or up to 16 grams of cannabis extract from licensed retailers. It also permits adults to home-cultivate up to six mature plants for their own personal use. Retail sales would begin by April 2022.

The expungement measure (Senate Bill 2) stipulates that those with past convictions for offenses made legal under this act are eligible for automatic expungement of their records. Those currently incarcerated for such offenses are eligible for a dismissal of their sentence. It’s estimated that over 150,000 New Mexico residents are eligible for automatic expungement under this measure, according to the Department of Public Safety.

Delaware cannabis activists take on corporate marijuana

Criticism from medical marijuana operators claimed that HB150 offers too many cultivation and retail licenses

cannabis regulation, gay news, Washington Blade

As the country moves forward with sweeping changes in cannabis policy reform, locals in Delaware are tangling with corporate, multi-state medical marijuana permit holders to pass a bill for full legalization.

Adult-use activists and registered medical patients were stunned to hear opposing testimony from Delaware’s medical marijuana operators. Patients already deal with limited access and costly products. Now, many see the established industry voicing opposition as simply obstructing the progress of adult-use legislation. In response, some patients are now staging a boycott of the regulated dispensaries.

During the first committee hearing for HB150, Delaware’s adult-use bill, four of the state’s six currently licensed, multi-million dollar medical cannabis facilities offered negative testimony.

Zoë Patchell, executive director of Delaware CAN responded: “This market belongs to the long-time consumers, patients, and activists. We create the demand, we’ve been the ones driving the reform efforts, and we pay the prices at dispensaries. Cannabis is more than a market – cannabis is a community. These companies cannot reasonably fathom that we are going to purchase cannabis from any entity that has proven to put profits over patients. And now they seem willing to put consumers’ lives and freedom at risk just to hold out for an unfair advantage in the industry.”

These included publicly traded Columbia Care, “Fresh Delaware” aka CCRI, CannTech Research Inc., and the owner of EZY Venture aka “The Farm.”

They all went on record condemning HB150, and pushing a false narrative about oversupply. The core demand from the permit cartel was some protection for their private business interests with guaranteed adult-use licenses.
Criticism from the medical marijuana operators claimed that HB150 offers too many new cultivation and retail licenses, underlined by deep yet unfounded fears that the new competition would put their companies out of business.

Patchell noted, “We are not going to sit back while multi-state corporate entities, that already monopolize East Coast medical markets, work to undermine our social equity and micro-license provisions.”
