The financial effects of alcoholism on the family members of addicts can be massive, but little is known about whether treatment for alcoholism reduces that financial burden. A study was conducted in this regard. A study of 48 German families reveals that after twelve months of treatment, family costs directly related to a family member’s alcoholism. Average costs attributable to alcoholism decreased from 20.2% to 4.3% of the total pre-tax family income. Among those 48 families, two of the largest family expenditures directly related to alcoholism was for alcoholic beverages (averaging €252.13/£197.51/$310.29 per month) and cigarettes (averaging €92.98/£72.83/$114.43 per month). Twelve months into treatment, those costs had reduced to €70.63 (£55.32, $86.92) and €64.21 (£50.29, $79.04) per month. Also, after twelve months of treatment, the average amount of time spent caring for the affected family member dropped from 32.2 hours per month to 8.2 hours per month. Using the minimum wage in Germany for employees in the nursing industry (€8.50 per hour), informal care provided by family members initially piled on an additional financial burden of €274.30 (£214.87, $337.66) per month, which reduced to €69.79 (£54.67, $85.88) per month after one year of treatment. Even in cases of relapse, treatment for alcoholism still reduced the financial burden on families, but only by €65.22 (£51.09, $80.26) per month on average.
