I agree with what @cracklingroses said. If you want to take drugs because you find that they help you with your art and make it fun to do cannabis and psychedelics are probably much better options in comparison to alcohol or prescription medications. It is important to note that psychedelics do require a bit of prep work before taking them (dosing, making you are in a good headspace, making sure you are in a safe setting, etc) and neither cannabis nor psychedelics should be don't if you or your family has a history of psychosis since they can cause it to onset. Still, they are less harmful alternatives that can give you a good creativity boost.
