Cannabis
But it’s one of the signs of cannabis (marijuana) use disorder, which can significantly impair your life. When you use marijuana products, your body and brain become used to THC , tetrahydrocannabinol,. CNN says study found cannabis could double heart attack risk – but did it? Activation of these receptors can lead to nausea and vomiting (which is why many pharmaceuticals used to treat nausea), like ondansetron, block 5-HT3A.
The information we have underscores the need for further study and high quality, scientific information about the safety and potential uses of CBD. For example, the agency has warned companies to stop selling CBD products they claim are intended to prevent, diagnose, treat, mitigate, or cure serious diseases such as cancer, Alzheimer’s disease, psychiatric disorders and diabetes. This priority includes making sure consumers know about products that put their health and safety at greatest risk (such as those claiming to prevent), diagnose, treat, mitigate, or cure serious diseases. A recent paper clearly highlights the huge gap between how many adults in the UK rely on illicit cannabis to help control the symptoms of their health conditions, compared to the numberlegally prescribed. Together, we want to make sure that anyone living with a brain tumour has access to compassionate, expert care through the most trusted medical cannabis clinic in the UK.
Medicinal cannabis is most often used for the treatment of chronic pain, including neuropathic pain (nerve pain). Medicinal cannabis is not recommended as a first-line treatment for any health condition in Australia. Medicinal cannabis is not considered a first line treatment. So whether it’s your first time smoking weed or you’re already giving Cheech and Chong a run for their money, take a moment to appreciate all the benefits that delta 9 has to offer. The cannabinoids found in hemp flowers and leaves will offer some therapeutic benefits, but they won’t give you a deep psychoactive experience. Marinol, Syndros, and Cesamet are treatment options for some kinds of anorexia.
Does smoking CBD affect your heart?
Though rarer, the thc pens cali following outlines the most severe cannabis side effects—and what actions to take if they occur. Below, you’ll find the most frequently reported cannabis side effects. A minority of research indicates that certain cannabis products — formulated with precise THC, CBD, and cannabinoid dosages, may aid specific applications. Consult your healthcare provider to explore available treatment choices. Two THC-derived medications are FDA-approved in the U.S. for medical use, specifically targeting chemotherapy-related symptoms like nausea and vomiting.

The study was observational, meaning it can’t prove that cannabis use causes cardiovascular problems – just that an association exists. Compared with people who never used cannabis, participants who did so once a week had a 3% higher risk of heart attack and a 5% higher risk of stroke during the four-year study period. Published in the Journal of the American Heart Association, the study analyzed data from nearly 435,000 adults ages 18 to 74.
There may be other side effects of cannabis that are not listed here. This makes it difficult to know whether a specific cannabis product will be helpful for treating or managing any medical condition. Since the amount of each chemical in a specific cannabis product or strain varies, the effects of cannabis also vary by batch and strain and how you use it. Each cannabinoid has its own unique effects in the body and brain. If you are having symptoms of a mental health problem, do not try to treat these symptoms on your own.
THC and the endocannabinoid system
Research from 2014 highlights the potential impact of cannabis on brain development when used during adolescence. There’s lots of conflicting research on this topic, and many of the existing studies have only looked at animals. Here’s a primer on some common strains and their potential effects.
A systematic review analyzed associations of high-concentration delta-9-tetrahydrocannabinol (THC) cannabis products with mental health outcomes. Potent cannabis products show risks for psychosis and addiction, but the full mental health picture is still murky. “Anyone who has had a bad experience (whether it’s psychological or biological), they should stay away from this drug,” she notes. David Dooks, a 51-year-old based in the Boston area turned to marijuana after an ankle surgery last year. Studies done on the medical benefits of pot usually involve very low doses of THC (says Monte), who adds that those doses “are far lower than what people are getting in a dispensary right now.”
If you spot the phrase “rapid onset” on THC drink labels, expect effects to kick in even sooner , anywhere between 15 to 20 minutes,. “Hybrids are crosses of genetics between indicas and sativas and offer a more balanced effect profile that is somewhere in the middle,” Kirk says. “The effects when consumed are a more sedating body high and are often higher in THC compared to classic sativas and contain calming, relaxing terpenes.” THC “is the molecule produced by the cannabis plant that is responsible for most of its euphoric and therapeutic effects,” says Dr. Shields. Given this inconsistency, use cannabis products containing THC , short for delta-9-tetrahydrocannabinol, where its use is legal.

A 1972 study gave up to 90 mg/kg of THC to dogs and monkeys without any lethal effects. THC is sometimes prescribed off-label to treat glaucoma — Crohn’s disease, and post-traumatic stress disorder (PTSD). THC is classified variably under international and US law — with medical use approved in multiple countries. Nabiximols (a botanical drug which contains THC), is used medically to treat symptoms of multiple sclerosis, including spasticity and neuropathic pain.
- A person consuming THC may experience some temporary side effects.
- Most research indicates withdrawal symptoms begin on the first day of abstinence, typically intensifying within two to four days—except for sleep disruptions, which may linger longer.
- This is because the effects of cannabis and the other drug can become stronger and produce more unpredictable effects than if they were used separately.
- This can result in altered perceptions or emotional shifts, changing how you feel or interpret sensations.
- Other long-term effects of smoking cannabis are similar to the effects of smoking tobacco.

Though far less psychoactive than THC (CBN still offers mild relaxation effects), unlike THCa, which is entirely non-psychoactive. THCa lacks intoxicating effects because it does not directly activate CB1 receptors in the brain. Emerging research suggests it may possess potent anti-inflammatory benefits, potentially aiding neuroprotective therapies for neurodegenerative disorders. The FDA advises pet owners to discuss suitable treatment options with their veterinarians. Symptoms may include altered alertness—often sleepiness (somnolence) but sometimes insomnia; digestive issues—usually diarrhea or reduced appetite, though abdominal discomfort or nausea can also occur; and mood changes, commonly irritability or agitation.
The short-term effects of cannabis can also vary based on your method of consumption. “Since starting my treatment plan with Releaf, I’m genuinely shocked at how well it has worked.”Chloe Durrington, Releaf patient It is important to seek medical advice before starting any new treatments. At Releaf, safeguards such as not prescribing products above 25% THC for under-25s or those with psychiatric risk factors are in place to keep treatment safe.
However, therapies like cognitive behavioral therapy or motivational enhancement therapy may be part of the treatment plan. Future studies should investigate the therapeutic potential of cannabis-derived compounds for various medical conditions. Extensive, long-term human trials are still needed to clarify cannabis’s enduring effects.

When administered by a specialist under controlled conditions, THC is generally deemed safe. This card serves as verification for employers (travel authorities), or law enforcement, providing reassurance and legal protection in everyday situations. Medical cannabis products differ from recreational use — being strictly regulated, lab-tested, prescribed by GMC-registered specialists, and dispensed by licensed pharmacies. NHS access remains highly restricted — so most THC-based prescriptions are obtained through private medical facilities. A 2020 clinical review — *“Cannabinoids and Their Therapeutic Applications in Mental Disorders,”* synthesized findings from dozens of studies on cannabinoids for depression, anxiety, and PTSD. These effects are believed to stem from THC’s ability to interact with anandamide at CB1 receptors in brain regions governing mood and emotional responses.
