The rise in vaping is of great concern because the parts encompassing in greater cognitive activities including the prefrontal cortex of the brain continues to develop into the 20s. [1] Nicotine exposure during brain development may hamper growth of neurons and brain circuits, effecting brain architecture, chemistry, and neurobehavioral ...
Nicotine promotes the growth of blood vessels, which can supply tumors and speed tumor growth. [82] As of 2015, long-term vaping had not been assessed for malignancy in individuals with a susceptibility for tumor growth. [152] The effects of nicotine on the sympathoadrenal system could stimulate growth in cancers already present. [262]
[15] [16] One issue is the need to separate the effects of vaping from the effects of smoking among users who both vape and smoke. [note 4] [17] E-cigarettes containing nicotine are more effective than nicotine replacement therapy (NRT) for smoking cessation. [18] [19] Vaping is likely far less harmful than smoking, but still harmful.

Vaping has an immediate effect on how well the user’s blood vessels work, even if the e-cigarette doesn’t contain nicotine, according to new research.
Nicotine effect on weight appears to result from nicotine's stimulation of α3β4 nAChR receptors located in the POMC neurons in the arcuate nucleus and subsequently the melanocortin system, especially the melanocortin-4 receptors on second-order neurons in the paraventricular nucleus of the hypothalamus, thus modulating feeding inhibition.
The effects of growth hormone (GH) deficiency vary depending on the age at which they occur. Alterations in somatomedin can result in growth hormone deficiency with two known mechanisms; failure of tissues to respond to somatomedin, or failure of the liver to produce somatomedin. [48]
The firsthand aerosol is harmful for many reasons: Most e-cigarettes (99%) contain nicotine (though many do not disclose it), which can harm the developing adolescent brain (that keeps developing ...
