Fun fact! Drugs (at least pot) make you think you're more creative, but they don't actually make you more creative! It turns out, being inebriated just makes you more easily impressed by things
And then you never really figure it out because it fucks with your memory too, so you can never review all the amazing ideas you had after you've sobered up.
I mean, you are the authority on the matter after all.
I too enjoy pot and I agree, finding inspiration is one of the hardest parts of the creative process for me, so getting high makes it easier to start making cool stuff ..(or just make things like listening to music way better)
Try shrooms or LSD, but more so shrooms and see if you aren't left with perceptive changes to the world. Plus shrooms have a natural antidepressant effect that can last up to six months.
This is according to a few studies that have questionable methodologies, such as how they measure "creativity" but yeah, in general drugs only bring out what already exists in someone's personality. If you're a really creative person to begin with, drugs can shift your perspective, which can be useful. But it isn't magic smart people juice.
I don't know, some of my most interesting art pieces have come about when I've been stoned. My sober ones always lack a certain pizazz. I've read through that research article I think you're mentioning, the methodology seemed too small in scope to really capture a change in something intangible like creativity. I think a study that takes sober artists with zero drug experience, have them create something, spend a few months smoking weed, and then create something again would be more encompassing on THC's affects on creativity.
Also I'd be curious to see how stress relief and a good mood affects creativity as well. Sure some art comes from dark places, but I'd imagine its easier to be creative when you're in a good place mentally.
