Smoking Leads to Cancer?!

Sometimes med students, physicians, and everyone else involved in the health care industry forget that our knowledge about health and medicine isn't all common knowledge that we can expect everyone to know. Apparently, not everyone knows that St. John's Wort is actually a medication and it has many drug interactions you need to be aware about before you fill a prescription if you are taking St. John's Wort. However, there are some things that I think the general public should be expected to know. One of those things is that smoking leads to cancer! Seriously, people NEED to know this! Lung cancer is a terrible way to die and you need to be aware that smoking greatly increases your likelihood of lung cancer. If people knowingly risk lung cancer and continue to smoke, that's one thing...but people who start, or advocate, smoking without knowing how fatal smoking can be...that really shouldn't happen in this day and age!
