Objectives:
To evaluate predictors of dual use of cigarettes with smokeless tobacco or e-cigarettes.
Methods:
Adult smokers (N = 1324) completed online cross-sectional surveys. Logistic regression evaluated predictors of dual use and cigarette quit attempts.
Results:
Smokeless tobacco dual use was associated with past attempts to quit smoking by switching to smokeless products. E-cigarette dual use was associated with using stop-smoking medication and strong anti-tobacco industry attitudes. Ever use of stop-smoking medication was associated with quit attempts among dual e-cigarette users and cigarette-only users.
Conclusions:
Dual users are more likely than cigarette-only users to endorse certain cessation-related attitudes and behaviors. This may provide an opportunity for clinicians or others to discuss evidence-based strategies for smoking cessation.

Stimulants
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...
Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
