When and how to come off ADHD stimulants — first US consensus

Bottom line

The American Society of Clinical Psychopharmacology (ASCP) has issued the first major US clinical-society consensus on when to stopadult ADHD stimulants. Seven specific conditions where deprescribing may be appropriate; cannabis use alone, notably, doesn’t meet the bar. The default remains continuation when treatment is working — this statement legitimises the “should I still be on this?” conversation without recommending the answer.

The research

The ASCP task force ran a 2-round Delphi survey of 45 international psychopharmacology experts, paired with a focused literature review. Consensus — defined as 75% or more agreement — was reached on 10 of 11 statements. The seven conditions under which stimulant deprescribing may be appropriate:

• The original ADHD diagnosis is deemed incorrect on reevaluation
• Cognitive complaints have other more likely causes
• Cognitive benefits from the medication are absent
• The stimulant is making another medical or psychiatric condition worse
• Side effects exist that can’t be managed
• The medication is being misused
• There’s an untreated substance-use disorder other than cannabis

The single non-consensus result is itself informative: regular cannabis use alone fell just short of being agreed upon as an insufficient reason to deprescribe. Translation: most panellists felt cannabis use by itself is not enough to stop stimulants. Literature context: the evidence base on initiating and titrating stimulants is decades deep; the evidence on coming off them is thin enough that this consensus is the first formal-society statement on the question. Two things it explicitly is not — a tapering protocol (the statement is about indications, not mechanics) and a recommendation that adult ADHD patients should come off stimulants by default.

What this means

If you’re on stimulants and wondering whether you should still be, this is the document your prescriber should know about. Take it to the appointment. The seven indications give you concrete language for a conversation that has historically relied on the prescriber’s personal practice patterns. Equally useful as ruling-in criteria for staying on: if none of the seven applies to you and the treatment is working, you’re aligned with consensus by continuing.
