This has been beaten to death over the years and I believe the verdict from resident legal experts like
@Len-2A Training, is that no state issues a license/permit that follows those requirements (specifically the drug part)?
Yep, the drug part.
(Not even
Massachusetts qualifies, LOL).
Still, to the incredibly slight degree that "the best defense is a good offense"
during a traffic stop where the officer suspects you're in possession of guns
without a license, that EMail is at least a fig leaf. After all...
If you can't dazzle them with brilliance,
baffle them with bullshit.

However, you're doing the competitors a profound disservice
if you don't include a
separate cover letter that says...
... keep everything locked up and anything gun related out of sight in the event you get pulled over.
(^This.)
...and
do not flash that competition registration letter
until/unless you're discovered with guns.
Because when the cop asks "where are you going?"
when no guns have even been mentioned,
if they run their mouth about a shooting contest
because they think your letter gives them have a safe harbor,
then they're going to wish they'd just leapt from their car
while reaching for a firearm training card in their wallet,
while proudly screaming, "I have a gun and I know how to use it!".
At least in the latter case the cop might put them out of their misery.
Mentioning that letter in less than the gravest extreme
is going to dog them for the rest of their lives.
I wonder whether NES's Mass. firearms attorneys would even
want
a client in that jam to show the letter,
as opposed to saving it for the defense during trial...
