Researchers found that when they gave study volunteers a batch of pot brownies, the effects were as one would expect.
The surprise came when they tested brownies laced with both THC (the active ingredient in marijuana) and CBD, a non-intoxicating extract of the marijuana plant: The combo brownies were substantially more impairing than those containing THC alone.
