Grizzly and Skoal have a lower amount of nicotine than most dip products. If he really wants something less harsh than the rest, I suggest a product called Snus. It's not dip but it is similar. It doesn't buzz you as much as dip does but it is not as bad for you.
i started on snus then i moved to pouches now i do long cut. needless to say most people don't believe me when i say i'm a 18 year old girl who dips i prefer skoal peach but cope is too rough to start out on.
