I don’t take pseudoephedrin products because of the cardiovascular risks. It causes heart palpitations and an increased risk of stroke.
The idea is not to buy them to use them... Or to buy them and use them. Whatever.
In a free society, we should be able to buy a legal product and use it—or not—the way we see fit, as long as that use is legal.
If you buy Sudafed and then throw it away, that should be your business and no one else’s; especially the government.
The buying of multiple boxes of Sudafed then becomes a citizen protest against over-reaching government.
