Re: Smokers lungs
They showed us a similar video at school back in the mid to late 70s. Of course in those days that meant the OHP and a white screen in the assembly hall.
It did not stop me smoking. But I knew full well what smoking does and I was always trying to quit (which happened every year and finally in my mid 30s). I think I caught it just in time but as an ex smoker you are always at risk of COPD in old age. These days a bigger risk is acid reflux and possibly pollution.
It's definitely a good idea to show kids these images. But IMO young people are far more clued up about smoking in that it's no longer cool and acceptable. When I was growing up it was still cool and a way to socialise and make new friends. I suppose they vape now or smoke dope.
