Ive heard that many stupid comments from people who have never even tried it.The people i know that have smoked for years like 25 yrs say its all good and theres nothing wrong with them.My mum knows i smoke and she hates it but i just be truthful and ive heard some of the most ridiculous stories that just make me laugh and then i tell her that it makes me want to smoke more.Just for some fun to get her going.
