At lower prescribed doses, it has been shown to ease anxiety, improve mood, and reduce the stress response. In Alzheimer’s disease, laboratory work has indicated cannabinoids could protect neurons from damage and reduce brain inflammation, with some early evidence for improvements in agitation and sleep. For chronic pain, there are a range of studies we can look at, but this systematic review does so for us. Thankfully (with medical and recreational cannabis legality slowly opening up at a global level), researchers are finally researchers now have greater freedom to study THC in depth.
Following an 1836–1840 travel in North Africa and the Middle East, French physician Jacques-Joseph Moreau wrote on the psychological effects of cannabis use; he founded the Paris’ Club des Hashischins in 1844. The earliest evidence of cannabis smoking has been found in the 2,500-year-old tombs of Jirzankal Cemetery in the Pamir Mountains in Western China, where cannabis residue were found in burners with charred pebbles possibly used during funeral rituals. This is based on the discovery of a basin containing cannabis in a shrine of the second millennium BC in Turkmenistan. It can be the most potent of the main cannabis products because of its high level of psychoactive compound per volume — which can vary depending on the plant’s mix of essential oils and psychoactive compounds.
The user frequently undergoes a mild euphoria, as psychological effects generally take precedence. Subject areas under Encyclopaedia Britannica’s editors are managed by those possessing extensive expertise, which may stem from years of relevant work experience or advanced academic study. A different study indicated that lower THC doses might alleviate anxiety in certain users — while higher doses may increase anxiety in others. Participants in a small study using CBD reported improvements in sleep and anxiety; however, further research with a larger sample size is necessary to validate these results. Research on CBD products revealed that over 25% had less CBD than what was indicated on their labels — with some also containing THC. There are three prevalent forms of THC: flowers or herbs, hash/hashish, and hash oil.
Key Differences Between Smoking Frequency and Vaping Frequency : buy cannabis uk
THC is detectable within seconds with buy cannabis uk inhalation and peak levels of THC occur after 3 to 10 minutes. The bioavailability of THC when smoking or inhaling is approximately 25%, with a range of 2% to 56% , although most commonly between 10–35%,. However while THC’s pharmacodynamic tolerance may limit the maximal effects of certain drugs (evidence suggests that this tolerance mitigates undesirable effects), thus enhancing the drug’s therapeutic window. The presence of these specialized cannabinoid receptors in the brain led researchers to the discovery of endocannabinoids, such as anandamide and 2-arachidonoyl glyceride (2-AG). citation needed The elimination half-life of the barbiturate pentobarbital has been found to increase by four hours when concomitantly administered with oral THC. Formal drug–drug interaction studies with THC have not been conducted and are limited.
Cannabinoid hyperemesis syndrome (CHS) is a severe condition seen in some chronic cannabis users where they have repeated bouts of uncontrollable vomiting for 24–48 hours. A 2014 review found that while cannabis use may be less harmful than alcohol use, the recommendation to substitute it for problematic drinking was premature without further study. Although the epidemiological association is robust, evidence to prove a causal relationship is lacking. Amygdala abnormalities are sometimes reported, although findings are inconsistent. Some users may experience an episode of acute psychosis (which usually abates after six hours), but in rare instances, heavy users may find the symptoms continuing for many days.
Is your heart influenced by smoking CBD?
Chronic pain relief is the most common reason why people seek medical cannabis. For example, researchers have found CBD can weaken THC’s anxiety-causing effects. Some research and anecdotal evidence indicate THC may be used to treat a range of medical conditions.
This article explains the science, safety, and how UK patients can access medical cannabis treatment Studies from 2024 and 2025 suggest that CBD (and THC) may influence inflammation, oxidative stress, and cell growth, but clinical evidence in humans is still limited. This guide examines the science, safety and access to medical cannabis treatments for acne in the UK. This updated guide explains how medical cannabis and CBD may support people living with sleep apnoea, what current research shows and how treatment works in the UK. All of our articles are written by medical cannabis experts (guided by strict sourcing guidelines), and reference peer-reviewed studies and credible academic research.
Acute intoxication may occasionally induce visual hallucinations, anxiety, depression, extreme variability of mood, paranoid reactions, and psychoses lasting four to six hours. One study compared medical marijuana, CBD, and a placebo (fake treatment) for treating anxiety in veterans with PTSD. Some studies suggest that CBD may help reduce anxiety-like behavior in animals. It can take minutes or hours to feel the effects of THC. 11-Hydroxy-THC appears to have a similar terminal half-life to that of THC, for instance 12 to 36 hours relative to 25 to 36 hours in one study.

He observes that both cannabis use and cannabis use disorders are prevalent among young people in the U.S. and around the world. Certain neurobiological impacts of cannabis use during adolescence, including diminished gray matter volume and altered neural connectivity, may continue into adulthood, even after cessation of use. Additionally — exposure to high-THC levels may lead to a reduction in gray matter volume within the prefrontal cortex, adversely affecting executive functions such as planning and impulse control.
Many studies report an elimination half-life of THC in the range of 20 to 30 hours. Research supports its effectiveness for spasticity and central pain in multiple sclerosis — though evidence for other neurological disorders is limited, and long-term high-dose exposure may carry uncertain toxicity risks.
