1
00:00:00,040 --> 00:00:02,080
Speaker 1: Now our groundbreaking new study has for the first time

2
00:00:02,160 --> 00:00:05,200
Speaker 1: linked vaping with irreversible lung disease. So this is a

3
00:00:05,200 --> 00:00:08,200
Speaker 1: study by John Hopkins Johns Hopkins University. It looked at

4
00:00:08,200 --> 00:00:11,200
Speaker 1: health data from about a quarter of a million people

5
00:00:11,200 --> 00:00:14,720
Speaker 1: found a significant link between vaping and COPD, which is

6
00:00:14,760 --> 00:00:16,599
Speaker 1: the fourth leading cause of death in New Zealand. Doctor

7
00:00:16,600 --> 00:00:19,520
Speaker 1: Stuart Jones is a respiratory physician and is with us

8
00:00:19,560 --> 00:00:20,599
Speaker 1: now has Stewart.

9
00:00:21,960 --> 00:00:23,119
Speaker 2: Cut to Heather, how are you?

10
00:00:23,239 --> 00:00:25,640
Speaker 1: I'm very well, thank you. It seems to me, are

11
00:00:25,640 --> 00:00:28,640
Speaker 1: we surprised that if you're inhaling this weird stuff into

12
00:00:28,640 --> 00:00:31,520
Speaker 1: your lungs that you're probably going to get COPD?

13
00:00:32,479 --> 00:00:38,200
Speaker 2: The answer is no, no, If the respiratory community aren't

14
00:00:38,240 --> 00:00:43,519
Speaker 2: surprised at all that this result has come out, I

15
00:00:43,560 --> 00:00:47,159
Speaker 2: guess it's what we've been warning about all along with

16
00:00:48,120 --> 00:00:52,440
Speaker 2: the vaping that's been going on, is that it does

17
00:00:52,640 --> 00:00:54,760
Speaker 2: I mean we've none for a while it's causes damage,

18
00:00:54,840 --> 00:00:57,480
Speaker 2: It causes inflammation to the airways and things like that,

19
00:00:57,520 --> 00:01:00,400
Speaker 2: but now we have a little bit more concrete evidence

20
00:01:00,440 --> 00:01:04,319
Speaker 2: that it's doing more permanent damage to those airways.

21
00:01:05,120 --> 00:01:08,120
Speaker 1: Now, can we say, based on this whether we think

22
00:01:08,480 --> 00:01:10,680
Speaker 1: vaping is necessarily better than ciggies.

23
00:01:12,440 --> 00:01:16,120
Speaker 2: Yeah, Hither, it is important to note that that in

24
00:01:16,160 --> 00:01:21,600
Speaker 2: the study, it also the study demonstrated a higher incidence

25
00:01:21,800 --> 00:01:26,720
Speaker 2: of incidents COPD and people who were smoking combustible cigarettes.

26
00:01:27,280 --> 00:01:31,520
Speaker 2: So the rates of CPD that occurred with vaping alone

27
00:01:31,920 --> 00:01:37,240
Speaker 2: weren't as high as combustible cigarettes, but still significant. And

28
00:01:38,520 --> 00:01:42,720
Speaker 2: the other key point for this study is that the

29
00:01:42,880 --> 00:01:47,640
Speaker 2: worst people off were the people who combined cigarettes and vaping.

30
00:01:47,720 --> 00:01:51,120
Speaker 2: And that's what I'm worried that many people are still doing.

31
00:01:52,120 --> 00:01:54,200
Speaker 1: So wait are you saying, because there were a lot

32
00:01:54,200 --> 00:01:56,040
Speaker 1: of people who will be smoking the ciggies maybe when

33
00:01:56,040 --> 00:01:57,440
Speaker 1: they're on the beers, and then the rest of the

34
00:01:57,440 --> 00:01:59,000
Speaker 1: time they'll just be doing the vaping to try to

35
00:01:59,000 --> 00:02:01,280
Speaker 1: cut down the bad sty But would they actually be

36
00:02:01,280 --> 00:02:02,920
Speaker 1: better off just packing one of the two and going

37
00:02:02,920 --> 00:02:04,320
Speaker 1: for it rather than doing the combo?

38
00:02:05,200 --> 00:02:08,840
Speaker 2: Yeah? Correct, correct, Because I mean we know that it

39
00:02:09,200 --> 00:02:12,680
Speaker 2: damages the airways in different ways, so the mechanism of

40
00:02:12,760 --> 00:02:17,920
Speaker 2: damage to the airways is different between vaping and cigarette smoking.

41
00:02:18,639 --> 00:02:21,920
Speaker 2: And effectively, what you're doing with the dual use is

42
00:02:21,960 --> 00:02:28,760
Speaker 2: you're doubling up. So that's definitely a no go. So

43
00:02:29,480 --> 00:02:34,120
Speaker 2: you know. Yeah, so vaping definitely does cause damage to

44
00:02:34,120 --> 00:02:37,280
Speaker 2: the airways. The only people who might get a benefit

45
00:02:37,560 --> 00:02:42,040
Speaker 2: is those people who can't stop smoking the cigarettes, but

46
00:02:42,160 --> 00:02:44,200
Speaker 2: they would only get the benefit if they make a

47
00:02:44,240 --> 00:02:45,080
Speaker 2: complete switch.

48
00:02:45,240 --> 00:02:47,120
Speaker 1: Okay, hey Stuart, thank you. I mean there is some

49
00:02:47,200 --> 00:02:49,280
Speaker 1: at least some useful information there for people if you

50
00:02:49,560 --> 00:02:52,240
Speaker 1: choose which way you're going to die, but don't go

51
00:02:52,320 --> 00:02:54,800
Speaker 1: for both ways, because that's not a good idea. For

52
