l know someone who has been smoking since they were 12 and now they are almost 20. They have been smoking crazy amounts of weed that even l cant imagine how that can be possible. Anyways, lets say everyday about almost half an ounce a day everyday, yes every single day. l know that is bad and it is up to that person to stop on their own, l have tried and it has failed.They said as long as it is not ciggarettes, its much safer. But im not sure if that is true. I am worried about their health, and l dont want them to suffer at a later age, that would absolutely break my heart. l know that ciggarette smoking causes horrible long term damage, as with any smoking l suppose, but will marijuana smoke cause cancer or COPD? l need to know the facts and l need to know people who have smoked a large amount of weed and have grown old and have no disease or people who have and do have diseases?

l have been smoking weed since l was 13 im 19 now and recently l tested positive for the tuberculosis skin test so they had to check my lungs thoroughly and the doctor said my lungs were fine l dont smoke half an ounce a day though cuz l smoke kush maybe he should try a more potent kind of marijuana so he doesnt need to smoke so much

my dad had COPD which was aggravated my smoking. He was a regular in hospital unil he passed away 2 weeks ago (he hd empheysemia which is also known as COPD) . there was a regular man on the ward who had never smoked a thing in his life & he had empheysemia badly. Like my dad was, he is on permenant oxygen. Now the man is son smoked just weed. He had empheysemia or COPD, which ever u want to call it, as its the same thing. The effects of smoking (doesnt matter what) is the same, the long term lasting damage is permemnant. Not to mention the effect long lasting damage smoking weed does....your friend would be wise to quit smoking everything, the lungs still bcomedamaged just the same as smoking B & H.
