Can an individual sue tobacco companies for wrongful death related to smoking?

My wife died June 2nd 2014 at age 65. We both started smoking in our teens when cartoon characters were used by tobacco companies to encourage kids to start smoking. I have medical proof that her health issues leading up to her death was caused by years of smoking. We both tried many times to quit, but failed until about 5 years prior to her death. I was then forced to refuse to buy any more cigarettes.
