Well..since they claim boogers are made because of the collection of dust and lint..I wouldn't consider that healthy but I also don't think it's unhealthy. I think boogers, just like feces and urine is used to get rid of as much waste as possible..I wouldn't consume my own waste, that's why it was released from me..serves no purpose and definitely no good lol....well it might serve some purpose, but not going back into my body. So it might not be unhealthy to..try them but in today's society..that's not considered good hygiene .
