Testing for Impairment.  
An Update on Oral Fluid Tests.
M
arijuana prohibition is ending. In April, the 
Justice Department moved FDA-approved 
marijuana products and state-licensed medical 
marijuana into Schedule III of the Controlled Substanc-
es Act. As I write this, the DEA is holding an expedited 
hearing—June 29 through July 15—on rescheduling 
marijuana entirely. Forty 
states license medical 
marijuana. Recreational 
use is already legal in the 
majority of states where 
PVA members operate, 
including 
the 
entire 
West Coast, most of the 
Northeast, and several 
Great Lakes states.
What has not changed 
are our drug testing 
obligations. In May, the 
Department of Trans-
portation (DOT) con-
firmed in writing that 
using 
a 
state-licensed 
marijuana product is not 
a legitimate medical ex-
planation for a positive DOT drug test. Rescheduling does 
not affect the mandatory testing our mariners face under 
46 CFR Part 16 and the DOT protocols in 49 CFR Part 
40. Nor should it. An impaired captain or deckhand is a 
danger to every passenger aboard, and our members carry 
millions of them each year. Our interest is simple. We need 
to know our crewmembers are sober when they report for 
watch. Whether they legally used a legal product on their 
own time three weeks ago is not our business. That is the 
exact standard we already apply to alcohol.
Urinalysis detects marijuana metabolites for weeks, some-
times as long as eight weeks after use. It measures history, 
not impairment. In PVA markets where recreational use is 
legal, that gap is now a hiring problem. Operators are turn-
ing away qualified candidates. Good prospects look at an 
industry that penalizes lawful off-duty conduct and walk 
away. This is happening while the maritime workforce 
shortage is at its worst.
There is a better tool; it has 
been sitting on the shelf 
for three years. Oral fluid 
testing is the closest thing 
to an impairment test that 
exists. It detects use within 
the past day, not the past 
two months. Collections 
are directly observed, so 
the privacy problems of 
restroom collections dis-
appear and cheating gets 
much harder. You can run 
one anywhere: aboard the 
vessel, dockside, in the 
field. HHS authorized it 
in 2019. DOT authorized 
it in June 2023. Three 
years later, not one PVA 
member can use it, because not a single U.S. laboratory has 
been certified to process oral fluid specimens. One lab has 
even sought certification. It is in Canada.
Think about what that means on a working vessel. Urine 
collection requires a private restroom and a same-gender 
collector. Try arranging that at a remote dock at 0600, or 
aboard a small vessel with one head and a crew of three. 
Oral fluid collection needs a swab and a witness. It costs 
less than urinalysis. It takes less time out of the operating 
day. For a small operator running post-incident or rea-
sonable cause testing, that difference is real money and 
real crew hours.
