Is it possible to be addicted to cannabis?

Absolutely: A person can become "addicted" to many different things. Gambling, sex, food, drugs and alcohol, are some of the main ones. If a person engages in a behavior which they know could potentially lead to dire consequences and the person continues to engage in the behavior, some experts call such a thing an addiction.

No: Dr. Passer is wrong. The word "addiction" has a defined and specific medical meaning. Cannabis is, according to the definition, not addictive. Dr. Passer uses the colloquial meaning, and as a doctor he should not. Even Time magazine uses the word incorrectly, so the misperception is pervasive and resistant to correction.

Not really: Marijuana, like many drugs, can potentially be habituating, where an individual may crave the product when off for a few days, but there is no true withdrawal when stopping, and the substance cannot be categorized as an opioid preparation, which can be associated with addiction.
