@tboyer From what i’ve seen, i think yes it will affect snuff.
“Anyone born after 2008 will not be able to buy cigarettes or tobacco products in their lifetime” under a law expected to be enacted next year. ( BBC NEWS)
I’ve read that it won’t affect vaping, as vape juice doesn’t use tobacco, only nicotine itself ( plus a carrier such as propylene glycol or vegetable glycerine, plus flavours such as menthol, or edible liquid fruit flavours etc ). However, the quote said cigarettes or tobacco products,will be banned, and snuff is certainly one of those.
