Love Is the Drug (2006)

Jonah Brand (John Patrick Amedori) isn't necessarily the type of guy who would interest ultra-hot Sara Weller (Lizzy Caplan). But when she and her friends find out he works at a pharmacy, they charm him into their circle and gain his trust with manipulative fawning. Jonah knows he's playing with danger, but it's tough to resist the game. Daryl Hannah and D.J. Cotrona co-star in this grizzly tale of addiction and obsession.
