Your sole objective in posting here seems to be of a trolling nature,

I don't think The Dude is a troll, but Dude, answer this

Under Federal law, a state can NOT make food from another state
illegal, and if the person with the
food is travelling interstate, it falls under Federal law and not
state law.

yet you on a family vacation can go to a regular grocery store in
Appalachia, buy cans of food there, and when you get
into California, if a California cop catches you with those cans of
food you bought in Appalachia, you are now in very
very very serious legal trouble since California made a law declaring
that Appalachian food is illegal drugs, which
states can prohibit and make illegal under state law since Federal law
also prohibits and makes illegal drugs illegal.

You are now in very very very serious legal trouble for using illegal
drugs, and being a drug dealer, and being a drug
dealer who gave minors (your kids) illegal drugs. And contributing to
the delinquency of minors.

And now the Feds can arrest you for using illegal drugs since
California police records "prove" you did.

Did you break the law or not?

And heaven help the poor Appalachian family who actually eats some of
those cans of food in the next state right
before they get into California and then a California cop also gets
them on "traces of illegal drugs were found in
their blood".

Did that family break the law or not?

remember, under Federal law, states are NOT allowed to make food from
other states illegal.

But under Federal law, states ARE allowed to arrest people for using,
distributing, and even simply just having illegal
drugs.
