A 2020 study found that higher doses of medical cannabis led to a decreased use of ADHD medication in adults. Products containing a higher concentration of CBD were linked to lower ADHD scores.
This means that CBD can interact with ADHD meds, decreasing their efficacy while providing more pronounced benefits. CBD may also interfere with the metabolism of Adderall. The potential side effects of interactions between CBD and Adderall may lead to decreased appetite.
It is usually safe to take CBD with amphetamine within the therapeutic dose; however, it’s always best to talk to your doctor.
