The health risks of cadmium are real, but they're mainly an issue if you're going to extract cadmimum from the joint afterwards, maybe by wearing soldered jewellery or by using a silver teapot or wine jug. If you're just brazing carbie tips and you have reasonable fume control while you've got it hot, then it's no problem.
Personally I worry about fumes from a fluoride flux more than I worry
about the cadmium.
