Blind person and psychedelics?

So I was having a smoke on my porch and a blind friend of mine walked past. I went and had a chat with him, not least as I could hear his cane from halfway down the street.

We discussed how he manages money and I have seen him do presentations etc, but as I turned and went into my room I thought

What would happen, and what would said individual see, if they were to ingest psychedelics?

Assuming this person is blind from birth and has no concept of colours. Only sounds, smells and experiences.

Headfuck. This is why I don't sleep.
