How Much Do You Know About Marijuana?

Marijuana is a drug made from the flowers, stems, seeds, and leaves of the hemp plant. It is usually smoked as a cigarette or in pipes like a bong (water pipe). Marijuana also can be consumed by mixing with foods, brewing into a tea, or vaping in an e-cigarette device. The main active ingredient is a chemical called THC (tetrahydrocannabinol). Some artificial chemicals resemble THC (synthetic cannabinoids), but are much stronger than THC. They are sometimes called spice or K2.
