Yeah, they say it makes you stronger and, if I remember correctly, it gives you skin like iron, or something like that. Seems to raise strength and defense to me. And yeah, the guy smokes it with a pipe.
On a seperate note, it appears that some Roman gods might be used as drugs in the world of XIV. So far, we have Somnus and Pluto, one which makes you dream and the other which bolsters your physical body. Makes me wonder if others will appear later on.
