On top of what Xzi said, the statement "drugs are very expensive to create" is INCREDIBLY conditional, and oftentimes false. Again,
I'll refer to insulin prices, which a study shows that if it weren't for an oligopoly that three companies have on the market (all of which reside in the U.S., by the way), diabetics could be paying nearly one tenth of what they pay a
month for a year's supply of insulin.
I'll challenge you to think "says who?" whenever you see something vaguely stating the synthesizing drugs is "expensive." The reason I say that is because these gigantic corporations have EXCELLENT PR teams that exist purely to make them look good.
