What are psychoactive medications?

The term 'psychoactive' is used to describe any chemical substance that affects mood, perception or consciousness as a result of changes in the functioning of the nervous system (brain and spinal cord).

Some psychoactive substances are used to relieve suffering and pain, while others are used recreationally. This page only considers psychoactive substances that can be prescribed by a medical professional.

Can I participate in research if I am taking a psychoactive medication?

Your eligibility for participation will depend on several factors, including the type of medication you're taking, how long you've been taking it, and the reason you're taking it. In determining your eligibility, we may also ask you about what medications you've taken in the past even if you aren't using them anymore.
