Driving with Medical Marijuana in Florida

Driving with Medical Marijuana
In Florida, registered medical marijuana patients are allowed to drive with medical marijuana products in their possession, but it is illegal to use or administer these products while in the vehicle. Despite medical marijuana being legal in Florida, it remains a Schedule I substance at the federal level, making it illegal to travel into another state with medical marijuana, even if that state has also legalized it. Law enforcement can only access the Medical Marijuana Use Registry to confirm that a person is a registered patient if they are investigating a violation of law regarding marijuana. There is currently no roadside test or technology that can prove that a person is driving under the influence of medical marijuana; instead, police officers rely on their observations of the driver's behavior.

Now that medical marijuana is legal in the state of Florida, thousands of residents have been able to find relief from a variety of medical conditions. However, given that recreational marijuana is still illegal in Florida and all forms of marijuana remain prohibited at the federal level, Florida residents have a lot of questions about the regulations surrounding treatment.

Things can get especially confusing for medical marijuana patients who are driving throughout or outside of the state, as the laws regarding driving with medical marijuana are not particularly well-known.

In fact, researchers at the Florida Survey Research Center at the University of Florida worked with the Florida Department of Highway Safety and Motor Vehicles to survey 693 Florida residents about their awareness of and opinions about marijuana-impaired driving. Over one-third of respondents admitted that they were “not at all knowledgeable” about legal issues related to marijuana use and driving. About half of the respondents claimed to be “somewhat knowledgeable.”

Unfortunately, having only some knowledge on the subject is not enough to make safe decisions about medical marijuana and driving. That’s why CannaMD has organized everything you need to know about driving with medical marijuana in Florida!

Florida Marijuana Laws

Medical marijuana became legal in the state of Florida with the passage of Amendment 2, which garnered support from over 71% of voters in 2016. Shortly afterwards, Senate Bill 8A was passed, which defined many of the regulations that pertain to the use of medical marijuana. These laws describe the conditions that can qualify a patient for medical marijuana treatment, as well as the process that must be completed before a patient can begin treatment.

Patients who suffer from a qualifying condition must visit a certified medical cannabis physician in order to receive a recommendation. The state then reviews this recommendation before allowing the patient to register for medical marijuana treatment. Once approved and registered, patients are able to purchase medication from a medical marijuana treatment center with a state-issued medical marijuana card.

Are You Allowed to Drive with Medical Marijuana?

If you are a registered medical marijuana patient, you are allowed to drive with medical marijuana products in your possession. This means if you are driving home from a medical marijuana dispensary or need to bring your treatment with you somewhere, you are legally allowed to do so.

However, you are not allowed to use or administer medical marijuana products in your vehicle. It is illegal to be under the influence of marijuana while driving, and using medical marijuana products in the car would violate this law. There are also additional restrictions on the use and transport of medical marijuana as defined by Florida law.

According to Senate Bill 8A, medical marijuana use and/or administration is strictly prohibited in the following places:

  • On any form of public transportation *
  • In any public place *
  • In the patient’s place of employment (unless permitted by his or her employer)
  • In a state correctional institution
  • On the grounds of a preschool, primary school, or secondary school
  • On a school bus
  • In a vehicle
  • In an aircraft
  • On a motorboat *

Low-THC cannabis use is permitted in categories followed by an asterisk (*). Low-THC cannabis is defined as:

A plant of the genus Cannabis, the dried flowers of which contain .8 percent or less of tetrahydrocannabinol (THC) and more than 10 percent of cannabidiol weight for weight.

Can You Smoke Marijuana In Your Car While Driving With a Medical Card?

While transporting legally purchased medical marijuana is legal (see above), consuming the product while in and/or operating a motorized vehicle is strictly prohibited – meaning: no, you you cannot smoke marijuana (even if it’s medical cannabis) while in your car and/or driving. As also mentioned earlier: Being impaired while driving is also illegal, even if the product you consumed was legally purchased.

Can I Drive with Medical Marijuana Between States?

Even though medical marijuana is legal in Florida, it is still classified as a Schedule I substance by the federal government. Given its Schedule I status, possession of marijuana is still federally illegal. Although many states have joined Florida in legalizing medical marijuana, federal law supersedes any laws that state governments have in place. This means that traveling into another state with medical marijuana, even if the state has legalized treatment, is illegal.

Allison Malsbury of Canna Law Group describes the practical risk of traveling between states with medical marijuana:

From a legal perspective, it’s very cut and dried. In practice, however, it’s very ambiguous. In practice, the chances of feds or the DEA sitting at the border waiting to catch someone – that’s just not happening. It’s not practical or worth their time.

However, as Americans for Safe Access reminds patients:

The best law enforcement encounter is the encounter that never occurs.

Can Police Access the Medical Marijuana Use Registry?

As with any medical treatment, privacy of medical marijuana records is a priority among patients. Since patients have to be added to the Medical Marijuana Use Registry, there is often concern regarding who can access this information. According to the Office of Medical Marijuana Use, police can only access the registry if they are are investigating a violation of law regarding marijuana in which the subject of the investigation claims an exception (the exception being that the subject is a registered medical marijuana patient):

Pursuant to s. 381.987, F.S. the department allows access to confidential and exempt information in the Medical Marijuana Use Registry to law enforcement agencies that are investigating a violation of law regarding marijuana in which the subject of the investigation claims an exception established under s. 381.986, F.S.

This essentially means that the police are only able to access the Medical Marijuana Use Registry to confirm that you are a registered patient. This may be necessary in the event that you are found in possession of medical marijuana products.

Probable Cause for Marijuana Searches

If you are driving with medical marijuana products, it is important to understand the laws that give police the right to search your vehicle. The Florida Highway Patrol Policy Manual outlines the rights of police members and the person they are interacting with. Importantly, Article I, Section 12 of the Florida Constitution protects persons and places from unreasonable searches and seizures.

However, with probable cause, police officers do have the right to search your vehicle:

Members may, with probable cause to believe the vehicle contains contraband or evidence of a crime, search said vehicle in any area or part where such contraband or evidence may be found.

According to the policy manual, probable cause means:

A fair probability that the evidence will be found, based on an objective assessment of the totality of the circumstances, viewed in light of the member’s training and experience. It means there is a reasonable basis for believing that a crime has been or is being committed, and showing that the items to be seized are at the place to be searched.

A police officer may also take action if medical marijuana products are in plain view. The policy manual states that:

Any time a member observes, in plain view, evidence of a crime or contraband, and the member has a lawful presence, the evidence or contraband shall be seized.

Plain view is defined as “observation of evidence of a crime or contraband, without searching, from a location where the member has a lawful right to be.”

Without probable cause or having medical marijuana in plain sight, police officers may also search your person or your vehicle if you give them permission:

Members may also search a person or a person’s property, including a vehicle, when that person orally gives that member permission to do so. For a person to consent to a search of a vehicle or other property, the person must own the property or have sufficient control of the property to authorize the search, such as the driver of a vehicle. This consent must be voluntary.

At any time the person can withdraw his/her consent to a search of his/her person and the search shall cease. Also, at any time, prior to establishing probable cause, the person can withdraw his/her consent to a search of his/her property, including a vehicle or any part thereof and the search shall cease. Any evidence or contraband found before the withdrawal of the consent shall be retained.

Specific consent to search the trunk of a vehicle or a locked container should be obtained.

Proving Marijuana-Impaired Driving

Currently, there is no roadside test or technology that can prove that you are driving under the influence of medical marijuana. Testing for THC in the body cannot prove impairment because it stays in the body for weeks, and can be easily challenged in court. Instead, if you are suspected of impairment, a police officer will have to rely on his or her observations of your behavior.

Police are training throughout the state to recognize signs of marijuana impairment, such as bloodshot eyes, sluggish reactions or difficulty multitasking. Observing officers will have to testify in court in order to make a case for impairment.

Luis Lopez, a retired Jacksonville Sheriff’s Office investigator, teaches police how to detect marijuana-impaired drivers. As Lopez explains:

We’re building a case. We’re not telling officers to look for one thing. That’s why the signs of impairment from the officer is so important.

Marijuana Smells & Police Searches

In the past, the smell of marijuana alone has been considered probable cause, enabling police to search suspicious vehicles. However, with the legalization of medical marijuana, this has become much more complicated. Many people across the country are now challenging the laws that result in officers searching vehicles based on smell.

In fact, a recent Supreme Court case in Vermont ruled that the smell of burnt marijuana is no longer justification for a police officer to search a person’s property. In Florida, the scent of marijuana is still considered probable cause, but this may be changing in the future thanks to recent court cases, new hemp legislation, and evolving views on medical cannabis.

Pushing this defense to its limit, Florida resident Victor Chavez – who was found with recreational marijuana hidden in his truck – is arguing that police violated his constitutional right against unlawful search and seizure as the arresting officers had no way of knowing that the marijuana smell that prompted their search wasn’t from medical products. Chavez is hoping to have the case completely dismissed.

However, cases like the one involving Chavez may soon become moot, as hemp legislation challenges conventional “sniff and search” procedure.

In July 2019, following new legislation that broadly legalized hemp (which smells very similar to marijuana), Palm Beach County State Attorney Dave Aronberg announced:

The odor of marijuana, by itself, is no longer probable cause for a search [in Palm Beach County]. This is true whether the odor is detected by an officer, or by a dog.

State Attorney Jack Campbell also wrote a letter to law enforcement agencies in his jurisdiction announcing that he will not authorize search warrants in cases where officers or police dogs smell marijuana because it could easily be hemp.

Patients are hopeful this policy will soon extend to the rest of the state.

What About Police K-9 searches?

A specific concern that some people may have in regards to driving with medical marijuana is the conundrum of police dogs trained to alert officers of the presence of cannabis. Unfortunately, the majority of these dogs have already been taught to sniff out cannabis in any form, and they certainly wouldn’t be able to tell the difference between legal and illegal marijuana. So what does this mean for Florida medical marijuana card-holders? Would the alerting of a police K-9 be enough probable cause to conduct a search of your vehicle?

The short answer is yes (for now). If a police K-9 alerts an officer that drugs may be present in the vehicle, this is enough probable cause in the state of Florida for the officer to then conduct a search. However, Florida law also states:

Where a driver is stopped for the commission of a traffic infraction, he or she may be subjected to a canine search of the exterior of the vehicle so long as it is done within the time required to issue a citation.

So basically, an officer can’t keep you waiting for a K-9 unit to arrive after they’ve already issued you a ticket. They can, however, keep you waiting if they have probable cause to believe that another crime has been committed in addition to whatever traffic violation they initially stopped you for.

Now for the good news!

With the recent changes in hemp-related legislation (detailed in the section above), many Florida officers have been instructed that the smell of marijuana is no longer probable cause for search of a vehicle. And it appears other states are following suit. Because marijuana and hemp smell identical, and dogs can’t tell the difference, both the Ohio Highway Patrol and the Columbus Division of Police are suspending marijuana-detection training for new police dogs to avoid complications with probable cause issues in court.

While the mandate isn’t statewide in Florida (yet), it appears K-9 searches for marijuana will soon be a thing of the past.

What Florida Lawyers Say

As previously mentioned, there is no test that can prove marijuana impairment. According to Florida lawyers Dolan Dobrinsky Rosenblum, LLP, the only way a police officer will be able to prove that you are under the influence is by the impairment of normal abilities and actions.

Drowsiness and impaired walking, talking or hearing can all be attributed to marijuana use. According to Florida Statutes Section 316.193, you can be found guilty of a DUI if you exhibit these behaviors while under the influence of medical marijuana.

Many prescription drugs cause similar side effects that can impair driving. These medications come with a warning to stop patients from driving while under the influence; medical marijuana patients need to be equally responsible about using medical cannabis.

How Much Weed Can You Carry With A Medical Card in Florida?

Florida medical marijuana physicians, such as those working through CannaMD, are responsible for setting milligram maximums for each patient, based on both the patient’s medical needs/history and state-issued milligram limits. While these limits are covered in detail in our earlier post, Milligram Caps: FL Issues New Marijuana Rules, a quick chart is provided below for reference:

Note: Patients may not be in possession of medical cannabis products in excess of their personal milligram limit (which is issued by their physician and may differ from the state’s limit).
