It's a black owl cigarette from Vietnam.

cigarettes are a kind of tobacco products. The method is to dry tobacco and shred it, and then grow it into a barrel-shaped strip with a diameter of 12mm and a paper roll. When smoking, one end is lit, and then the smoke generated by breathing through the mouth at the other end. Cigars are smoked by rolling tobacco into cylindrical strips.

The main difference between cigarettes and cigars is that cigarettes are small in size, and tobacco is refined and chopped. Cigarettes were first popular in Turkey, and local people like to roll up tobacco in newspapers and smoke it. During the Crimean War, British soldiers learned the method of smoking from the soldiers of the Ottoman Empire at that time, and then spread to different places.

On June 25th, 1843, France began to manufacture the first batch of cigarettes for commercial sale. Later, cigarettes became popular everywhere.

Health effects

Effects of tobacco on the brain: Nicotine spreads to the whole body through lung mucosa and oral mucosa. After entering the brain, nicotine can mimic acetylcholine, a central nerve transmitter, and bind to nicotine receptors on the surface of many neurons. Nicotine can stimulate the central nervous system, especially in the "reward circuit".

It can release more dopamine by activating related nerves. Harmine and norepinephrine contained in tobacco can keep dopamine, serotonin and norepinephrine in synapses at a high level by inhibiting the activity of catabolic enzymes. With the strengthening of the role of dopamine, serotonin and norepinephrine, people will be more awake and more focused, thus alleviating their worries and enduring hunger. Tobacco can cause nausea, dizziness and headache.

Tolerance and dependence: Frequent smoking can keep nicotine content in the brain at a high level all the time. Neuron receptors are less and less sensitive to nicotine, and the stimulating effect on dopamine release is also weakened. The original cigarette consumption can no longer satisfy the smoker's pleasure, and smokers are tolerant to nicotine.

When a smoker stops smoking for several hours (sleep time), the nicotine content in the body drops, and the neuron receptors become extremely sensitive. At this time, the activity of acetylcholine exceeds the normal level, which makes the smoker become irritable and want to smoke very much. At this time, if you can smoke a cigarette, you can over-stimulate the neuron receptor and promote the release of dopamine in large quantities. Through this phenomenon, we can understand why the first cigarette every day can bring great pleasure to the "old smoker", and smokers are therefore caught in a vicious circle of increasing addiction.
