What is bob marley reffering to when he says "Mr Brown?" (if your famalier with it)?

Question

And who is Mr. Brown?..anyway

Answer 1

Guns N Roses does this too [Mr. Brownstone]

It's a type of drug.

Answer 2

Dont listen to this ignorance.

Mr. Brown is not a type of drug (atleast in the song)

Jamaican folklore, tales, and other stories are very confusing and hard to understand.

This is one of marley's songs that is very very hard to interpret, (like midnight ravers, or burnin & lootin)

It is likely simply someone from either kingston, or trenchtown from bobs youth.
