I general I would say there is scant research on the subject. I'm talking about peer-reviewed research publications here. Not some pdf somebody self-publishes. Research is good because it allows us to make informed decisions. Don't you want to use the healthiest product possible? Also, I think government regulation of consumables is a good thing. It is easier to do that effectively if there is good research on the subject.
First off welcome aboard
I know it helped me quit smoking. Went from a pack/pack and a half a day for 27 years to only having about 5 or 6 packs in the last 2 months. And you can't say that the scores of people who have quit, and/or who have gone from pack+ a day smokers to under a pack a week is a statistical fluke.
Yes we want the healthiest product available, for the most part. With that said why is most of the meat in a super market injected with anti-biotics, 15% saline/broth & processed out nuetriants which are put back in with artificial chemicals? That doesn't sound healthy, and it isn't but it's a billion dollar industry.
Scientific peer review is the cornerstone of science (even back to the days of the Greek). The problem now in days is that depending on who is funding the research? Diamond Walnuts backed up a health claim by siting 5 independent, peer reviewed papers saying that walnuts helped lower cholesterol. A group of cherry growers did the same thing with research on cherries easing the pain of arthritis. A bunch of FDA beuracrats with no scientific background told them to cease and desist becuase it turned their natural products into drug which would then need to go through FDA testing.... I'm on the liberal side of moderate, so it's not like I am some gun toting militia nut from Montana (no offense to people from Montana) who lives in a shack writing manifestos.
The FDA and USDA can't even keep outbreaks of food happening.
We do need some regulation, so do a lot of other things. The bias towards personal vapers for example. How come these standers are not applied to tobacco products?
Do we want to know the products we are using are safe? You know we do. But have you looked at the list of side effects on prescriptions? I wonder if this nicotine juice makes me have thoughts of suicide? Oh no this new personal vaper battery caused pritism causing serious nerve and cardio vascular damage in my man bits.....
Doctors are being told/sold by pharmcutical companies to write prescriptions for new anti-depressants instead of prescribing stand bys like lithium, benadizapan, and others becuase the pharma companies no longer have a patent on those drugs and make less money off of them.
Sorry to sound a bit whiny but we're cynical of a lot of the claims made again PVs. Is vaping as safe as not vaping? Probably not. Is it safer than smoking? I'd be your slave for 5 years if vaping is more of a threat to my own health and those around me (that used to be breathing in second hand smoke).
