Briefly explain how drug use, production, and sales pose a threat to public safety.

Drugs can prohibit dangerous behavior, and often result in actions consumers can't remember and/or have no control over. Such as vandalism, injury, threatening other victims, and even death. Making such drugs can be dangerous, as people may add or slip things into the drug of choice. 

Drug use, production, and sales pose a threat to public safety because they increase criminal activity as the desire to fulfill the addiction and make money through drug sales expands. Drug use also increases the spread of disease as individuals battling addictions often make poor judgments concerning sexual behavior, sharing needles, etc. Finally, drug distribution also increases the risk of pollution as chemicals needed to make drugs are dangerously mixed or used, creating an environmental hazard.
