Did pirates during the Golden Age of Piracy smoke and what would they have smoked?
I'll assume you're talking about pirates in the Golden Age of Piracy, the 1690-1725 ones.
Pirates were mostly common sailors. Sailors of that era smoked. Smoking Tobacco by pipe had been established among sailors for roughly a century by that point. Sailors were some of the earliest Europeans to get into tobacco smoking via clay pipes. It could almost be argued that they were the first. You might want to explore this post more: Where does the stereotype of ship captains smoking pipes come from?. And that's all. And if you're asking about that particular kind of smoking, it's already been addressed a lot here. It's still no.
Although, of course, not all 17th century sailors were not pirates, smoking paraphernalia from this period is a regular find on many beaches. A casual walk down many beaches in England may yield remains of clay pipes from the 17th century or later (although dating such fragmentary finds is difficult), typically the 'stems' which are more likely to survive the hurly burly of the environment but sometimes other remains too.
