What is worse for you, Camel cigarettes or Marlboro?

Does it really matter?  I think this question is similar to asking "what's worse for you getting hit by a Honda Civic, or a Honda Accord".

I believe Marlboro has slightly higher levels of the various poisons that are in cigarettes; however, if you smoke Camels you may be inclined to smoke more of them due to the lower levels of nicotine and poison.
