How Much Do You Know About Marijuana?
Knowing about marijuana can help you recognize its use in others, so you can encourage them to seek treatment. Marijuana is a street drug made from the flowers, stems, seeds, and leaves of the hemp plant. It is usually smoked as a cigarette, in a pipe, or in a cigar casing in which the inner tobacco has been replaced with marijuana. 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 man-made chemicals resemble THC (synthetic cannabinoids), but are much stronger than THC. They are sometimes called "spice."
