I still say Tasha's speech, however heavy handed it might seem to some, was the only time they really exploited her background of escaping from a failed Federation colony. Of course she'd be the one among the characters who has seen the most of drug abuse, and of course Wesley (a sheltered boy raised among Star fleet officers) would-be the most naive of it.
It's also the only time they touch upon the planned brother-sizter bond between Wesley and Yar.
Really, I have bigger problems with how the conflict in Symbiosis was resolved. Imho Picard made the worst possible decision that will lead to catastrophal fighting, death and suffering among the addicted population (that still thinks that it is dying AND that there is only a limited amount of "medicine" left)
Picard might have just sown the seeds for another world like Tasha's, that is if they don't destroy themselves completely in the fighting over the drugs.
The prime directive was broken the moment they rescued those people.
