Nasrallah dismissed them as attempts to tarnish the image of his resistance movement.
But the party's former secretary-general, Subhi Al-Tufayli, confirmed its involvement in the Lebanon drug trade in a television interview, along the lines of other groups in Iran's so-called Axis of Resistance, covering Iran, Iraq, and Syria.
Research published in The Christian Science Monitor in March 1988 also highlighted the involvement of all combatants in Lebanon in drug production and trafficking. The study even cited a Shiite cleric issuing a fatwa permitting the production and sale of opium and heroin to "enemies" under the justification, "If we can't kill them with weapons, let's kill them with drugs."
Project Cassandra
The party's involvement in drug trafficking was corroborated by global investigations, most notably Project Cassandra. This security initiative involved agencies from the US, France, Belgium, Germany, and Italy, among others, and uncovered Hezbollah's role in large-scale drug smuggling and money laundering operations across these countries, as detailed in the operation's reports.
Further investigations revealed Hezbollah's success in establishing a foothold for its illicit activities in Africa and the Americas, especially in Venezuela, the Guajira Peninsula, the Margarita Island, the Caribbean, and the Tri-Border Area among Paraguay, Argentina, and Brazil.
The party also operated in Panama, with confirmed links with the notorious Waked money laundering organisation and associated entities, such as Balboa Bank & Trust.
Hezbollah is also accused of exploiting the Al-Qard Al-Hasan Association as a front to manage its financial activities and access the international financial system. It was originally established as a charity offering interest-free loans in exchange for gold collateral.
However, the US Treasury imposed sanctions on the association in 2007, asserting that it facilitated the illicit transfer of funds through fake accounts and intermediaries, thereby exposing involved financial institutions to sanctions.
Hezbollah claims its funding sources are legitimate, citing its investment portfolios, donations from individuals, institutions, and businesses inside and outside Lebanon, and even Lebanese state funds.
Through its Waad Project, Hezbollah attracted a share of Arab aid allocated to Lebanon by requiring citizens to deposit their compensation into the party's financial system, which then oversaw the reconstruction of Beirut's southern suburbs after the 2006 war.
However, US historian Michael Rubin argued in an article published in National Security Journal in October 2024 that an increasing number of Lebanese view Hezbollah not only as a terrorist group but as a mafia-like entity.
According to Rubin, these sentiments aren't limited to Hezbollah; many Lebanese perceive their politicians – be they Shiite, Sunnite, Christian, or Druze – as mafias preoccupied with dividing spoils.
What sets Hezbollah apart, Rubin noted, is its militancy, which has helped it use dominance to get significant advantages, including tax exemptions and illicit revenues from customs duties, contraband, and smuggling activities at Beirut Port, Rafic Hariri International Airport, and border crossings.
This prompted Transparency International to rank Lebanon as more corrupt than Russia and Nigeria.
International response
On the global stage, an international consensus has emerged to counter Hezbollah's financial network. The US spearheaded these efforts.
In December 2015, Washington enacted the Hezbollah International Financing Prevention Act, which prohibited international funding for the group. The law imposed strict conditions on foreign financial institutions, barring them from maintaining correspondent accounts or payable-through accounts in the US if they facilitated Hezbollah's activities or dealt with individuals or entities listed as its affiliates.
