I don't see this as one of the best episodes but it's still pretty good. Tod's behavior after taking the drug kind of reminds me of Frank Sinatra's character in a movie where he tries to kick the heroin habit. Sinatra's character is much more profound but his character still comes close to the one Milner plays here as Tod. I guess that this episode was very dramatic and realistic when it was shown back in 1961. The shock value is no longer there because this kind of problem has become so common in the US with much more lethal effects by more potent drugs. We're just too used to seeing and knowing about this kind of topic because society has been experimenting with all kinds of drugs ever since the early 60s. We've become desensitized. It stands to reason that the drug in this episode is LSD. It was a commonly prescribed medication in the late 40s. It's obvious after reading literature about LSD when it became popular in the US before it was made illegal. It was once legal to take as a recreational drug around the late 50s or early 60s. It started as an experimental drug at universities by the CIA in the mid 50s for mind control and chemical warfare, but it soon became popular among the young kids. Only after too many reports by police of nude people climbing trees and other drug induced behaviors did the government decide to make it illegal.
