Not rated, general health evidence
No pooled trials to rate. This rests on single studies, expert consensus or clinical practice. Measured in the general population; we say so because ADHD trials of this do not exist or are too small.

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.
