Ranchers typically own their ranches and are supported by a large staff which can include family members who work on the ranch. Ranching can be seen in parts of the United States, New Zealand, Australia, Argentina, and Brazil, where large expanses of land are available for ranching.
Like tobacco smoke, marijuana smoke contains cancer-causing chemicals. There are 33 cancer-causing chemicals contained in marijuana. Marijuana smoke also deposits tar into the lungs. In fact, when equal amounts of marijuana and tobacco are smoked, marijuana deposits four times as much tar into the lungs. This is because marijuana joints are un-filtered and often more deeply inhaled than cigarettes.
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.
