In Tradewinds Classic, the only thing that is considered contraband (and even if it is contraband, the Port Authority is very inconsistent about applying contraband law) is Magic Dust. Why is Magic Dust contraband? Answer The game takes place in the Orient starting from 1860s. Historically, the Second Opium Wars ended at this time. One of the main results of the Second Opium wars was the allowance of Opium to be sold from China. So what you're really selling when you buy/sell Magic Dust is Opium. As soon as you start transactions with Magic Dust, you automatically become a drug runner. You Bastard!
