probit: marginal effects

Hi,

I've got already the next question: In a Probit model for whether or not a household has any expenditure on tobacco would the following interpretation for the marginal effect (value = -0.1)of an independent variable "log of total expenditures" be correct? If total expenditures increase 1% the probability of that there are expendiutres on tobacco decreases 10%?

Thanks again!!
