Harvard conducted an animal study in 2015 to determine addictiveness of nicotine.


To their surprise they couldn’t get any animals to be addicted to strict nicotine in water.
So researchers requested documents of tobacco companies and in the documents they learned that tobacco product manufacturers figured out in the 70’s that no body would repurchase ‘light cigarettes’, so they had to figure out how to make the tobacco products addictive.
Harvard learned in 2015 what the tobacco giants did to make tobacco products and NICOTINE addictive.
They added a chemical called Pyrazines that is highly addictive and they have been doing it ever since.
Nicotine is not the addictive substance in tobacco products, pyrazine chemicals make nicotine addictive.
Pyrazines are just one of 600 approved chemicals that the FDA allows tobacco manufacturers to add to their products in the USA.
Wonder what all the other ones are. Here is a link to the Harvard study and articles discussing their findings that NICOTINE is not addictive.
