Bipolar and addiction

Around 60% of people with bipolar disorder experience addiction at some point — the highest rate of any mental-health condition. Alcohol, cocaine and cannabis are the most common. Stopping any of them without stable mood treatment risks a manic or depressive episode.

Key signs

  • Existing bipolar diagnosis (I or II)
  • Distinct periods of elevated, expansive or irritable mood
  • Depressive episodes lasting weeks
  • Using in the manic phase; using to lift the depressive phase
  • Rapid cycling, especially with stimulant use

The link to addiction

Cocaine, amphetamines and MDMA can trigger manic episodes. Alcohol worsens depressive episodes. Cannabis is associated with faster cycling and worse outcomes in bipolar I.

UK treatment pathway

Any rehab you consider must have a psychiatrist on the team who can manage mood stabilisers (lithium, sodium valproate, lamotrigine) alongside detox. Stopping mood stabilisers on admission is a red flag — check before booking.

FAQs

  • Will I need to stay on lithium during rehab?

    Yes, almost always. Any good UK rehab continues your prescribed mood stabiliser and asks the prescribing psychiatrist for continuity. Stopping lithium abruptly is dangerous — never do it without a psychiatrist's plan.

  • Can cocaine trigger bipolar?

    It can trigger mania in someone with underlying bipolar, and heavy stimulant use is often the reason a first manic episode is recognised. It doesn't create bipolar in someone without the vulnerability.

  • Is there NHS dual-diagnosis help for bipolar?

    Yes, through the community mental-health team — but coordination with addiction services varies wildly by trust. Private dual-diagnosis rehab is faster and integrated, if the budget is there.
