The simple idea
Don't think "user = addict." Picture a slider:

Most people who use something never slide all the way to dependence. What turns use into a disorder is: losing control over it, and keeping on even as it damages health, family, work, money, or the law.
Four words worth knowing
- Craving — a strong urge to use, often triggered by a place, person, or feeling (walking past the old bar → sudden "I want a drink").
- Tolerance — needing more to get the same effect (the body has adapted).
- Withdrawal — an unpleasant (sometimes dangerous) reaction when stopping — the body's adaptation is now exposed.
- Dependence — the longer‑term pattern: use becomes a top priority despite the harm.

The clue that changes the diagnosis: the timeline ⏱️
Substances can cause psychiatric symptoms — anxiety, depression, even psychosis. So the key question is always: did the symptoms start before, during, or after the substance use? Someone with hallucinations who uses stimulants may not have schizophrenia at all — the drug may be the cause.

- Why does the timeline between drug use and symptoms matter so much?
