The legalization and decriminalization of marijuana has swept across the United States over the past decade — and Rhode Island is no exception. In May 2022, Rhode Island became the 19th state to legalize recreational marijuana for adults 21 and older with the passage of the Rhode Island Cannabis Act. While legalization has changed the legal landscape around marijuana possession and use, it has also intensified a critical public safety question: what happens when someone gets behind the wheel after using marijuana, and who is legally responsible when that decision leads to a Rhode Island car accident?
This is not a hypothetical concern. As marijuana use has become more widespread and more socially normalized, the number of drivers on Rhode Island roads who have recently used cannabis — or who are actively impaired by it — has grown substantially. Understanding both the science behind drugged driving and the legal remedies available to victims is essential for anyone injured by an impaired motorist.
If you or a loved one has been injured by an intoxicated, drunk, high, or otherwise drug-impaired driver in Rhode Island, contact a Rhode Island personal injury lawyer to discuss your legal options.
The Rise of Drugged Driving in America
Federal data collected over the past two decades illustrates a clear and troubling trend: more Americans are getting behind the wheel after using marijuana than ever before. The National Highway Traffic Safety Administration’s roadside survey data from the mid-2010s found that the percentage of nighttime weekend drivers testing positive for THC increased substantially compared to survey data from the previous decade — with cannabis use among drivers roughly doubling over that period. More recent NHTSA and state-level roadside surveys conducted after several waves of state legalization have continued to show elevated rates of THC-positive drivers, particularly in states — like Rhode Island — where recreational use is now legal for adults.
The Substance Abuse and Mental Health Services Administration’s National Survey on Drug Use and Health has similarly tracked millions of Americans aged 12 and older who report driving under the influence of an illicit drug within the past year. That survey has consistently found that men are considerably more likely than women to drive after using a mind-altering substance, and that drivers between the ages of 18 and 25 represent a disproportionate share of impaired drivers overall — a pattern that has remained fairly stable even as overall marijuana use has climbed.
International data tells a similar story. Australia’s National Drug Strategy Household Survey has tracked a comparable segment of the population reporting drug-impaired driving within the past year, with rates roughly paralleling those found in comparable U.S. national surveys. While specific percentages fluctuate from year to year and survey to survey, the overall trend across multiple countries points in the same direction: as drug use — particularly marijuana use — has become more normalized, so too has the willingness of some drivers to get behind the wheel while impaired.
(Given how quickly survey data in this area gets updated, readers and researchers should verify the most current NHTSA, SAMHSA, and Rhode Island Department of Health statistics directly, rather than relying solely on older published figures.)
Alcohol Remains More Dangerous Than Marijuana — But That Doesn’t Mean Marijuana Is Safe
One of the most consistent findings across traffic safety research is that alcohol impairment poses a substantially greater risk to public safety than marijuana impairment alone. Peer-reviewed studies — including research published in outlets such as the Canadian Journal of Public Health — have found that drivers with even moderate blood alcohol concentrations are several times more likely to have engaged in reckless or high-risk driving behavior prior to a crash compared to sober drivers or drivers who had used marijuana but not alcohol.
This finding is important, but it should not be mistaken for a suggestion that marijuana-impaired driving is safe. Cannabis use has been repeatedly shown to impair the specific cognitive and motor functions essential to safe driving: reaction time, divided attention, lane tracking, and the ability to respond to sudden, unexpected hazards. THC impairment is also considerably harder to measure and detect than alcohol impairment, since there is no reliable, universally accepted roadside test — like a breathalyzer — capable of precisely correlating THC blood levels with real-time impairment. This detection gap creates significant challenges both for law enforcement seeking to prosecute drugged driving and for injury victims seeking to prove impairment in a civil claim.
Compounding the danger further, many impaired driving incidents involve polydrug use — a driver under the combined influence of both alcohol and marijuana, or marijuana combined with prescription medication. Research has consistently shown that combining substances produces impairment effects greater than either substance alone, dramatically increasing crash risk.
A Real-World Example of the Legal Complexity Involved
The legal complexities surrounding drugged driving prosecutions were illustrated in a widely reported Massachusetts case in which a driver was charged with manslaughter after a fatal crash that killed a Massachusetts State Police trooper. Prosecutors alleged the driver had picked up marijuana from a medical marijuana dispensary shortly before the crash and was suspected of being under the influence of marijuana at the time. The driver’s defense attorney disputed the allegation, denying that his client was impaired by any drug at the time of the collision.
This case highlights a recurring challenge in drugged driving prosecutions and civil claims alike: unlike alcohol, where blood alcohol concentration provides an objective, scientifically established impairment threshold, marijuana impairment is far more difficult to prove with precision. THC can remain detectable in a person’s system for days or even weeks after use — long after any actual impairment has worn off — which complicates efforts to establish a clear, science-based link between THC presence and impairment at the specific moment of a crash. This is exactly why experienced legal counsel and, in many cases, accident reconstruction and toxicology experts are essential in building a strong drugged-driving injury claim.
Rhode Island’s Legal Framework for Drugged Driving
Rhode Island law prohibits operating a motor vehicle while under the influence of any intoxicating liquor, drug, toluene, or any controlled substance — including marijuana — to a degree that impairs the driver’s ability to operate the vehicle safely. Unlike some states that have adopted a strict “per se” THC limit (a specific nanogram threshold that automatically constitutes impairment, similar to a 0.08% blood alcohol limit), Rhode Island’s approach to marijuana-impaired driving generally relies on evidence of actual impairment — such as field sobriety test results, officer observations, driving behavior, and in some cases, drug recognition expert evaluations — rather than a single fixed numerical threshold.
This distinction matters significantly in both criminal DUI cases and civil injury claims. Without a simple, universally accepted numerical cutoff, proving marijuana impairment often requires a more comprehensive evidentiary picture: erratic driving patterns, admissions made at the scene, physical signs of impairment observed by police or witnesses, and toxicology results interpreted by a qualified expert.
Key Legal Considerations for Drugged Driving Accidents
Accidents caused by motorists impaired by drugs, alcohol, or a combination of both raise a number of important legal considerations for anyone injured in such a crash:
Impaired Judgment and Coordination
Both drugs and alcohol impair a driver’s judgment, coordination, and reaction time. This impairment can manifest as poor decision-making behind the wheel, difficulty maintaining a consistent lane position, delayed braking, and a diminished ability to respond appropriately to sudden hazards, such as a pedestrian stepping into the roadway or a vehicle stopping abruptly ahead.
Increased Crash Risk Across Multiple Accident Types
Impaired drivers are statistically more likely to be involved in a wide range of serious accidents, including head-on collisions, rear-end collisions, single-vehicle crashes, and accidents at intersections where quick judgment and reaction time are critical.
Criminal Consequences
Driving under the influence of drugs or alcohol remains illegal throughout Rhode Island and across the United States. A driver found to be impaired may face criminal DUI/DUID (driving under the influence of drugs) charges, resulting in fines, license suspension or revocation, mandatory substance abuse education, and — particularly in cases involving injury or death — potential imprisonment.
Civil Liability for Victims
Separate from any criminal case, an impaired driver can be held civilly liable for the injuries and damages they cause. Victims of drugged or drunk driving accidents in Rhode Island may pursue compensation through a civil personal injury claim, seeking recovery for:
- Medical expenses, both current and future
- Lost wages and diminished earning capacity
- Property damage
- Pain and suffering
- Emotional distress
In cases involving especially reckless conduct, punitive damages designed to punish and deter similarly dangerous behavior
Importantly, a criminal DUI conviction is not required in order to pursue a successful civil claim — the standard of proof in a civil case is lower than in a criminal prosecution, meaning a victim may be able to recover compensation even in situations where criminal charges were reduced, dismissed, or never filed at all.
Severity of Injuries and Fatalities
Accidents involving impaired drivers frequently result in serious injuries or fatalities, given the combination of delayed reaction time, poor judgment, and often higher rates of speed involved in these crashes. Victims may suffer broken bones, traumatic brain injuries, spinal cord injuries, internal injuries, or tragically, loss of life. These catastrophic injury cases often require substantial, long-term compensation to account for extensive medical treatment, rehabilitation, lost future income, and diminished quality of life.
Prevention Through Law Enforcement and Public Awareness
Preventing drugged and drunk driving accidents requires a combined effort between law enforcement and public education. Sobriety checkpoints, drug recognition expert training for officers, stricter penalties for impaired driving, and public awareness campaigns all play a role in reducing the frequency of these preventable crashes. As marijuana legalization continues to expand nationally, many states — including Rhode Island — have increased funding and training for drug recognition experts (DREs), specially trained officers capable of identifying signs of drug impairment beyond what standard field sobriety tests can detect.
Personal Responsibility and Prevention
Ultimately, preventing impaired driving accidents starts with personal responsibility. Individuals who choose to use alcohol or marijuana have numerous safe alternatives available to avoid driving while impaired, including designated drivers, rideshare services, taxis, and public transportation. For those struggling with substance use or addiction, seeking help through addiction treatment and counseling can address underlying issues and reduce the risk of future impaired driving incidents — both protecting the individual and the broader public.
Building a Drugged Driving Injury Claim in Rhode Island
If you’ve been injured by a driver you believe was under the influence of marijuana, alcohol, or another controlled substance, building a strong claim typically involves:
- Obtaining the police report, including any notations regarding suspected impairment, field sobriety test results, or drug recognition expert evaluations
- Preserving toxicology evidence, including blood or urine test results obtained by law enforcement or hospital staff
- Identifying witnesses who observed the at-fault driver’s behavior before or after the crash
- Securing surveillance or dashcam footage, if available, showing the driver’s conduct leading up to the collision
- Consulting with toxicology or accident reconstruction experts, particularly in marijuana-related cases where impairment is harder to establish through a single numerical threshold
- Pursuing all available insurance coverage, including the at-fault driver’s liability policy and, where applicable, your own underinsured motorist coverage if the impaired driver’s policy limits are insufficient to cover your damages
Why You Need an Experienced Rhode Island Personal Injury Attorney
Drugged driving cases — particularly those involving marijuana rather than alcohol — often present unique evidentiary challenges not found in more straightforward DUI cases. Because there is no simple roadside test capable of precisely measuring real-time THC impairment the way a breathalyzer measures blood alcohol content, insurance companies may attempt to dispute whether the driver was actually impaired at the time of the crash, even where marijuana use is confirmed through toxicology testing.
An experienced Rhode Island personal injury attorney can help by thoroughly investigating the circumstances of the crash, working with qualified experts to establish impairment, pursuing all available sources of compensation, and aggressively countering insurance company efforts to minimize or deny a legitimate claim.
