Nikotin: Et Instrument of Death
Så mange folks liv skæres kort af dette instrument af døden. Hvad er endnu mere tragisk? Mange af disse dødsfald kunne have været forhindret, fordi alle ved nu ved, at nikotin dræber. Alligevel ser vi ikke denne morder på posthuset væggen med en stor WANTED-etiket over sit billede.
Her er spørgsmålet: Hvorfor ikke? Hvorfor er et stof, der kan få en teenager til at blive afhængig af det inden for to uger, være så let at få? Det giver bare ikke mening. Uanset dens forklædning - cigaretter, cigarer, piptobak, tyggetobak eller snus - nikotin er simpelthen ikke sikker.
Røgskærme
Her er de kolde, grimme fakta:
- Nikotinafhængighed kan forekomme meget tidligt i livet. Jo yngre en person starter, jo større er chancen for at han eller hun bliver en tung ryger som voksen.
- Halvfjerds procent af alle high school-seniorer, der ryger i dag, vil ryge i 2007 (ikke en god graduation gave til at holde).
- Teenagere er mere tilbøjelige til at ryge, hvis deres venner eller forældre ryger.
- Lungekræft er den vigtigste årsag til kræftdød blandt kvinder og mænd; mere end 80 procent af disse kræftformer er forårsaget af rygning.
- Der er mere end 4.000 kemikalier i tobaksrøg; mindst 50 af dem har vist sig at forårsage kræft.

Nikotin: Et Instrument af Død (FORTSAT)
- Secondhand røg er en potentiel morder. Den indeholder DDT, arsen, formaldehyd og carbonmonoxid. Det er forbundet med infant lungebetændelse, pludseligt barnedødssyndrom (SIDS) og astma samt mellemøreinfektioner hos småbørn og ældre børn. Hos voksne er det forbundet med astma, slagtilfælde og hjerte-kar-sygdom, kræft og endog respirationssvigt.
- Lavt tjære, lav-nicotin cigaretter lade være med mindske risikoen for lungekræft, hjerteanfald, bronkitis eller emfysem.
- Ventilerede filtre mindsker ikke de skadelige risici ved tobakseksponering.
- Cigarrøg indeholder så mange farlige kemikalier som cigaretrøg, og det vides at forårsage kræft i mund, hals og spiserør.
- Rørrygning øger i høj grad niveauet af kulilte i blodet. Rørrøgere har en øget risiko for læber og mundkræft.
- Tuggtobak og snus er ikke sikre alternativer til cigaretter. Disse tobaksformer kan producere meget høje niveauer af nikotin i en persons blod og øge hans eller hendes risiko for nikotinafhængighed og kræft i mund, tunge og hals.
Jeg ved, at mange rygere vil stoppe, og jeg indser, at denne vanedannende vane er meget svært for mange mennesker at bryde, men vær venlig at ikke give op. Det er her citatet "Hvis du ikke lykkes første gang, så prøv, prøv igen" kommer i spil. Det er en kendsgerning, at jo flere gange du forsøger at holde op, jo bedre er dine chancer for at lykkes.
Heldigvis har vi flere muligheder i dag for at hjælpe dig med at lykkes imod denne fjende af god sundhed, men du skal tage det første skridt ved at kontakte din sundhedspersonale. Jeg ved, det er svært, men dit livs ur tikker. Der er ingen tid som nutiden for at komme i gang.

❓ Is nicotine a pain killer?
👉 Tobacco is not useful for long-term pain relief. Even though chemicals in tobacco, such as nicotine, have a pain-relieving effect, once the smoking has stopped, the pain is still present.
❓ Does nicotine make you feel more pain?
👉 “Nicotine-induced pain relief is short-term. Over time, smoking may actually worsen your pain,” says pain management specialist Crawford Barnett, MD. Smokers are nearly three times as likely to get lower back pain. Smoking may aggravate abdominal pain and joint pain, as well.
❓ Does nicotine protect brain?
👉 Nicotine is known to protect neurons from stress-induced apoptosis [35]. Given our preliminary data (Fig. 2), we hypothesized that the neuroprotective effect of nicotine might depend on SIRT6.
❓ What happens if you drink liquid nicotine?
👉 If they put it in their mouth even without swallowing it will be absorbed into the mucous membranes, just like nicotine gum. If they swallow, it will be absorbed in the intestinal tract. If they spill it on their ​skin, it's absorbed through the skin just like a nicotine patch," said Dr. Quinlan.
❓ What happens if you inject nicotine into your bloodstream?
👉 The moment nicotine enters the body, it is metabolized into cotinine, which reaches a concentration that is 2–4 times higher than that of nicotine within an hour. In the present case, the higher levels of nicotine than cotinine in all samples suggested an acute death due to the high concentration injected nicotine.
❓ Does nicotine help you sleep?
👉 While you're smoking: Nicotine disrupts sleep – and smoking can also raise the risk of developing sleep conditions, such as sleep apnea. But since nicotine is a stimulant, smoking can mask your exhaustion. After all, if you're feeling sleepy, a hit of nicotine can wake you up and make you feel alert the next day.
❓ Does nicotine help poop?
👉 Laxative effect This type of laxative is known as a stimulant laxative because it “stimulates” a contraction that pushes stool out. Many people feel nicotine and other common stimulants like caffeine have a similar effect on the bowels, causing an acceleration of bowel movements.
❓ What does nicotine do to your brain?
👉 As a neurotransmitter, nicotine increases the brain's levels of dopamine, stimulating its reward centers and making the person ingesting it feel good. It takes just 10 seconds for nicotine to reach the brain after it is inhaled or ingested. Most people build up a resistance to nicotine.
❓ How long does nicotine stay in your system?
👉 People also process nicotine differently depending on their genetics. Generally, nicotine will leaves your blood within 1 to 3 days after you stop using tobacco, and cotinine will be gone after 1 to 10 days. Neither nicotine nor cotinine will be detectable in your urine after 3 to 4 days of stopping tobacco products.
❓ Is nicotine good for memory?
👉 Preclinical models and human studies have demonstrated that nicotine has cognitive-enhancing effects, including improvement of fine motor functions, attention, working memory, and episodic memory.
❓ What is nicotine poisoning?
👉 Nicotine poisoning. Nicotine poisoning describes the symptoms of the toxic effects of nicotine following ingestion, inhalation, or skin contact. Nicotine poisoning can potentially be deadly, though serious or fatal overdoses are rare. Historically, most cases of nicotine poisoning have been the result of use of nicotine as an insecticide.
❓ What is the LD50 of nicotine in rats?
👉 The LD50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 0.5–1.0 mg/kg can be a lethal dosage for adult humans, and 0.1 mg/kg for children.
❓ What is nicotine used for?
👉 Nicotine is a chiral alkaloid that is naturally produced in the nightshade family of plants (most predominantly in tobacco and Duboisia hopwoodii) and is widely used recreationally as a stimulant and anxiolytic. As a pharmaceutical drug, it is used for smoking cessation to relieve withdrawal symptoms.
❓ Is nicotine poisoning a reliable weapon?
👉 The fact is, nicotine poisoning is not a reliable weapon. Lethal amounts of nicotine need to be ingested, absorbed or injected. And it's not easy to disguise nicotine in food. If a person did ingest a large amount of nicotine, he would most likely vomit much of it out.
