Examining prevalence and correlates of cigarette and marijuana co-use among young adults using ten years of NHANES data.

Prior research has documented a strong association between cigarette and marijuana use among young adults; it is critical to study patterns and risk factors for co-use.

Beliefs and attitudes regarding prenatal marijuana use: Perspectives of pregnant women who report use.

With the increasingly permissive legal and social environments regarding marijuana, it is important to understand prenatal marijuana use from the perspective of women who use marijuana. Our objective was to qualitatively describe the marijuana use experiences, beliefs, and attitudes of women who used marijuana during pregnancy.

Marijuana use motives mediate the association between experiences of childhood abuse and marijuana use outcomes among emerging adults.

Experiences of childhood sexual abuse (CSA) and childhood physical abuse (CPA) are associated with poor mental health outcomes including substance use in subsequent years. Marijuana use motives (i.e., coping with negative affect, enhancing positive affect, or improving social interactions) may influence problematic substance use among young adults. Specifically, motives may be associated with severity of marijuana use outcomes among individuals who have experienced CSA or CPA. This study investigated the in...

Is marijuana use associated with lower inflammation? Results from waves III and IV of the national longitudinal study of adolescent to adult health.

Some research suggests that marijuana use facilitates an anti-inflammatory response, yet the relationship between marijuana use and inflammation, as measured by C-reactive protein (CRP), remains poorly understood. The present study examined the association between recency of marijuana use and serum C-reactive protein levels in a nationally representative sample of adults.

Heterogeneous Patterns of Marijuana Use Motives Using Latent Profile Analysis.

Given that marijuana use is often associated with detrimental physical and mental health problems, research examining motives for its use is critical for effective remedial and preventive treatment. To date, the majority of research on marijuana use motives has used variable-centered analyses, which overlooks potentially meaningful heterogeneous response patterns and the associations of those patterns with other risk/protective factors.

Association of US Medical Marijuana Laws With Nonmedical Prescription Opioid Use and Prescription Opioid Use Disorder.

Between 1997 and 2017, the United States saw increases in nonmedical prescription opioid use and its consequences, as well as changes in marijuana policies. Ecological-level research hypothesized that medical marijuana legalization may reduce prescription opioid use by allowing medical marijuana as an alternative.

An examination of consequences among college student drinkers on occasions involving alcohol-only, marijuana-only, or combined alcohol and marijuana use.

This event-level study examined within-person differences in consequences for college students who engaged in alcohol-only, marijuana-only, or simultaneous alcohol and marijuana (SAM) use across 18 weekend days. Participants ( = 451) were asked to report consequences they experienced on each occasion across five different types of events: (a) heavier alcohol combined with marijuana; (b) lighter alcohol combined with marijuana; (c) heavier alcohol only; (d) lighter alcohol only; and (e) marijuana only. Occas...

To burn or retain crop residues on croplands? An integrated analysis of crop residue management in China.

Crop residue burning influences human health and global climate change. In China-the world's largest crop residue producer-farmers burn almost one quarter of their crop residues in the field after harvest, despite the government providing financial incentives such as subsidies to retain crop residues. This study combined economic analyses with simulations of soil carbon accumulation and carbon emission reduction associated with different residue management practices to determine the minimum level of incenti...

Investigating how perceived risk and availability of marijuana relate to marijuana use among adolescents in Argentina, Chile, and Uruguay over time.

Amid changing marijuana policies in the Southern Cone, we examined relationships between marijuana-related risk factors and marijuana use among adolescents in Argentina, Chile, and Uruguay from 2001 to 2016.

The Relationship Between Social Anxiety and Alcohol and Marijuana Use Outcomes Among Concurrent Users: A Motivational Model of Substance Use.

College students with more social anxiety symptoms are particularly vulnerable to problematic alcohol and marijuana use given their susceptibility for elevated anxiety symptoms in social settings combined with the normative nature of substance use. Existing research has established substance use as coping motivated for these students when examining alcohol and marijuana use problems separately. The next step is to determine whether students with more social anxiety who use both substances do so for similar ...

Reasons High School Students Use Marijuana: Prevalence and Correlations With Use Across Four Decades.

Changes in the legality and prevalence of marijuana raise questions about whether adolescents' reasons for using marijuana and associations between reasons for use and recent marijuana use have changed historically.

Marijuana use and driving in Washington State: Risk perceptions and behaviors before and after implementation of retail sales.

Washington is among the first states to legalize recreational use of marijuana. This study examined marijuana use and risk perceptions before and after retail sales of recreational marijuana began in July 2014, the relationship between risk perceptions and marijuana use, and the relationship between self-reported marijuana use and drug test results.

Has Self-reported Marijuana Use Changed in Patients Undergoing Total Joint Arthroplasty After the Legalization of Marijuana?

Marijuana use has become more accessible since its recent legalization in several states. However, its use in a total joint arthroplasty population to our knowledge has not been reported, and the implications of its use in this setting remain unclear.

Association of Marijuana, Mental Health, and Tobacco in Colorado.

Marijuana's evolving legality may change marijuana use patterns in adults. Co-use of marijuana and tobacco are strongly associated, and populations with mental health disorders are disproportionately likely to use either substance, but neither association has been assessed in the context of legal recreational marijuana. We assessed the associations of tobacco smoking with marijuana use and with mental health disorders in Colorado in 2015.

Modes of Marijuana Consumption Among Colorado High School Students Before and After the Initiation of Retail Marijuana Sales for Adults.

This study aimed to estimate the prevalence of different modes of marijuana consumption (e.g., smoking, ingesting) overall and by sociodemographic factors, marijuana-related perceptions, and other substance use among adolescents, as well as to characterize differences in the usual mode of consumption before and after the initiation of retail marijuana sales in 2014.

Post-traumatic stress and marijuana outcomes: The mediating role of marijuana protective behavioral strategies.

The present study investigated the mediating role of protective behavioral strategies for marijuana (PBSM) on the relationship between posttraumatic stress disorder (PTSD) and marijuana outcomes (i.e. marijuana use frequency, marijuana use quantity, cannabis use disorder (CUD) symptoms, and marijuana-related problems). Participants were 1,107 traditional age college students ( = 20.26,  = 3.32; 66.5% White, non-Hispanic; 68.8% female), who reported consuming marijuana at least once in the last 30 day...

Addendum to "The Effect of Medical Marijuana Laws on Marijuana-Related Attitude and Perception among US Adolescents and Young Adults".

Moving beyond perceived riskiness: Marijuana-related beliefs and marijuana use in adolescents.

Perceived riskiness of marijuana in adolescents has been trending downward in the context of increasing legality and availability. Low perceived riskiness has been associated with marijuana use though evidence is lacking on associations among use and more specific claims about marijuana's safety and benefit, improved understanding of which could guide clinical interventions to reduce use. We analyzed cross-sectional survey data collected from 502 adolescents aged 14-18 years recruited from an urban adole...

Marijuana protective behavioral strategies and marijuana refusal self-efficacy: Independent and interactive effects on marijuana-related outcomes.

Separately, research has identified use of marijuana protective behavioral strategies and marijuana refusal self-efficacy to be protective factors associated with less marijuana use and associated harms. To date, these factors have not been examined together. Using a large sample of college students recruited from 10 U.S. universities ( = 1,123), we examined the extent to which use of marijuana protective behavioral strategies and marijuana refusal self-efficacy have redundant, independent, or interactive e...

Trends in marijuana use among pregnant women with and without nausea and vomiting in pregnancy, 2009-2016.

Cross-sectional studies indicate an elevated prevalence of prenatal marijuana use in women with nausea and vomiting in pregnancy (NVP). However, it is unknown whether differences in marijuana use by NVP status have persisted over time as marijuana becomes more acceptable and accessible and prenatal use increases overall. We compared trends in prenatal marijuana use by NVP status in the first trimester of pregnancy using data from Kaiser Permanente Northern California's (KPNC) large healthcare system.

Marijuana use among young adult non-daily cigarette smokers over time.

Recent data regarding growth in concurrent use of nicotine and marijuana have raised concern that reductions in legal restrictions on marijuana use may increase risk for tobacco-related harms. Previous studies have shown cross-sectional links between use of both substances, but less is known about associations over time. The goal of the present study was to test the hypothesis that there is a bidirectional relationship between use of marijuana and use of tobacco products over time, such that increasing use ...

Past 30-day co-use of tobacco and marijuana products among adolescents and young adults in California.

Limited research among adolescents and young adults (AYA) has assessed tobacco and marijuana co-use in light of specific products. We examined the patterns of past 30-day co-use of tobacco and marijuana products, and the product-specific associations among past 30-day use of these substances.

Brief report: Characterization of marijuana use in us college students by state marijuana legalization status as reported to an online survey.
