Symptoms of Wrinkles Wrinkles are a symptom of aging, but some early signs of wrinkles can include fine lines. Later, deep wrinkles may form, particularly around the mouth, nose, eyes, and forehead.
Smoker melanosis in a patient consuming 2 packs of cigarette per day. Smoking or the use of nicotine-containing drugs is the cause to Smoker's melanosis. [10] [11] Tar-components (benzopyrenes) are also known to stimulate melanocytes to melanin production, and other unknown toxic agents in tobacco may also be the cause.

The LD 50 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. [19] [20] However the widely used human LD 50 estimate of 0.5–1.0 mg/kg was questioned in a 2013 review, in light of several documented cases of humans surviving much higher doses; the 2013 review suggests that the lower limit causing fatal ...
