in terms of pipe screens ben88 you can give it a shot.
I haven't used pipe screens on other than the "funny tobacco" I used to smoke while a college student in a small metal pipe, those were fun times and suddenly "funny tobacco" is allowed in some states while they take away or try to demonize regular tobacco. However that might help, also michiganlover has a great recommendation on using a coin at the bottom, perhaps a nickel or penny?
my thoughts on "funny tobacco" now being allowed is that is makes one more docile and manageable in terms of just being able to herd masses of people around like sheep, while traditional tobacco tends to get one thinking and be more individualistic. A threat to collectivism it seems.
