Should tobacco companies be held responsible for smoking-related illnesses and deaths?

I feel that in some cases tobacco companies should definately be held responsible for some smoking related illnessess because, I've read that for over 50 years, the true facts about the health risks of cigarette smoking were hidden from the public.Cigarette smoking is now the  largest preventable cause of deaths in the United States. Nearly one in every five deaths in the United States is smoking related, and tobacco use results in  more 167 billion dollars.They should be held responsible especially if they hid a lot of important information from the public. This means that there can be alot of tabacco deaths that went unotice, and they probably should have been punished a long ago so why not hold them accountable now.There are a lot of dangers that come from using tabacco like: nicotine addiction, lung cancer, secondhand smoke, third hand smoke( the negative effects from tobacco are not limited to the smoke)r. Secondhand smoke is more toxic than the smoke inhaled through the filter.
