A powerful drug cartel refers to a group or organization that is involved in producing, distributing and selling drugs on a large scale. This term often implies that such groups have significant influence over their territories through violence, corruption, and intimidation tactics. They are typically well-organized and operate globally, with the ability to smuggle vast amounts of narcotics across borders. The power of these cartels comes from their control over supply chains, access to weapons and resources, as well as their connections to corrupt officials or politicians who turn a blind eye to their activities in exchange for personal gain.
