Hoser: I would say that the jw ban on using tobacco has been a benefit to health
There is another side to this. It brings to mind another medical prohibition that has caused suffering for some - not being allowed to use a Nicotine Patch (I think it's called). Some people use them to help to break the smoking habit, but Watchtower prohibited their use years ago, saying we must rely on "holy spirit" to give up tobacco.
Some could not break the habit and were disfellowshipped. There are some people who can't cope with being shunned and isolated which sometimes leads to suicide.
I doubt there is any way that deaths from banning the Nicotine Patch can be tracked, but it's another harmful Watchtower medical directive.
(Has this prohibition changed in recent years?)
