CBD does NOT affect driving – but cannabis products with THC can affect ability for up to four hours, study finds
- Scientists Find CBD Does Not Affect Driving In One-Of-A-Kind Study
- Participants inhaled cannabis containing different mixtures of THC and CBD
- Those who inhaled cannabis primarily with CBD maintained control while driving
- Participants who ingested the mixture showed impairment on the road
According to a landmark study, cannabis that contains mainly cannabidiol (CBD) is not impaired while driving.
An Australian team conducted experiments with participants who traveled 100 km after inhaling cannabis containing different mixtures of tetrahydrocannabinol (THC) and CBD.
Cannabis products containing primary CBD did not impair driving, while cannabis containing THC, or a mixture of THC and CBD, caused slight impairment measured 40 minutes later, but not after four hours.
The researchers say their study should “ reassure people using CBD-only products that they are probably safer to drive, while helping patients using THC-dominant products understand the duration of impairment. ”

According to a landmark study, cannabis that contains mainly cannabidiol (CBD) is not impaired while driving.
The study was conducted by the Lambert Initiative for Cannabinoid Therapeutics at the University of Sydney and conducted at Maastricht University in the Netherlands.
Lead author Dr Thomas Arkell said: “ These results indicate for the first time that CBD, when given without THC, does not affect a subject’s ability to drive. This is great news for those who are using or considering treatment using CBD products.
CBD has taken the world by storm with its medicinal powers which treat a number of conditions such as epilepsy, anxiety, chronic pain, and addiction.
However, there are many products on the market that contain both THC and CBD, which led the Australian team to study the effects on driving.
Cannabis products containing primary CBD did not impair driving, while cannabis containing THC, or a mixture of THC and CBD, caused slight impairment measured 40 minutes later but not after four hours. .
“With the evolution of cannabis laws around the world, jurisdictions are grappling with the problem of cannabis-impaired driving,” said Dr. Arkell.
“These results provide vital information on the extent and duration of impairments caused by different types of cannabis.”
The researchers recruited 26 healthy participants for the study, who used four different types of cannabis in random order to vaporize on four different occasions.
Each volunteer was then asked to drive on public roads where their control was assessed by a current driver who had not inhaled cannabis.
Participants vaporized cannabis containing mostly THC, mostly CBD, THC and CBD in combination, or placebo cannabis (without active ingredients).
The amount of THC inhaled by the participants was sufficient to induce strong feelings of intoxication.
To test how different types of cannabis affect driving, participants took two one-hour road tests, starting at 40 minutes and four hours after inhaling vaporized cannabis.

Professor McGregor said: “ With rapidly changing attitudes towards medical and non-medical cannabis use, driving under the influence of cannabis is emerging as a significant and somewhat controversial public health issue. .
“ While some previous studies have looked at the effects of cannabis on driving, most have focused on smoked cannabis containing only THC (not CBD) and have not precisely quantified the duration of the drug. impairment.
“This is the first study to illustrate the lack of effects of CBD on driving and to also provide a clear indication of the duration of THC decay.
CAN CANNABIS OIL CURE CANCER?
Cannabis oil is currently illegal in the UK
A mother of two claimed in February that she cured her aggressive breast cancer by taking a drop of cannabis oil containing THC every day.
Dee Mani, 44, refused chemotherapy when diagnosed with triple negative breast cancer – considered the deadliest form – and instead opted to try the oil, which is illegal in the UK .
Doctors gave him the green light just five months after switching to the oil.
Despite his claims that it cured her of cancer, there is no evidence that cannabis, or any of its compounds, can treat cancer in humans, as research showing that the anti- Tumors of the drug were in petri dishes and in mice.
Dr Kat Arney, formerly of Cancer Research UK, said that while the results of the study were promising, cancer patients should not hope.
She previously said: “ We know that cannabinoids can have a range of different effects on cancer cells grown in laboratories and on animal tumors.
“But at the moment, there is no good evidence from clinical trials to prove that they can safely and effectively treat cancer in patients.”
Cannabis oil – which is different from CBD oil because it contains THC, the compound that gives users a “ high ” – is illegal under UK laws.
It influences the release and absorption of “feel-good” chemicals such as dopamine and serotonin.
Billy Caldwell, from Castlederg, Northern Ireland, made headlines last April when he became the first Briton to be prescribed on the NHS.
He got permission to use cannabis oil to treat his epilepsy earlier this year.
