I have to say that if it eventualy works out to be safe, why not.
Being brain damaged with epilepsy I had no help with the common drugs 20+ years ago. Then came Gabapentin, which was expieremental at the time. Seizures were affected to almost non existance. I was a guiny pig, and gladd for it. Now most epilepsy drugs are a darivitive of Gabapentin.
Aren't we all against "big tobbaco"
The situations are far from analogous. You were not receiving any benefit whatsoever from seizures.
Many people (whether they realize it or not) are using nicotine to self-medicate the symptoms of underlying conditions. Those who do realize it have noted that when they become abstinent from nicotine, their lives become unmanageable. In some cases this takes the form of an unspecified feeling of unease. Something's wrong, but you can't quite put your finger on it. In more severe cases, when they become abstinent they lose their ability to pay attention, focus, concentrate, remember. They sink into a deep, dark depression. They wait, and wait, and wait for these "temporary" problems to resolve themselves. But they don't resolve until nicotine use is resumed.
Now here is what will happen if the nicotine users described above have been vaccinated against nicotine. They will lose their ability to pay attention, focus, concentrate, remember. They will sink into a deep, dark depression. They will wait, and wait, and wait for these "temporary" problems to resolve themselves. But they don't resolve even when nicotine use is resumed, because the vaccination creates the antibodies that deactivate nicotine so that it doesn't do anything to relieve the symptoms.
To make the situation more analogous, let's say that Gabapentin worked to control your seizures, but it had the side effect of making your life unmanageable: You became unable to pay attention, focus, concentrate, and remember, and sank into a deep depression. But then suppose that you stopped taking it, but the side effects kept coming. Pretty bleak, eh?
Big
tobacco? No, Big Tobacco Control has taken over the role of telling lies and misleading the public.
