What Products Contain Nicotine?

Published by at 7:57 am under Must know about smoking

nicotine Nicotine is an alkaloid found in the nightshade family of plants (Solanaceae) that constitutes approximately 0.6–3.0% of dry weight of tobacco,[1][2] with biosynthesis taking place in the roots and accumulation occurring in the leaves. In low concentrations (an average cigarette yields about 1 mg of absorbed nicotine), the substance acts as a stimulant in mammals and is the main factor responsible for the dependence-forming properties oftobacco smoking. According to the American Heart Association, nicotine addiction has historically been one of the hardest addictions to break, while the pharmacological and behavioral characteristics that determine tobacco addiction are similar to those that determine addiction to drugs such as heroin andcocaine.[5]

History

  • Step 1:

    Nicotine was first isolated as a chemical compound in 1828. According to Clemson University, nicotine was first patented for use as an insecticide additive in 1908. Nicotine has been added to some pesticides ever since. According to Laura Picket Pottorff, Colorado State University Cooperative Extension horticulturist and plant pathologist, nicotine extract is one of the oldest botanical insecticides in use today.

Tobacco

  • Step 1:

    Nicotine is present in all tobacco products. Cigarettes that are marketed as low-tar or low-nicotine still contain nicotine. Nicotine is also present in dip, snuff, packets, chewing tobacco, cigars and pipe tobacco. The nicotine in the smokeless tobaccos is absorbed during use.

Function

  • Step 1:

    Nicotine is added to many products designed as smoking-cessation aids. These products include nicotine gum, nicotine patches, nicotine lozenges and nicotine nasal sprays. They are all designed to be used instead of cigarettes, as part of a program to stop smoking. The amount of nicotine in these products varies and can be tailored to help an individual “wean off” their nicotine dependence.

Other Products

  • Step 1:

    Electronic cigarettes are “smokeless” cigarettes that deliver nicotine to the user, without the combustible by-products associated with smoking tobacco-based cigarettes. The liquid used for electronic cigarettes usually contains nicotine, although it can be purchase nicotine-free. The electronic cigarette liquid typically contains nicotine extract, propylene glycol and flavoring. The liquid can be ordered in varying nicotine strengths and flavors.

Warning

  • Step 1:

    Liquid nicotine can be especially toxic. Gloves should always be worn when using a nicotine-based pesticide. Care should be observed when handling the nicotine-based liquids used for electronic cigarettes. Any liquid nicotine, including pesticides and electronic cigarette liquids, could be fatal if handled or ingested by a child.

Trace Amounts

  • Step 1:

    Nicotine, in trace amounts, occurs naturally in eggplant, red peppers, tomatoes and potatoes.
