The key distinction

Attention, memory, sleepiness, dizziness and low mood are not interchangeable. Withdrawal may overlap with poor sleep, stress, medicines or another health issue, so timing alone cannot assign a cause.

How to read the evidence

Temporarily simplifying demanding tasks, writing down the next step and taking planned breaks may help with day-to-day organization. Safety comes first when driving, operating equipment or doing work where reduced attention could harm someone.

What it means in practice

A sudden, severe, persistent or safety-affecting change needs prompt professional assessment rather than being assumed to be withdrawal. Local cessation support can also discuss the broader quitting plan.
