What are the three most common substances of abuse among homeless individuals?

The three most common substances of abuse among homeless individuals includes alcohol, crack cocaine, and marijuana due to their widespread availability and social acceptability in many communities. Alcohol has historically been a significant substance of abuse among the homeless population as it is often cheaper and more accessible than illicit drugs. Crack cocaine, a cheaper form of cocaine that can be smoked, has a high potential for addiction and is commonly used in environments where individuals face severe socioeconomic challenges. Additionally, marijuana is also prevalent within this demographic, as it is increasingly legalized or decriminalized in many areas, making it easier to obtain.
