"How much of their income do low income families spend on cigarettes, alcohol, gambling, lottery tickets, illegal drugs?"

Lower-income households spend a disproportionately larger share of their tight budgets on these specific goods—frequently called "financial vices" or regressive products—compared to wealthier families.

Here is how the numbers break down based on economic and consumer research:Lottery Tickets
The Bottom Line: Lower-income households spend roughly 6% to 13% of their income on lottery tickets in heavy-use demographics, whereas high-income households typically spend less than 1%.

Poorest households can end up spending multiples more of their available cash chasing large jackpots in economic downturns, making the lottery functionally operate like a regressive tax.

Cigarettes and Tobacco; The Bottom Line: While overall participation is lower than expected, families living in poverty who do smoke dedicate a heavy chunk of cash to it. Studies on families in deep poverty show roughly one-sixth report buying cigarettes, averaging about $153 a month when active.

Low-income consumers show higher preference rates for tobacco products than higher-income brackets do relative to overall discretionary spending.

Alcohol; The Bottom Line: Expenditure data shows that only about one-fifth of families in poverty report spending money on alcohol, with a modest monthly average of around $24 for those specific consuming households.

Higher-income brackets generally spend more absolute dollars and have higher overall participation rates in drinking, but lower-income users feel the relative pinch on total cash flow much more severely.

Gambling and Casinos; The Bottom Line: Lower-income earners spend a larger percentage of their limited annual income on casino games and sports betting when they participate. Data indicates that roughly 11% of low-income vice spenders turn to debt or credit to fund gambling and substance habits.
Illegal Drugs; The Bottom Line: Exact official income-percentage statistics are difficult to track precisely through standard consumer expenditure surveys due to the illicit nature of the market. However, general data on recreational cannabis (where legal) and controlled substances show lower-income cohorts lean into alternative intoxicants similarly to tobacco, though national averages heavily skew based on individual addiction rather than broad household budget lines.
