Well you could always use these domains to help people lose weight
Why do you need ideas for?
The names are nice but most people dont want to set up something to help someone else, only self greed about making a few quid over peoples misery.
The smoking one if need be could be a mini site for giving up smoking with direct links for nictone products.
The drugs one a mini site about drug use, its not going to make money so hopefully your buying these out of the goodness of your heart and will try and help and give free advertising to drug clinics so they can come off drugs, stop committing crimes to feed their habbit.
