Avoid long-term use in people who have or are at risk of lung problems, such as asthma or byssinosis (a disease caused by breathing dust). Marijuana may cause bronchitis, coughing, lung cysts, phlegm, reduced lung density, and wheezing.
Best Answer: A compound is something made up of elements (ie not one pure element). The word compound means something made of a combination of things - like a compound sentence or a military compound (made up of several buildings). Elements are the basic substances that make up the universe and cannot be broken down into different substances. Compounds are composed of two or more elements that have bonded to form one substance In short: Elements - cannot be broken down and bond to form compounds Compounds - two or more elements that have bonded to form a unique substance
All of the elements can be found in the Periodic Table, listed by atomic number. A compound is a substance that has one or more elements in its composition. The compounds have a fixed ratio of atoms which are held together by chemical bonds, such as covalent, ionic or metallic. A compound can be broken down into individual elements using chemical reactions. Most compounds form naturally in order to reach stability, as not all elements in the periodic table are stable. What is the difference between a compound and a molecule? A molecule is formed when two or more atoms join together chemically.
