Sumner’s Opium Dependence
The North WaterLaudanum begins as relief and becomes a habit that shapes Sumner’s work, judgment, and isolation before Arctic deprivation forces him to endure without it.

A Chemical Escape

Relief in a Glass
Self-medication
Patrick Sumner secretly mixes medicine from the chemist’s order into rum and waits for its effect. The drug brings relief from memories of poverty, disgrace, and grief.
A fragile freedom
He tells himself that being free of his former life means he can become anything. The thought soon feels hollow, and chemical comfort replaces any settled answer.
A Planned Dose

Managing the Drug
Carefully measured use
Before going ashore, Sumner takes laudanum to make the evening bearable. He calibrates the dose to avoid obvious impairment, treating dependence as a manageable private routine.
Hidden vulnerability
His calculation helps him participate socially but also conceals how much the drug governs his comfort. Other men mistake his reserve for temperament rather than need.
Routine on the Ice

A Nightly Retreat
Habit deepens
After exhausting days on the ice, Sumner increasingly takes large evening doses. While others play cards, he retreats into altered memories and dissolved time.
Work and avoidance
The drug helps him endure the voyage but also postpones engagement with the crew and his own past. He begins treating the cabin as a private refuge from the living world.
Medicine Lost

Withdrawal Begins
Supply misplaced
In the confusion of evacuation, Sumner’s medicine chest is carried to the Hastings. He discovers the loss just as the camp is trapped by storm and shipwreck.
Body without relief
Restlessness, fever, and nausea intensify as he faces a night without his drug. The crisis strips away the illusion that his dependence is fully under his control.
A Body Without Laudanum

Survival After Dependence
No replacement available
At the mission, Sumner searches the medicine chest and discovers that its laudanum is gone. He reacts with anger, then continues eating and working without it.
A changed reliance
The absence does not resolve his inner conflicts, but he proves able to act and care for another patient while sober. His survival now depends on attention rather than chemical retreat.
