I don't have access to specific statistics on the exact percentage of homeless individuals who are drug addicts and don't want to move into a house in Los Angeles (LA) and Seattle. Moreover, it's essential to recognize that homelessness is a complex issue influenced by a variety of factors, including mental health, substance abuse, lack of affordable housing, economic challenges, and more.
Homelessness is a multifaceted problem, and individuals experiencing homelessness can have diverse circumstances. Some may struggle with substance abuse, while others may be facing mental health challenges or financial hardships.
To understand the current situation, I recommend checking with reliable sources such as government agencies, non-profit organizations, or research institutes that focus on homelessness and public welfare. They may have up-to-date data and comprehensive studies on the characteristics and challenges faced by the homeless population in LA and Seattle.
