Hash oil comes from cannabis plants and contains THC (delta-9-tetrahydrocannabinol), the same active ingredient as other marijuana products. Marijuana concentrates, including hash oil, are potent extracts from cannabis plants.
The products available vary in form. The table below outlines some common forms of hash oil. Since hash oil is more potent than other forms of marijuana, its effects tend to be stronger as well.
