The title of this episode is commonly known as 'Ecstacy'. This episode takes place in the summer of 1985, around the same time the United States made it illegal and classed it as a Schedule I narcotic. It was briefly removed as a Schedule I narcotic in 1987. Ecstacy was very popular in the 1990s at night raves. Also, it's worth to note that the therapists in this stated that MDMA is non-addictive. That's not entirely true. It can become addictive if not taken properly in higher doses and also causes dehydration to those taking it at higher doses. Also, MDMA was created in 1912 to treat urinary infection and the US Army attempted to use it in the 1950s as a truth serum (which failed.)
