Increasing numbers of states are legalizing marijuana, but it's still against federal law.

Trucking is caught between a rock and a hard place when it comes to marijuana, between public opinion and increasingly liberal state laws on cannabis use on one hand, and a federal government that classifies marijuana as one of the most dangerous illegal drugs on the other.

Marijuana advocates have been very successful in getting states to legalize cannabis use, said Abigail Potter, ATA’s self-described “drug czar,” in an educational session Oct. 27 during the American Trucking Associations’ Management Conference & Exhibition in Austin, Texas. Already, 31 states and the District of Columbia have medical marijuana laws on the books. There are 13 that have decriminalized possession, which focuses on reducing fines and jail time for small amounts of marijuana. And nine states and DC have legalized marijuana for recreational use; regulating it and taxing it brings in needed revenue.

One of those states is Colorado. Greg Fulton, president of the Colorado Motor Carriers Association, said the state has brought in millions and millions of dollars in tax revenue. The state previously had legalized medical marijuana, but Fulton said the industry was surprised when the recreational law passed – and that the impact was more than they had expected. After all, he said, it was evident that a lot of people were getting marijuana prescriptions for medical use. “Little did we know how much pain our young people were in,” he said, tongue in cheek.

Meanwhile, Canada just this month became only the second country in the world to make recreational use of marijuana legal. Jonathan Blackham, director of policy and affairs for the Canadian Trucking Alliance and Ontario Trucking Association, said his group “pushed back” during the process of writing the actual regulations to address highway safety concerns, but there are still a lot of unknowns.

Because marijuana is a Schedule 1 controlled substance on the federal level, however, truck drivers are not allowed to use it; nor are trucking companies allowed to transport it.

Some of the areas of concern that the panel outlined were:

  • A recent study by the Insurance Institute for Highway Safety and the Highway Loss Data Institute found that in the first states to legalize the sale of recreational marijuana, there has been a 5.2% increase in crashes.
  • There’s no clear process at this point for how to measure driver impairment, as there is with alcohol. “We are transportation safety people; we want that kind of standard,” Potter said. Blackham said after the industry and highway safety groups pushing the issue, Canada scrambled and approved a portable device that tests oral fluids which could be used by enforcement, the Drager 5000, but he said few enforcement officials have it yet so it’s unclear how well that will work.
  • There are no neat charts showing how much alcohol’s in a glass of wine or a cocktail. In fact, the amount of THC in different strains of marijuana can vary greatly, a problem made more difficult by the growth of “edibles” for those who would prefer to eat their pot than smoke it.
  • In an industry facing a driver shortage, legal use of cannabis may cut into the available driver pool. Some drivers could even consume edible cannabis unawares and fail a pre-employment drug test. One Colorado fleet, Fulton said, tells people who re looking for a job to not even bother to apply if they have partaken of cannabis within a certain period of time – yet still was getting a 60% failure rate on its pre employment drug testing.
  • In Colorado, dispensaries and grow houses tend to be located by zoning and other factors in the same areas that trucking companies are. Because of the increased demand, the price of real estate for terminals and warehouses has doubled and even tripled.
  • When it comes to medical marijuana, companies need to be aware of potential implications under the Americans with Disabilities Act. Some states that have legalized marijuana for medical uses specifically say in their laws that employers do not have to make accommodations, but others are the opposite, and some are silent on the issue.
  • Companies in states with legalized marijuana need to make sure they have clear company policies regarding its use, but those policies are all over the map. For some, it’s basically, “don’t come to work stoned.” For others, there may be zero-tolerance policies.

Meanwhile, it’s likely the trend toward legalization will only continue. Potter pointed to a Pew Research Center poll released earlier in the month showing a huge shift over the past decade. Today, 62% of Americans support full legalization of marijuana. Younger Americans are even more supportive, with 74% of Millennials approving of legalization. Legalization and medical marijuana referendums are on the November ballot in several states.

Potter said at some point, it’s likely the federal government may move marijuana to a less-restricted category in the controlled substances list.

While the National Highway Traffic Safety Administration is focused on finding ways to identify people who are driving while impaired by marijuana, “I think the challenge is we want to prevent that person from getting behind the wheel in the first place. With alcohol it’s not under the influence is not our standard; you are out of service at .04, you are not allowed to drive at .02. As an organization, we need to start thinking about what are those levels.”
