Cigarettes or Weed ? Which is worse for your lungs? Well this question has been asked over and over again. Just do a quick Google search on it and you will see what I mean. And there seems to be just as many opinions. However it is very hard to find an unbiased opinion on the matter. Many people who do not use Marijuana, feel that since Tobacco is legal and Marijuana is not, then obviously Marijuana is worse for you,because if it werent then it would be legal. (Yes, I have read statements such as this before.) Then on the other hand you have the users stating that cigarette smoke is however many times worse for you because of all the chemicals in it, namely Tar and Nicotine. With no one really having any sources for their info. People also tend to get off topic and start rambling about all kinds of stuff, I am only interested about the effects on the lungs. I saw one post that caught my eye, It read "This is the stupidest topic ever. Why not just ask which is worse for you, eating rat poison or drinking bleach?" Well this is a perfect example of "blind opinion". This person obviously does not use either one, so their "opinion" means absolute squat to me. What I am trying to ascertain from this is, which one is worse for the lungs? We already know that neither of them are "good". We also know that neither cigarettes nor Marijuana will kill you as quickly as drinking bleach or eating rat poison, so lets keep the comments as "intelligent" and on topic as possible. So, of course anyone can chime in with their "opinion", but if you have some good resources to back your arguments then that would be great. I myself am going to go looking for info on the matter and see what I can dig up. Maybe together we can solve this mystery, or at the very least come up with multiple "opinions" and be no further than we are right now. Hope to here from Y'all .
