It's much more difficult than biosynthesis of alcohol, which is so easy you can do it by accident. Leave a container of fruit juice uncovered and wild yeast will most likely ferment it. If you add dried yeast and cover it with an airlock (which can be as simple as a lose snap-fit lid (snap-fit so it won't get stuck and explode)) and it will most likely taste acceptable too.
Fermenting alcohol is so easy that there's no practical way to enforce alcohol prohibition. It takes no specialized equipment (lights etc.), it's easy to hide, and you might be able to pass it off as an accident if you get caught. If you could make other drugs in the same way it would become very hard to enforce their prohibition.
