This makes sense. Governments need money.
What would make even more sense is for lots of government officials to realize that if taxing alcohol can mean a boost in revenues, then legalizing and taxing not harmful yet still illegal drugs like marijuana could mean a massive boost in revenues.
Taxes are the obvious, but the reduction in spending on law enforcement and incarceration would make it a double boost. Just like prohibition increased crime and was a huge drain on society so too is the war on drugs, but we would rather moralize than be responsible.
