Does anybody know what a dro is?

This is one of the more understandable parts of a recent Sean Paul song.

Don't know what a 'dro' is, but a 'drow' is a dark elf.

Denizens of Menzoberranzan and servants of Malekith the Accursed have nothing to do with my question!

I am pretty sure from listening to some rap songs. That it is the new hip way to say Weed.

Ok, but is it an abbreviation of something?

hydroponic

Hydro some weed growers use an all water system to grow weed. If done right some highly powerful stuff

I will now plead the fifth if anyone decides to ask how I know.

It never entered into my mind that dro would be an abbreviation for hydroponic!

I honestly never paired this technology with illicit marijuana production, but it seems to make sense.

Thanks for the translation.
