One Minute of Marijuana Secondhand Smoke Exposure Substantially Impairs Vascular Endothelial Function Vascular Medicine
Conclusions One minute of exposure to marijuana SHS substantially impairs endothelial function in rats for at least 90 minutes, considerably longer than comparable impairment by tobacco SHS. Impairment of FMD does not require cannabinoids, nicotine, or rolling paper smoke. Our findings in rats suggest that SHS can exert similar adverse cardiovascular effects regardless of whether it is from tobacco or marijuana.

Online Patient –Provider E-cigarette Consultations
Conclusions Examination of online patient–provider communications provides insight into consumer health experience with emerging alternative tobacco products. Patient concerns largely related to harms and safety, and patients preferred provider responses positively inclined toward e-cigarettes. Lacking conclusive evidence of e-cigarette safety or efficacy, healthcare providers encouraged smoking cessation and recommended first-line cessation treatment approaches.

Reasons for current E-cigarette use among U.S. adults
Publication date: Available online 7 September 2016 Source:Preventive Medicine Author(s): Deesha Patel, Kevin C. Davis, Shanna Cox, Brian Bradfield, Brian A. King, Paul Shafer, Ralph Caraballo, Rebecca Bunnell E-cigarette use has increased rapidly among U.S. adults. However, reasons for use among adults are unclear. We assessed reasons for e-cigarette use among a national sample of U.S. adults. Data were collected via online surveys among U.S. adults aged 18 or older from April through June 2014. Descriptive and multivariate regression analyses were conducted to assess reasons for e-cigarette use among 2448 current e-ciga...

The challenge of reducing smoking in people with serious mental illness
Publication date: October 2016 Source:The Lancet Respiratory Medicine, Volume 4, Issue 10 Author(s): Ratika Sharma, Coral E Gartner, Wayne D Hall The high prevalence of smoking in people with serious mental illness contributes substantially to the disproportionately high morbidity and premature mortality in this population. There is an urgent need to help people with serious mental illness to quit smoking. We discuss competing explanations for the high prevalence of smoking in people with serious mental illness and the effectiveness of available smoking cessation interventions. We propose trials of harm reduction options,...

Programmable carbon nanotube membrane-based transdermal nicotine delivery with microdialysis validation assay
Publication date: January 2017 Source:Nanomedicine: Nanotechnology, Biology and Medicine, Volume 13, Issue 1 Author(s): Gaurav Kumar Gulati, Tao Chen, Bruce Jackson Hinds To evaluate the performance of switchable carbon nanotubes (CNT) membrane devices for transdermal nicotine delivery, we have developed an in-vitro microdialysis method that allow us to detect variable transdermal fluxes of nicotine through CNT devices and can be applied directly to in-vivo studies. Microdialysis membranes were placed beneath the porcine skin and its nicotine levels increased 6-8 times when the CNT membrane on skin was turned from OFF to ...

Overview of Electronic Nicotine Delivery Systems: A Systematic Review
Conclusions Studies indicate that ENDS are increasing in use, particularly among current smokers, pose substantially less harm to smokers than cigarettes, are being used to reduce/quit smoking, and are widely available. More longitudinal studies and controlled trials are needed to evaluate the impact of ENDS on population-level tobacco use and determine the health effects of longer-term vaping.

Unintentional Pediatric Ingestion of Electronic  Cigarette Nicotine Refill Liquid Necessitating Intubation
We present a case report of a 6-year-old female who developed severe toxicity and required intubation after an unintentional oral ingestion of approximately 703 mg (35 mg/kg) of liquid nicotine, with accompanying serum and urine concentrations of nicotine and its metabolites. Analysis of the ingested liquid suggests a nicotine concentration of 140.6 mg/mL in the purchased commercial product, or 234% of its labeled concentration. Clinicians should be aware of these products and the potential severity of toxicity they may incur.

Long-term Quit Rates in Fax-Referred as Compared to Self-Referred Tobacco Quitline Registrants
Conclusions Although differences in sociodemographics, tobacco use behavior, and Helpline services were observed between fax-referred registrants and self-callers, quit outcomes at follow-up did not differ. This observational study has important implications for tobacco control initiatives as it shows patients fax-referred by hospitals and clinics to quitlines may be as successful as self-callers in quitting smoking.

U.S. adults' addiction and harm beliefs about nicotine and low nicotine cigarettes
Publication date: Available online 27 December 2016 Source:Preventive Medicine Author(s): Erin Keely O'Brien, Anh B. Nguyen, Alexander Persoskie, Allison C. Hoffman This research described U.S. adults' beliefs about nicotine and low nicotine cigarettes (LNCs) using the nationally-representative Health Information National Trends Survey (HINTS-FDA 2015; N =3738). About three quarters of people either were unsure of the relationship between nicotine and cancer or incorrectly believed that nicotine causes cancer. People who were non-White, less educated, age 65+, and never established smokers were most likely to be unaware t...
