Verdict

Low risk, decreased effect

Both can dull each other's effects, so if one wears off before the other it's possible to overdose due to the lack of counteraction

Low risk of harm from the combination, but one substance is expected to blunt the other. Redosing to chase the missing effect is the usual way this turns dangerous.
