What’s the science behind love? That’s the question explored by Lucy Prebble’s The Effect, opening at Sydney Theatre Company on Thursday July 10 and continuing until Saturday August 16. The young Connie (played by Anna McGahan) signs up for a pharmaceutical drug trial to test the effects of a new antidepressant, and meets fellow volunteer Tristan (Mark Leonard Winter). As the doses increase, so does the attraction between the pair. But do their feelings come from the heart, or from the pills?

Prebble’s play won awards in London upon its debut in 2012, and its Sydney season is preceded by a run in Brisbane. Later this year, Melbourne Theatre Company will stage a production of its own. Meanwhile, we’re giving you the chance to let The Effect work its way to your heart, with a double pass up for grabs to each of the Tuesday July 15 and Wednesday July 16 shows. For the chance to win, head to the comments below and tell us why love is the drug for you.
