Here's my two cents. Smoked from age 13 to 23. Quit for 6 1/2 years. Went back in 1981. Still smoking. I am 61. During that time I quit once for 5 months and once for 9 months. Didn't help me. My father smoked too from a young age; something like 2 packs a day plus cigars. Quit when I was very young (don't remember him smoking). Diagnosed with PD in his 70's but symptoms started way before then. He lost his sense of smell in his early 60's. Dr. said it was from a cold and he may or may not get it back. They didn't know then what they know now. In 2000 he fell and broke his hip. Lasted about 2 months and passed away. My Goddaughter who previously worked with a doctor at Thomas Jefferson Hospital in Philadelphia worked with primates doing research on PD. She said it is neuroprotective but they had to give the primates so much nicotine they vomited. I'll pass, thank you.
