Join scientists and sufferers as they probe the mysteries of addiction. Doctors are discovering that addiction is not merely a lack of willpower; drug abuse produces significant chemical changes in the brain — changes that are hard to control, and hard to reverse. What’s worse, many addictions start with prescription or even over-the-counter pain killers for entirely legitimate ailments. And it is not just drugs — alcohol, sugar, caffeine, even exercise can incite addictive behaviours.
