A case of panic attack developing after THC-O acetate inhalation using an e-cigarette device
Aim: Tetrahydrocannabinol acetate (THC-O) is a cannabinoid-based product, and few medical studies have evaluated the effects of THC-O on humans. Recently, e-cigarettes have become popular among teenagers and young adults worldwide. However, there have been reports of people misusing this device as a delivery system for drugs of abuse.
Targeted smoking cessation for dual users of combustible and electronic cigarettes: a randomised controlled trial
Although many smokers use electronic cigarettes (e-cigarettes) to quit smoking, most continue to smoke while vaping. This dual use might delay cessation and increase toxicant exposure. We aimed to test the efficacy of a self-help intervention designed to help dual users to quit smoking. In this three-arm randomised controlled trial we recruited individuals in the USA using Facebook and multimedia advertisements. Included participants were 18 years or older, smoked at least weekly in the preceding year, and vaped at least weekly in the preceding month.
Effect of e-Cigarettes Plus Counseling vs Counseling Alone on Smoking Cessation: A Randomized Clinical Trial
Importance: Electronic cigarettes (e-cigarettes) for smoking cessation remain controversial.
Objective: To evaluate e-cigarettes with individual counseling for smoking cessation.
Design, setting, and participants: A randomized clinical trial enrolled adults motivated to quit smoking from November 2016 to September 2019 at 17 Canadian sites (801 individuals screened; 274 ineligible and 151 declined). Manufacturing delays resulted in early termination (376/486 participants, 77% of target). Outcomes through 24 weeks (March 2020) are reported.
Nicotine replacement treatment, e-cigarettes and an online behavioural intervention to reduce relapse in recent ex-smokers: a multinational four-arm RCT
This trial was curtailed due to low recruitment and while there was a suggestion in favour of single interventions reducing relapse, this did not reach statistical significance. Relapse remains an unresolved issue in smoking cessation. Extended stop smoking medication use can help, but uptake is low and several behavioural relapse prevention interventions have been found to be ineffective. However, opportunistic 'emergency' use of fast-acting nicotine replacement treatment or electronic cigarettes may be more attractive and effective, and an online behavioural Structured Planning and Prompting Protocol has shown promise. The present trial aimed to evaluate the clinical effectiveness and cost-effectiveness of these two interventions.
A Randomized Clinical Trial Examining the Effects of Instructions for Electronic Cigarette Use on Smoking-Related Behaviors and Biomarkers of Exposure Get access Arrow
Electronic cigarettes (e-cigarettes) have the potential to significantly reduce exposure to harmful constituents associated with cigarette smoking when smokers completely substitute cigarettes with e-cigarettes. This study examined patterns of e-cigarette and cigarette use, and extent of toxicant exposure, if smokers were instructed and incentivized to completely switch to e-cigarettes compared to instructions to use the product ad libitum.
Effect of Electronic Cigarettes on Smoking Reduction and Cessation in Korean Male Smokers: A Randomized Controlled Study
New approaches to electronic cigarettes (e-cigarettes) as a form of nicotine replacement therapy (NRT) may reduce the rates of tobacco-related disease and mortality. Therefore, we investigated the effect of e-cigarettes on smoking cessation compared with nicotine gum. A total of 150 subjects were randomly assigned to 2 groups and each was allocated a 12-week supply of either e-cigarettes or nicotine gum. The continuous abstinence rate, 7-day point prevalence of abstinence, smoking reduction rate and amount, and tolerability were evaluated.
A Randomized Trial of E-Cigarettes versus Nicotine-Replacement Therapy
E-cigarettes are commonly used in attempts to stop smoking, but evidence is limited regarding their effectiveness as compared with that of nicotine products approved as smoking-cessation treatments. We randomly assigned adults attending U.K. National Health Service stop-smoking services to either nicotine-replacement products of their choice, including product combinations, provided for up to 3 months, or an e-cigarette starter pack (a second-generation refillable e-cigarette with one bottle of nicotine e-liquid [18 mg per milliliter]), with a recommendation to purchase further e-liquids of the flavor and strength of their choice.
Effectiveness of a text-messaging-based smoking cessation intervention ("Happy Quit") for smoking cessation in China: A randomized controlled trial
China has the highest global prevalence of cigarette smokers, accounting for more than 40% of the total cigarette consumption in the world. Considering the shortage of smoking cessation services in China, and the acceptability, feasibility, and efficacy of mobile-phone-based text messaging interventions for quitting smoking in other countries, we conducted a mobile-phone-based smoking cessation study in China.
