Take two for relief of pleasure

In their study, 82 participants were randomised to receive either 1000mg of paracetamol (acetaminophen) or placebo.

After waiting 60 minutes for the drug to take effect, they were asked to rate 40 photographs on whether the image made them feel positive or negative.

The photographs ranged from extremely unpleasant, such as malnourished children, to neutral images, like a cow in a field, and very pleasant, such as children playing with kittens.

Compared to those who took the placebo, participants taking the pain killer reported weaker emotional responses toward both the pleasant and disturbing photos.
