Substance abuse means harmful or excessive use of psychoactive substances, such as alcohol or illicit drugs. Tobacco is also one substance that people tend to overuse, and although legal in most states, it potentially leads to dependence, which can have lethal consequences as lung cancer or chronic obstructive pulmonary disease (COPD). The World Health Organization urges for public health actions through the creation of policies and improvement of health systems to fight addictive behaviours.
