Everyone needs a 420, even the Alcoholics on Saint Patrick's Day. If they followed the traditional 420, they'd get stoned instead of smashed. Then again, there are probably those that don't even know what 420 stands for. Why not be the one to send them this card so maybe they will actually ask about its meaning. After all, the herb smokers have the green buds, the Saint Patrick day celebrators have the green clover... not much difference.
