I smoked probably at least as much pot as anyone here, and it has had no noticeable negative impact on my health. Once I quit smoking cigarettes, all the respiratory crap, the hacking cough, the sinus infections, all went away. My lungs are perfectly clear.
Well good for you. I know many, many others who have not fared as well, although many of them still insist that their habit is good for them. My wife who is a retired nurse and department head can spot a long-term pot smoker from a mile away. Living in Washington this describes a high percentage of our long term friends and associates. I am not going to try and name all the signs she is aware of, but as I said previously cognitive issues are number one and denying that marijuana has any negative effects on them is number two. LOL!
