Credible vs Non- Credible Sources

A source that has been a non credible source has been Wikipedia. Wikipedia is a non credible source because that kind of website lets anyone post their input to any topic even if they don't know anything about that particular topic. That means that a twelve year old kid could comment about heart surgery and how to perform it if he chose to. On another note there are lots of professors and specialist who post there knowledge on Wikipedia. On a site like this one you have to know the real specialist from the fakes. This is the type of source that allows anyone to express their feelings and knowledge of a certain issue or blog. I don't think that this is a credible source because for example, I read a blog on Wikipedia about breast implants and at first the comments were very factual and towards the end the comments went from factual to ridiculous. Towards the end they started talking about breast implants and when they were going to get them. Also how they would dress their implants up. This is the result of a non credible source.

A credible source that I found is http://www.pwc.k12.nf.ca/PROJECTS/b2201/moore/smoking/index.html. This source is a very good source to use because it only has professional articles and sources to back up the articles. So the reader could research on the background of the authors of the articles. On this website I found out that Ammonia is a toxic colorless gas with a very sharp odor. I also learned that Nicotine comes in two forms:acid(bound) and base (free). In tobacco smoke, free nicotine molecules vaporize more easily than bound nicotine molecules. Once nicotine vaporizes into a gas, it is quickly absorbed by the lungs and distributed throughout the human body. The tobacco companies know that ammonia is a key factor to enhancing the effect of their drug. So they discovered that adding ammonia to the cigarette manufacturing process helps convert bound nicotine molecules in tobacco smoke into free nicotine molecules. This process is known as "freebasing." Similar to the chemical process of freebasing cocaine, the end result is an enhanced effect of the drug on the user. This is an enhancement risk of cancer and lung failure. It is an enhanced chance at death. This is a credible source to me because it is accurate.
