If someone experiences withdrawal symptoms when they stop taking a drug, what does this indicate about their relationship with the substance?

It indicates they have developed physical dependence, as their body has adapted to the presence of the substance.

How does physical dependence differ from psychological dependence in terms of what each involves?

Physical dependence involves physiological adaptation to a substance, whereas psychological dependence involves emotional or mental reliance on the rewarding effects of a substance or behaviour.

What is tolerance in the context of addiction?

The process by which repeated exposure to a substance leads to a diminished response, requiring increased amounts to achieve the same effect.

Why does a person with tolerance need to increase their substance intake over time?

Because repeated exposure diminishes the body's response to the substance, so larger amounts are required to achieve the same effect.
