“Just the Facts...” Empower your children and grandchildren by opening a dialogue with them about marijuana. What is marijuana? Marijuana generally refers to the dried, shredded leaves, stems, seeds, and flowers of the Cannabis Sativa plant. This mixture typically is green, brown, or gray in color and resembles the appearance of tobacco. The major mind-altering chemical in Cannabis is THC (delta-9-tetrahydrocannabinol). How long does marijuana stay in your body? The speed at which marijuana leaves your body depends on several factors including the speed of your metabolism, the potency of the THC, and the amount of marijuana you smoke. Most commonly, traces of marijuana can stay in your saliva for up to three days, urine for up to 30 days, and your hair for up to 90 days. Is marijuana addictive? Marijuana can be addictive. Not everyone who uses marijuana becomes addicted, but some users do develop signs of dependance. One study found that people who had used marijuana before the age of seventeen were more likely to use other drugs and develop addiction problems later on. by Pam Smith Reprinted by permission Amac Advantage Does driving under the influence of marijuana affect driving abilities?

Heavy marijuana use also has been linked with depression, anxiety, and personality disturbances. Marijuana is not always what it seems. Marijuana can be laced with substances such as PCP, formaldehyde, or codeine cough syrup without your knowledge. “Blunts” - hollowed-out cigars filled with marijuana - sometimes have crack cocaine added. Before You Risk It... Know the law Marijuana use is illegal for people under 21.
