If so, what do you think might be the cause of it? Was Tasha Yar wrong in her explanation?
WESLEY: What I can't understand is why anyone would voluntarily become dependent on a chemical.
DATA: Voluntary addiction to drugs is a recurrent theme in many cultures.
TASHA: Wesley, no one wants to become dependent. That happens later.
WESLEY: But it does happen. So why do people start?
TASHA: On my home planet, there was so much poverty and violence, that for some the only escape was through drugs.
WESLEY: How can a chemical substance provide an escape?
TASHA: It doesn't, but it makes you think it does. You have to understand, drugs can make you feel good. They make you feel on top of the world. You're happy, sure of yourself, in control.
WESLEY: But it's artificial.
TASHA: It doesn't feel artificial until the drug wears off. Then you pay the price. Before you know it, you're taking the drug not to feel good, but to keep from feeling bad.
WESLEY: And that's the trap?
TASHA: All you care about is getting your next dosage. Nothing else matters.
WESLEY: I guess I just don't understand.
TASHA: Wesley, I hope you never do.
