don't tell me about meth. but Why do they make sudafed and other medicine like it with and without? If you can draw from the same medicine without it, why do they construct it with?
Answers:    It acts as a decongestant by constricting the blood vessels contained by your nasal passages. It may also dilate bronchial tubes slightly.

You said "don't tell me about meth", but to be precise the main reason that drug companies started marketing decongestants without pseudoephedrine (so they could reasonably keep their product on the OTC shelf instead of behind the counter)--some people be stealing pseudoephedrine-containing products to produce meth.

Also, it can interfere with some blood pressure meds, so there were already some decongestants for ethnic group on those. Source(s): http://www.drugs.com/cdi/pseudoephedrine...
