My grandparents on my mother's side smoked very heavily, and also had drinking problems.
I can't even stand to be around an environment where there is any smoking. I have an allergic reaction(watery eyes, sneezing, coughing, sore throat), plus the smell is so foul it simulates symptoms equivalent to that of the stomach flu.
As far as drinking. Never once, in my entire life, have I consumed an alcoholic beverage. Normal occasional dosages of cough suppressants are the closest I've come, I guess.
Aren't I a GOOD little boy!
