Disincentivizing taxes are usually very profitable, because they're targeting goods that are considered overly desired. Their effectiveness is not too clear, but it is commonly accepted that they do reduce consumption. For example, a recent study on soft drink taxes concluded that retailers absorbed half of the extra cost to keep consumption high.
An alternative income source might be luxury taxes. There are a number of luxuries where consumption correlates positively with price - but it would be politically difficult to implement a tax on extravagance.
