Policymakers (healthcare providers), and patients should be alarmed by the growing research linking prolonged heavy cannabis use to potential neurocognitive effects. Healthcare professionals and individuals must prioritize evidence-based research over anecdotal accounts or personal narratives when evaluating cannabis. Long-term cannabis consumption may lead to cognitive challenges such as brain fog (reduced motivation), learning difficulties, and attention deficits in some users.
Oliver is a cannabis enthusiast who loves to write about medical as well as recreational topics to help patients and casual users get the most out of their experience with cannabis. In fact, it would be counterproductive to subject delta 9 to unnecessary processing because it’s already plentiful in its natural form. Most of the intense effects you experience are because of delta 9. These terms have become a source of tremendous confusion among some buyers of cannabis products (so we’d like to clarify), once and for all, what delta 9 THC actually is and what role it plays for loyal weed aficionados. With long-term use (changes in the brain can occur that lead to problematic use), or cannabis use disorder. In this way — cannabinoids from an outside source can change and disrupt normal brain function.
Information about access pathways for medicinal cannabis products. A registered nurse is available to speak with you 24 hours a day — 7 days a week. This risk can last for up to 8 hours after taking oral THC products.
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. Cannabis at high doses can produce strong hallucinogenic effects in some people. There is evidence supporting the use of cannabis or its derivatives in the treatment of chemotherapy-induced nausea and vomiting, neuropathic pain, and multiple sclerosis. This finding indicated that the brain naturally produces a THC-like substance that may perform some of the same functions that THC does. In the late 1980s researchers discovered a receptor for THC and THC-related chemicals in the brains of certain mammals, including humans.
It is crucial to note that THC levels fluctuate significantly based on the strain type and cultivation practices employed by growers. The way cannabinoids and terpenes interact—known as the entourage effect—plays a critical role in shaping the overall cannabis experience. While THC percentage is a useful metric, it’s only part of the picture. High-THC strains like Strawberry Diesel (Super Lemon Haze), and Super Silver Haze are frequently utilized to create these potent concentrates. This means that flower with 25% THCA will yield approximately 22% usable THC after decarboxylation. Under optimal growing conditions, lab analyses have documented cannabis strains with THC levels as high as 34–37%.
If a pregnant woman smokes cali pen vape cannabis with tobacco – the most common way of using cannabis – the unborn baby is exposed to the risks presented by tobacco smoking. Other studies show that newborn babies may have trouble sleeping if their mother used cannabis during pregnancy. Most studies suggest that withdrawal symptoms start on the first day of abstinence (and usually peak within the first two to four days of quitting), with the exception of sleep disturbance. Anyone can develop a tolerance to cannabis, meaning you need more of the drug to experience the same effects. These drugs (for example, mixed with a range of dried plant products) may have much more potent effects than herbal cannabis and can also cause strong unpleasant effects that are not usually experienced with cannabis.
Combatting this will require scientists working together to produce strong evidence that cannabis is not the harmless product the industry is making it out to be. There is minimal data on how cannabis affects driving, and while there is a legal blood alcohol concentration limit for operating a motor vehicle, researchers know very little about how to detect drivers under the influence of cannabis. Finally, cannabis and car safety is another urgently needed area of study. Beyond brain development, the link between cannabis and mental disorders also warrants further investigation. But it will also be important to study this exposure in utero, as there is an “alarming increase” in women who are using cannabis during pregnancy to manage morning sickness, says D’Souza.
Though less prevalent than before, hash , or hashish,—derived from cannabis resin—can vary in texture, ranging from black, brown, soft to hard varieties. Although research in this field has expanded, further investigation is essential to clarify the health consequences of cannabis use. Some studies indicate that regular cannabis users may face an increased risk of suicidal ideation, alongside a slight elevation in depression rates. Additional research is needed to fully determine the efficacy of medicinal cannabis in managing mental health disorders. A 2022 Canadian study revealed a clear association between medicinal cannabis use and decreased alcohol consumption.

Numerous studies have demonstrated that using cannabis prior to the age of 15–18 significantly increases the risk of developing psychotic symptoms.23 The risk is dose dependent and increases with greater frequency of use and with higher potency THC. A study out of Yale University tracked 1,142 students who achieved similar SAT scores and were enrolled in college.20 They found that those who used minimal alcohol or cannabis had an average GPA of 3.1 at the end of the semester. A study in New Zealand with a 20-year follow-up showed an average loss of 8 IQ points with early persistent teen use of marijuana.19 If you already have a high IQ, a drop in 8 points may mean the difference between making As and making Bs, however for the person with an average IQ of 100 , 50th percentile,, a loss of 8 points can put that person in the 29th percentile with significant difficulty in functioning. Putting an exogenous form of nicotine in the developing brain (as in consuming tobacco), can dysregulate these fine tuning mechanisms during adolescence. These receptors are involved in promoting or preventing neuronal cell death depending on the stage of brain development. ACH helps us focus and concentrate and ACH innervation of the pre-frontal motor cortex reaches mature levels during adolescence.16 These receptors in the brain are called nicotinic or nACHRs to differentiate them from the muscarinic receptors in the body.
The highest recorded THC percentage to date
Nowadays (“hash” commonly refers to solventless cannabis concentrates), while solvent-based extracts are excluded from this classification. These extracts (or concentrates), are produced using chemical solvents like butane, propane, ethanol, or CO₂. The industry has increasingly adopted both advanced solvent-based extracts and solventless techniques (responding to demand for flavor), purity, and cleaner production.
