3. Tasha Yar's Anti-Drug Speech From Symbiosis (1988)
Remember those 'special episodes' we talked about? Time to talk about drugs, kids! In Symbiosis, the crew encounters two groups of related aliens, one of which has gotten the other addicted to a drug using the mistaken belief that the addicts are suffering from a deadly disease. After Crusher watches two of the aliens shoot up and realizes that they're enjoying their treatment just a little too much, the crew discusses the situation, and this leads Wesley to wonder aloud, in the most contrived way, why anyone would willingly do drugs (since, of course, these aliens aren't). In swoops Tasha Yar to explain her own experience with drugs - and god, is it awful:This ridiculous speech ends with Wesley saying that he still doesn't understand, and Tasha saying that she hopes he never does. Don't worry, Tash - he won't. And since you'll be killed next week by an oil slick, you won't ever have to worry about it again. Wish we could say the same.
