How did the opium wars affect the british?

The Opium War is a shameful blot of Britain's history. This is because the British traders were trying to force a negative item, or a drug to be precise, into China, who refused to accept it. The reason China decided to refuse it is because the Opium is making the citizens addicts, and therefore must be stopped. The British didn't take this as a lesson, but instead declared war on China for not accepting an item that shouldn't be sold in the first place. So, this concludes that the war was declared without much consideration and thinking. Thus, I belive that The Opium War is a shameful blot of Britain's history.
