I don’t smoke and I don’t vape, and if that also describes you, I would argue that it would be good advice to keep it that way.
If you smoke, I would urge you to stop doing so. If you find it difficult to do so, I would argue that it would still be good advice for you considering shifting to e-cigarettes.
If you currently vape, then you have a decision to make about whether to continue to do so. On this, I wouldn’t be comfortable giving advice. Hopefully, though, that decision will be guided by facts and evidence.
