Concentrates are frequently used in edibles (requiring the psychoactive compounds to pass through digestion), which can extend their duration significantly. Determining a precise average for weed concentrate effects proves challenging without identifying the specific type first. They also vary based on the cultivar (growing conditions), and extraction method. Currently, understanding that THC percentage reflects the total THC content in a product is essential. To clarify, we’ve thoroughly examined what THC percentage indicates and how it shapes the overall experience for users.
THC also produces the “high” people feel when they smoke marijuana or eat foods containing it. Medical marijuana (or medical cannabis), uses the cannabis plant or chemicals in it to treat symptoms or conditions. One study (for instance), found that, just like people, nematode worms dosed with cannabis get the munchies.
One study suggests that the type of edible affects the time it takes to feel the effect, with hard candies kicking in quicker. The feeling will typically wear off after about 2 hours. So far (most studies have focused on CBD and THC), but scientists are looking into the effects of other cannabinoids, too. Cannabis-based products come from the dried flowering tops (leaves), stems, and seeds of the Cannabis sativa (hemp) plant. “Delta-8 THC is intoxicating and can get you high, but it typically takes a larger dose to feel the same effects compared to the THC that is naturally found in the plant.” Hemp cannabis is legally defined as cannabis that produces less than 0.3% THC,” says Shields.
The most common forms of cannabis are inhaled , breathed in, or ingested (eaten or how long does a vape pen take to hit swallowed). Cannabinoids are the reason cannabis affects how your brain works and how your body reacts to using cannabis. Each cannabis plant contains natural chemicals that create the effects a person feels when using cannabis products. Historically — marijuana plants have been classified as Cannabis sativa or Cannabis indica based on their appearance and historical origins. But cannabis can be harmful in certain situations, forms, and doses.
Testing Marijuana’s THC Levels
More research is necessary to examine the effects of secondhand cannabis smoke. There is not much research into the effects of secondhand cannabis smoke. Many effects of smoking cannabis are short term, meaning that they last for only a short period. In one study, heart attack rates rose 25 percent while stroke increased 42 percent in people who used cannabis regularly. Cannabis use can also bring on delusions or paranoia — especially if it’s used daily. Without understanding of how cannabis helps with pain (it’s impossible to know if it’s the best remedy for the patient), she explains.
**What is the maximum legal THC dosage allowed in the UK? **
In reality, testing was based on samples taken from weak domestic crops rather than illegal imports. Today, liquid chromatography is used and offers far more accurate readings. For reference (researchers analyzed no more than 18 seizures a year in the 1970s; today), they average more than 1,000. As the drug was illegal everywhere, most of it came from other countries, such as Colombia. Although THC was first extracted from weed in 1942 — researchers did not synthesize the compound until 1965 in Raphael Mechoulam’s laboratory. These ancient peoples knew that marijuana provided them with a unique experience.
Overall (feelings of relaxation), elation, hunger, and a slowed perception of time are quite common; as are laughter and increased heart rate. Some of these aromatic molecules make the experience more cerebral, whereas others cause a more stoning effect. The effects vary between strains, and it’s believed that the terpene profile plays a significant role. If you’re like most cannabis smokers, the main benefit of THC is that it gets you high. Cannabinoids (simply enough), are compounds that affect endocannabinoid receptors in the body to produce varying effects.
One of the best benefits of THC is that it has incredible anti-inflammatory properties, which is very effective in treating a lot of diseases. They can be used to treat kind of problems, that’s why they are expanding their reach all over the world very rapidly. The most common form of medicinal cannabis with THC sold today is in the form of oil. This is one of the common questions that most people have in their minds.
Delta-9 tetrahydrocannabinol (THC) is one of those cannabinoids, and it’s the ingredient responsible for making you feel high. They have high lipophilicity and rapidly distribute in the brain (adipose tissue), and other organs. Pharmacokinetic data indicate that THC is detected in human breast milk in low to moderate concentrations.43-46 The long-term effects of THC on the developing infant brain are not clear. There are studies indicating that THC and CBD act on cytochrome P450 isoenzymes to affect the metabolism of various drugs. It rapidly distributes in the brain, adipose tissue, and other organs.18,35 CBD has low water solubility and absorption leads to variable pharmacokinetics if CBD is given in capsules.
Effects of cannabis use
THC also affects the brain’s white matter, reducing connectivity between brain regions crucial for coordinated cognitive processes. Researchers have identified key risks from high-THC exposure for adolescent brains. Exposure to high levels of THC during this critical period can have significant (lasting effects on brain structure), function, and behavior. The adolescent brain is particularly vulnerable to high-dose THC due to ongoing brain development — especially in the prefrontal cortex, which governs decision-making, impulse control, and emotional regulation. THC impairs motor coordination (reaction time), and judgment, increasing risks for motor-vehicle and other accidents, and higher THC doses cause more impairment.
- Lower back pain is a common condition that affects many patients across the UK.
- Research suggests that prolonged cannabis use may lower glutamate metabolite levels in the human brain, though evidence remains limited.
- It’s a common misconception that hemp and cannabis are two different species of plant.
- Unfortunately (at the moment), we can only post to the UK with the confidence that 99% of your order will be delivered; we do not have such confidence/infrastructure to post to other countries.
Kirk notes that while many edibles provide comparable effects (gummies tend to linger longer and induce a stronger sedative response due to extensive liver metabolism), often resulting in a pronounced “couch-lock” sensation. The impact of cannabis varies widely among individuals (influenced by mood), body weight, prior experience with the substance, and the specific form consumed. Initially, it will suggest which cannabis-based medicines could provide genuine medical and therapeutic advantages for patients. At present, there’s scarce scientific backing for the safety and efficacy of these oils in treating epilepsy, despite containing the same active compounds.
**Research on cannabis’ effects on cognitive function remains insufficient**
Delta-8, Delta-9, THCa (upon heating), Delta-10, and THCP all generate metabolites that standard testing methods can identify. Standard drug tests focus on detecting THC metabolites, as the body converts all common THC variants into analogous compounds. Of the widely available and dependably tested options — Delta-9 THC consistently delivers the most potent effects. Eating raw THCa without applying heat will not trigger any psychoactive response. Each cannabinoid possesses a unique molecular framework, resulting in distinct experiences.
Despite medical cannabis being legally accessible since November 2018 (roughly 1.77 million UK adults still self-prescribe with street cannabis), with fewer than 100,000 holding a valid medical prescription.

Upon inhalation, THC levels in the brain surpass those in the bloodstream. The plasma half-life of THC ranges from about one to three days in occasional users and extends to five to thirteen days in chronic users. Generally — inhalation yields a more potent psychoactive effect compared to ingestion. After inhalation (THC and its metabolites rapidly enter the bloodstream through the lungs), reaching peak concentration within six to ten minutes. For all users (whether light or heavy), inhaled THC’s bioavailability falls between 10% and 35%. Some individuals reported intense cravings and withdrawal symptoms—such as headaches — nausea, and vomiting—even a week after quitting. Many synthetic cannabinoids are modeled after natural THC structures from phytocannabinoids. Synthetic cannabinoids are lab-produced compounds designed to mimic the structure or function of endocannabinoids or plant-based cannabinoids.
