Snus is a smokeless, moist tobacco product that originated in Sweden, consumed by placing a small pouch under the upper lip. The question of whether snus produces a “high” is common, stemming from the intense physical sensations new users often report. This article examines how snus delivers nicotine and the specific physiological effects this substance has on the body, clarifying the difference between a stimulating “buzz” and a true psychoactive high.
What is Snus and How Nicotine is Absorbed
Snus is a finely ground, often pasteurized, tobacco product typically sold in small, tea bag-like pouches. The user places one of these pouches between the upper lip and the gum, where it remains for an extended period, sometimes up to two hours. Unlike traditional chewing tobacco, snus does not require the user to chew the product or spit out the resulting liquid.
The nicotine is absorbed directly through the oral mucosa, the moist lining of the mouth, and then enters the bloodstream. This absorption pathway bypasses the lungs entirely, resulting in a slower onset of nicotine delivery compared to smoking a cigarette. However, this method often allows for a higher, more sustained concentration of nicotine in the blood over time than other smokeless products, providing a prolonged effect. The alkalinity of the snus product, adjusted by ingredients like sodium carbonate, also increases the absorption efficiency of the nicotine.
The Physiological Response to Nicotine
Nicotine is classified as a stimulant, which is distinct from psychoactive euphoric drugs like cannabis or cocaine that cause a true “high.” The sensation experienced by snus users is more accurately described as a “buzz” or a “rush,” which is a rapid, temporary alteration in physical and mental state. This effect is generated when nicotine molecules bind to specific receptors in the brain.
This binding action triggers the release of several neurotransmitters, most notably dopamine and adrenaline. The surge of dopamine activates the brain’s reward pathways, leading to temporary feelings of pleasure and mild euphoria. Simultaneously, the release of adrenaline causes a physical rush, characterized by increased heart rate, elevated blood pressure, and heightened alertness.
The nicotine delivery from snus contrasts with the rapid, intense peak and quick drop associated with smoking. Snus provides a slower, more prolonged release of nicotine that maintains a steady level in the bloodstream. This sustained delivery leads to a longer-lasting feeling of relaxation and focus, rather than the sharp, short-lived “kick” that accompanies inhaling nicotine. The resulting experience, while pleasurable and stimulating, does not involve the significant cognitive impairment or hallucinatory effects that define a true drug-induced high.
Acute Side Effects and Toxicity
The intense sensations experienced by new snus users, or those consuming a high-dose product, are often misidentified as an altered state. These effects are symptoms of acute nicotine toxicity, which occurs when the body receives more nicotine than it can comfortably process. The body’s adverse reaction to the overdose manifests as unpleasant physical symptoms.
Common signs of this acute toxicity include lightheadedness, dizziness, and nausea, which can progress to vomiting in severe cases. Users may also experience a rapid heartbeat (palpitations) and excessive sweating. These physical reactions signal an overwhelmed system, and the resulting feeling of being “out of it” is a direct consequence of physical distress, not a euphoric state. The intensity of these side effects is directly related to the dose of nicotine and the individual’s tolerance level, with higher nicotine content products often inducing stronger reactions.
