A GP can discuss drug problems and refer you to a local service
Why it matters
- General-population evidence shows recent cannabis use can impair attention, memory and coordination.
- A meta-analysis also found cannabis use disorder was more common in people with ADHD, though estimates varied a lot between settings.
- That's reason enough to talk it through with a clinician, but it doesn't prove cannabis permanently worsens ADHD in every person, or that feeling calmer shows it's treating ADHD.
How to do it
- Say how often you use cannabis, in what form, and what you hope it helps with.
- Mention memory problems, broken sleep or trouble controlling your use.
- Ask a clinician or drug-support service to assess you and talk through support options.
- Talk about cannabis alongside your prescribed medicines and other substances.
- This item does not recommend cannabis for ADHD and is not a plan for stopping without supervision.
Putting it into practice
In real life
- Tell the clinician if you use cannabis at night because you struggle to settle.
- Mention using more than you intended even if you also feel that it helps you relax.
Watch out for
- Common mistakeFeeling calmer and doing better are different outcomes. Tell the clinician about both.
- Common mistakeFear of being judged can mean leaving things out. Ask for a confidential conversation about your use.
