I am sorry to have to disagree here.
I know Mr. Chong personally and know the story all too well, and it had nothing to do with
mailing things to or from Pennsylvania..his violation in selling by mail order would have been charged in any state he might have resided in at that time.
Besides having been a Pa. resident myself, I claim familiarity with the law, and the law for US mail is the same all over the US..
One USPS=One Law.
The only two exceptions are no pharmaceuticals may be ordered by mail in PA and
no wine may be shipped.
Period.
It is not illegal to buy or send glass to and from PA.
Please read the article for yourself, rather than allow others to harbor a false notion!

Tommy Chong just happened to live in Pittsburgh, when he broke a Federal Law.
It was in 2003 against Federal law in EVERY state to sell pipes advertised as "Pot Pipes".
Tommy Chongs Federal Charges had nothing to do with Pennsylvania, except for the fact that he went to Federal Court there , since it was his "Home Venue".
EDIT:
Just got off the phone with the Supervisor of the Local Tucson Post Office.
There are
no laws particular to what can be sent to the state of PA, outside of prescription drugs, and wine/liquor.
It is however illegal to own items sold, and labeled clearly as being made for Marijuana use.
The one law that differs in Pennsylvania from most other states where USPS is concerned
