Opium War

The Opium War was a way for the Westerners to get a foothold and territories in China back in the Ching Dynasty. They got the Chinese hooked on expensive and addictive opium, which not only drained the financial resources of the Chinese, but also kept a lot of them under the haze of drug addiction. As there were no drug treatment centers at that time, those who are hooked are eventually permanently hooked, unless a family member or friend would be able to withstand the intense suffering of the addict as he goes through his withdrawal symptoms.

People really don't learn from history's mistakes, and keep making the mistake of falling into the drug trap.
