Why would you smoking cause my uncle to pass away? Your argument isn't what I'm saying. There are lots of people that have one or two cigarettes a month and suffer no ill effects from it. Not every person starts smoking packs a day because they smoked one. Some people can handle addictive substances, some people can't.
My uncle passed away.
There are also people that have 1 or 2 cigarettes that get lung cancer.
Just because someone suffers no ill effects does not make it safe.
