Going a bit serious.

What is there about alcohol or marijuana (two very different substances, each producing different effects when ingested), that improves a person, whether it be their creativity, their stamina, their attentiveness?

For most, these are a choice, although alcohol can also become an addiction.

If one already has issues within themselves, like low self-esteem, various anxieties, etc, I can see how substances may help them feel more at ease with themselves.

I also can see where marijuana can be used for pain relief, and some other medicinal reasons. There are also CBD treatments that may be as effective.

No, I'm not arguing there is no reason for becoming intoxicated - but is there, really?

I'd say I'm personally pretty conflicted on this.
