I don’t remember much or even when the movie came out, but I remember it was about vampires or something like that that could be cured with a white snake bite I also remember that there was a scene in which a guy put out a cigarette on the palm of a “vampire”, but he did not notice anything, because they do not feel pain and so on I think this is a 2000s movie or maybe a little later
Lair of the White Worm (1988)?
