Do you lose weight if you are snusing/snuffing?

Maybe: Maybe you will but you're still at risk for oral, laryngeal, and esophageal cancers which if you get cancer will definitely help with the weight loss.

Not particularly: Nicotine does have some appetite suppressant effects, but it is not a weight loss product. People who become dependent on it do have a problem with eating more and gaining weight when they try to stop. It is not healthy and is associated with mouth, tongue and throat cancer. If you have a weight problem, proper diet with reduced calories and increased exercise remains the best way to lose weight.
