Pirate Drugs
The hardest drugs you can find all combined together and administered in a really sketchy way. Kinda like a jeffery, but way less legit. typically injected by balloons through an unsterile needle.
In Blackbeard's final battle, he was trippin so hard on pirate drugs that he was shot 17 times and kept fighting. He also killed nearly 300 thousand British and French sailors that day.
