Tranquilizers? Umm... That could be a lot of things. Wiki links to Sedative's http://en.wikipedia.org/wiki/Tranquilizers. They didn't have all the fancy new SSRI drugs that we have today. So it was more probably something good. Our drugs are way watered down compared to what they used to use. Like our .25mg dose of Xanax? (WTF is that gonna do?) Can we say placebo effect? Anyways, you wouldn't want to swallow these pills, they're way expired.
