I think it is very risky since dogs at the airport can smell a pipe…..if you take your pipe, please soak and clean it with alcohol to it no longer has the cannabis residue but be aware of the laws in the state where you are traveling. It is against federal law to transport some paraphernalia. Back in Pres. Johnson’s term you could be sent to prison for 10 years for having any paraphernalia even a roach clip! Yeah have to know the laws to determine if it’s worth the risk in the risk is yours and the record is forever and can be quite damaging.
