An emerging body of international reporting and specialist research suggests Sierra Leone — a country rebuilding its economy and institutions — is at risk of becoming a destination for illicit drug money that is being channelled into property, business and political influence.
The phenomenon is not unique to Sierra Leone, but recent media investigations and regional studies show how transnational cocaine networks and the growing trade in synthetic drugs are exploiting governance gaps, porous maritime routes and weak financial controls across West Africa. 
In 2025 several international outlets published probing reports that a Dutch convicted cocaine trafficker, identified in reporting as Johannes “Jos” Leijdekkers, had spent time in Sierra Leone — raising concerns about how high-value traffickers establish footholds in coastal West African states. Those reports prompted official statements and an inquiry by Sierra Leonean authorities. 
Separately, local outlets and subsequent coverage flagged the arrest or investigation of other foreign nationals with alleged cartel links who were reported to possess or have used Sierra Leonean diplomatic documentation — allegations that prompted an internal probe by Sierra Leone’s immigration authorities.
Those reports have not yet resulted (publicly) in convictions; they do, however, highlight a worrying gap in vetting and passport controls. 
International studies and UN data show the broader picture: West Africa has become an attractive corridor for cocaine shipments bound for Europe, and with that flow comes large criminal profits that need to be laundered — often through real estate, vehicles and corporate investments.
Money launderers repeatedly use property purchases, front companies and high-value goods to convert cash into apparently legitimate assets. Those typologies are documented in recent UN and Global Initiative reports. 
Investigations in the region reveal recurring patterns:
- Real estate purchases and property development. High-value cash is channeled into land and housing in prime urban districts. In many West African capitals sudden jumps in prices in particular suburbs correlate with opaque foreign purchases and limited due diligence in conveyancing and land registration.
-
Where land administration is weak, ownership records can be obscured behind shell companies or locally registered nominees. - High-value consumer goods and vehicles. Luxury cars and imported goods can be bought with illicit cash, sometimes gifted or loaned to politically exposed persons (PEPs) to secure protection or influence.
Those assets are both status symbols and a way to integrate illicit actors into elite social circles. (This is a documented laundering modus in other jurisdictions; in Sierra Leone specific transactions have been reported anecdotally but require official forensic tracing.) 
- Business investments and hospitality. Shell companies, hotels and trading firms offer cover for cash flows and provide an appearance of legitimate income. In several West African investigations, hospitality and logistics businesses have been used as fronts for moving value and embedding foreign actors in local economies.
Where illicit proceeds arrive, they can translate into political leverage — directly or indirectly — through donations, patronage networks, and spending that raises the social profile of candidates. Investigative reporting in West Africa shows that criminal money can be spent to boost local campaigns or to build influence with officials who control regulatory and enforcement levers. In Sierra Leone, reporting that a high-profile European trafficker was present in the country has generated intense public concern about proximity between criminal actors and elites; that concern has led to calls for full, independent investigations. 
It is important to stress the difference between reported presence and proven collusion: journalists and civil-society groups have documented contacts and social appearances in some cases, but proof that specific officials accepted illicit funds or gifts requires financial forensics, property title searches and judicial processes. Responsible reporting must therefore identify links, demand investigation, but avoid unproven imputations. 
Sierra Leone is also confronting a deadly synthetic-drug crisis. The drug known locally as “kush” — a mixture that can include potent synthetic opioids and novel psychoactive substances — has devastated communities since its emergence.
Public-health and organised-crime specialists say kush’s precursors and chemicals often enter via maritime and import channels that are insufficiently monitored. Independent studies and NGO reporting have linked kush to a sharp rise in overdoses, psychiatric harm and deaths among young people. 
Experts point to a two-fold danger: the same porous routes and corruptible checkpoints that allow bulk cocaine consignments to transit may also allow precursor chemicals to enter the country, enabling local manufacture of synthetic products — which then fuels a domestic public-health emergency that disproportionately injures poorer youth. 
At present, the most robust claims concern (a) the documented presence or alleged presence of foreign traffickers in Sierra Leone, (b) industry-wide money-laundering typologies that match the patterns observers see on the ground, and (c) the documented public-health harms from kush. What remains to be established through formal inquiry is:
- forensic tracing of property titles and beneficial ownership to determine who truly owns high-value assets;
- bank transaction analysis and mutual legal assistance to trace cross-border fund flows;
- transparent disclosure and investigation of any state documents (including diplomatic passports) that may have been misused; and
- independent audits of high-value public procurement and customs clearance patterns at ports and quays.
