Is the Theravada system one of direct realism?

Thoughts?

For reference (and fyi DMT is one of the most powerful hallucinogenic drugs on Earth):

Regarding their theory of sense perception and the nature of the cognitive object, the Theravāda Abhidhamma view is a kind of direct realism that says we do perceive external physical objects.
