Detecting nasal snuff odors indoors versus out?

your nasel passages my be a bit small mate and it takes a lot of fresh air to get that up there i wudnt wurry about it tho its the same with me but with cigars i can nose exhale machine made cigars but carnt hand made cigars but i blame that down to the amount of snuff i use a use alot i get threw 2 or 3 tubs aweeks sometimes

So just keep doing what I'm doing, with the window open, and maybe sit by a fan to get it in there deeper?

Thanks for the reply
