I believe without a shadow of a doubt that pharmaceutical companys are worse than Enron in their prime. when are we as americans going to stand up and say enough of the bullshit, give it to us straight foward. you don't have to protect us anymore. trust me, after seeing the pics of britany spears crotch, I need no protection from anything anymore. lol! skunk, the reason that I brought up the remarks about improving vision is I believe smoking to be the opposite on vision ability. I was bless, if you can call it that, with 20-10 vision. my family doctor has a hard time believing I have it and checks my vision everytime I go to see him. now when I smoke, my vision changes to bad. I have to squint to see things and I do not drive at night due to fear of possibly crashing into somebody. but this is only when I smoke, other than that, my vision is perfect.
