Cannabis Users Who Consume Multiple Forms More Likely to Develop Addiction Disorder

A new study has shed light on a potential warning sign for cannabis addiction, revealing that people who consume cannabis in multiple forms are more likely to use it heavily or develop an addiction.

Researchers at NYU Langone Health analyzed data from a national survey and identified four distinct patterns of cannabis consumption among US adults. The findings show that while smoking remains the most popular method, approximately one in seven users consumes cannabis in nearly every available form.

Cannabis is consumed through various methods, including smoking, vaping, eating edibles, and dabbing, which involves heating concentrated products and inhaling the resulting vapor. Its use has become widespread across the United States, with recent national survey figures indicating that over 15 percent of Americans aged 12 and older had used cannabis within the previous 30 days.

The researchers identified four consumption patterns: those who primarily smoked cannabis (48%), those who combined smoking and vaping (21%), those who mainly consumed edibles (17%), and a "polymodal group" that used cannabis in almost every available form (14%).

The study's findings also revealed significant disparities in the prevalence of cannabis use disorder among individuals who used multiple forms of cannabis compared to those who used a single method. A staggering 67 percent of polymodal users met the criteria for the disorder, more than double the rate of those who primarily smoked and vaped, at 47 percent.

This stark contrast suggests that using cannabis in multiple ways may be an indicator of heavier use and addiction symptoms. According to study lead author Omar El-Shahawy, clinicians could benefit from asking patients not only about their cannabis use but also how they consume it, as this information can help identify those who require a more thorough assessment.

The researchers analyzed responses from 17,732 adults who had used cannabis in the past month, drawing data from the 2022-2023 National Survey on Drug Use and Health. By applying statistical methods to identify patterns in consumption habits, they conducted the first national analysis of how different cannabis use methods naturally cluster together.

Younger adults were disproportionately represented among those who used multiple forms of cannabis, with nearly one-third of both the smoking and vaping group and the polymodal group falling within the 18-25 age range. In contrast, only about one-sixth of participants who primarily smoked cannabis belonged to this age demographic.

Notably, younger adults are more likely to use multiple methods of cannabis consumption, which may indicate a higher risk of developing cannabis use disorder. This disparity highlights the importance of considering not just the frequency but also the method of cannabis use when assessing addiction risks and developing targeted interventions.

The study's findings also reveal a distinct demographic pattern when it comes to consuming edible cannabis products. Women made up more than half of those who mainly used edibles, and this method was notably prevalent among college graduates. However, the researchers did not investigate why participants chose specific consumption methods.

Another concern arises from the relationship between smoking cannabis and tobacco use. People who smoked cannabis were significantly more likely to also smoke cigarettes compared to those who primarily vaped or consumed edible products. This is worrisome because both cannabis and tobacco smoking involve combustion, potentially exposing lungs to additional hazardous chemicals.

According to Dr. Joseph J. Palamar, a professor at NYU Grossman School of Medicine, the strong connection between smoking cannabis and cigarettes poses a significant health risk. By regularly inhaling smoke from both substances, individuals may be exposing their lungs to an even broader range of toxic compounds.

The study's implications suggest that public health education should adapt to account for diverse cannabis consumption methods. Rather than focusing primarily on the risks associated with smoking, messages should acknowledge and address the distinct patterns emerging among different groups. This could involve tailoring prevention efforts to specific demographics.

The findings also underscore the need to reassess traditional prevention approaches in light of these changing consumption patterns. As younger adults and those combining multiple methods may be at increased risk, targeted interventions are essential to mitigate potential harm.

The way people consume cannabis is becoming increasingly diverse, with many using it in ways beyond smoking. This shift has important implications for public health messaging, which must adapt to address these new patterns of use. For younger adults, this means being aware of the potential risks associated with vaping and combining multiple forms of cannabis.

Researchers are eager to explore the motivations behind different consumption patterns, particularly among those who prefer edibles. One key question is whether individuals who opt for edibles are more likely to use cannabis as a way to manage specific issues like pain or sleep disturbances. This could have significant implications for how health professionals approach patient care.

The study has some limitations that must be acknowledged. Participants' self-reported cannabis habits may not always reflect the full picture, and some may have underreported their consumption. Additionally, while the research establishes an association between certain consumption patterns and an increased risk of cannabis use disorder, it does not prove causation.

Further investigation is needed to fully understand the relationship between these factors. The study's findings highlight the need for targeted interventions that take into account the diverse ways people use cannabis. By doing so, health professionals can better mitigate potential harm and provide more effective support for those at risk.

The research was funded by a grant from the National Institutes of Health, which provided crucial support for this project. A team of researchers from NYU Langone contributed to the study, alongside a co-investigator from the University of California, San Diego.

Researchers have made an unexpected discovery related to cannabis use, identifying a potential warning sign for addiction. This finding may help medical professionals and individuals recognize early indicators of dependence on cannabis.

The study highlights the importance of monitoring changes in sleep patterns as a potential indicator of cannabis use disorder. A significant correlation was found between disrupted sleep and increased risk of cannabis addiction. Further research is needed to confirm these findings and explore their implications for prevention and treatment strategies.
