Tobacco Control
|February 27, 2014
Summary
Snus use for harm reduction in the USA is low. Most users try it out of curiosity but quit due to preference for other tobacco products or dislike of snus.
Area of Science:
- Tobacco harm reduction
- Public health interventions
- Consumer behavior
Background:
- Sweden has seen reduced smoking harm with snus use.
- The USA is exploring snus as a potential harm reduction strategy.
Purpose of the Study:
- To assess snus receptivity among US adults.
- To determine if snus can reduce cigarette smoking harm in the USA.
Main Methods:
- Dual frame telephone and mail surveys conducted in 2011-2012.
- Over 5000 adults surveyed in Indianapolis and Dallas/Fort Worth.
- Measured trial, ever use, current use, and reasons for use/quitting.
Main Results:
- Among male smokers, 29.9% ever tried snus; 4.2% were current users.
- Current snus use was minimal among female, former, and never smokers.
- Reasons for trial included curiosity and low cost; reasons for quitting included preference for other tobacco and dislike of snus.
Conclusions:
- Low snus adoption rates suggest limited impact on US smoking patterns.
- Current marketing strategies do not appear to drive widespread snus use for harm reduction.

01:30Nucleophilic Aromatic Substitution: Addition–Elimination (SNAr)
3.0K
Nucleophilic substitution in aromatic compounds is feasible in substrates bearing strong electron-withdrawing substituents positioned ortho or para to the leaving group. The reaction proceeds via two steps: the addition of the nucleophile and the elimination of the leaving group.
The reaction begins with an attack of the nucleophile on the carbon that holds the leaving group. This results in the delocalization of the π electrons over the ring carbons. The resonance interaction between...

01:23Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
1.8K
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...

01:29Stimulants
1.4K
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
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...

02:15SN1 Reaction: Stereochemistry
8.7K
This lesson provides an in-depth discussion of the stereochemical outcomes in an SN1 reaction.
In the first step of an SN1 reaction, the bond between the electrophilic carbon and the leaving group ionizes to generate the carbocation intermediate. The second step of the mechanism is the nucleophilic attack.
In the formed carbocation, the positively charged carbon is sp2 hybridized with a trigonal planar geometry. As all the three substituents lie on the same plane, a plane of symmetry for the...

01:24Substance Use Disorders Affecting Sleep
610
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:23Drugs Acting on Autonomic Ganglia: Stimulants
2.2K
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...
