I can really only judge my creativity by the path that I have followed.
Short story:
Wake n bake with weed from 10-14 years of age. Many a hallucinogenic drugs from then to 18. Much too much smoking of coke til 19. Then I found a band that had possibilities. Even with what seemed like perfect management for my band, it inevitably fell apart. That was 25 years ago.
In between then and now, years of alcohol and twisted cocktails of broken dreams occurred.
To the point of whether drugs enhanced creativity or songwriting? I don't fucking know really. It didn't work out like I had planned though.
I feel more comfortable now recording others projects with perspective of 'not' being as high as I was when I was expecting to be a rock star of sort.
I suppose I never did enough nor became popular enough to be an icon of drug use?
We all learn from our mistakes. Drug use was a big one that fucked me. Whatever anyone uses as inspiration is up to them. I make no judgements there.
That being said, I know many that still use, and are making a living playing and recording. Every person has their own level of usage that makes them feel comfortable. Whether the drugs make them more creative or not, is not up to others to decide. Each individual makes that decision themselves. If it don't work, well we are there to judge them and tell them they suck right? lol!
I can say that I have recorded failed attempts of
tracks in
my studio due to drunk players. The stoned ones tend to be more on top of things, but the ones who actually show up to play, without medication are the ones who shine always.
