To learn more about the biochemistry of addiction, scientists in Australia dropped liquefied freebase cocaine on bees’ backs, so it entered the circulatory system and brain.
The scientists found that bees react much like humans do: cocaine alters their judgment, stimulates their behavior and makes them exaggeratedly enthusiastic about things that might not otherwise excite them.
What’s more, bees exhibit withdrawal symptoms. When a coked-up bee has to stop cold turkey, its score on a standard test of bee performance (learning to associate an odor with sugary syrup) plummets.
“What we have in the bee is a wonderfully simple system to see how brains react to a drug of abuse,” said Andrew B. Barron, a senior lecturer at Macquarie University in Australia and a co-leader in the bees-on-cocaine studies. “It may be that when we know that, we’ll be able to stop a brain reacting to a drug of abuse, and then we may be able to discover new ways to prevent abuse in humans.”
