Without impartial and long-term studies, the true effects cannot be known.
What is known for certain is that e-cigarettes are less harmful to the smoker in a lot of ways than traditional cigarettes.
This makes them a potentially valuable tool for those who are attempting to quit smoking altogether.
But we also know that vaping still has a lot of toxins.
And that the metals that are emitted are an additional toxin that cigarettes do not have in as high a quantity.
So it’s still a much better idea to not smoke at all.
