Is chewing tobacco allowed in hand and security luggage? if so how much

Sam, I suggest you ask your airline and the airport you arrive at about whether you can take chewing tobacco in your hand or checked luggage. There is no detailed requirement on how much you can take. However, you should follow the general rule, that is, reasonable quantities for personal use. By the way, the customs doesn't specify duty-paid price for chewing tobacco. It just mentions that the tax rate is 50 percent.
