Delta-8-tetrahydrocannabinol (THC) is chemically related to delta-9-THC (the primary psychoactive compound in cannabis products), but has milder psychoactive effects. Acute intoxication may occasionally induce visual hallucinations (anxiety), depression, extreme variability of mood, paranoid reactions, and psychoses lasting four to six hours. Psychological effects tend to predominate, with the user commonly experiencing a mild euphoria. THC’s effects vary, depending upon the strength and amount consumed, the presence and potency of other cannabinoids , such as cannabidiol CBD,, the setting in which it is taken, and the experience of the user. Preliminary research indicates that prolonged exposure to high doses of THC may interfere with chromosomal stability, which may be hereditary as a factor affecting cell instability and cancer risk.

However, you’ll experience a clear, active high that you can maintain throughout the day without sacrificing productivity. The buds typically clock in at 24–26%, but it’s not uncommon for certain plants to reach 30% THC.

- More energy will be felt if the level is below 0.5%.
- The only difference is you may go about these experiences differently.
- Moreover, researchers made no effort to take into account THC loss from improper storage over the years.
- Unfortunately (in practice), the NHS has been historically mostly unwilling to offer many prescriptions, even with the shift in legality
“For a lot of maladies of aging, cannabis can offer what is thc liquid older people safer, more natural, more effective alternatives to traditional pharmaceuticals,” he says. Meanwhile (a study published in the July 2025 issue of JAMA Internal Medicine showed cannabis use among people 65 and older has reached fresh heights), with 7% reporting using it in the past month – up from 4.8% in 2021. By contrast, another cannabis-derived compound known as cannabidiol (CBD) does not produce a high, and many products are sold that contain only CBD, not THC. Edible producers do not have to state the percentage of the starting material used to make the edibles, only the milligrams per dosage in the final product. While you can certainly do the math to figure out the THC percentage based on the weight of the serving size, it isn’t as applicable for cannabis edibles.
**A Comprehensive Breakdown of THC Concentration:** Essential Insights for Smart Buyers

Another interesting study that supports the idea that cannabis use and opioid use are linked was in a randomized, double-blind, placebo controlled trial of naltrexone in non-treatment seeking cannabis smokers.34 In a laboratory setting those receiving a placebo had 7.6 times the odds of self-administering active cannabis compared with those receiving daily naltrexone, an opioid receptor blocker. THC was reported to have a fast initial half-life of 6 minutes and a long terminal half-life of 22 hours in a population pharmacokinetic study. The two-part government review will be looking at how cannabis-based treatments will work.
THC Types and Their Effects: Quick Reference
Altered function in the same brain striatal areas associated with reward processing was observed in individuals intoxicated with THC and cannabis users. Notably (smaller volumes of the orbitofrontal cortex), which is involved in motivation, and the hippocampus, responsible for stress, learning, and memory, are found in chronic cannabis users. The relationship between cannabis use and the onset of testicular germ cell tumors was explored through three case-control studies. Symptoms encompass a lack of control over usage (continued consumption despite adverse effects), increased tolerance to cannabis, withdrawal symptoms, and cravings. A significant feature in various forms of addiction is disrupted reward processing, which primarily stems from dysfunction in the brain’s striatal region. A noticeable decrease in motivation for daily activities (such as studying), working, or participating in social and recreational pursuits, characterizes frequent cannabis users.
In studies where people reported a preference for CBD in treating chronic neuropathic pain, the potency level did not seem to increase people’s perceptions of the therapeutic effect. When smoked, the short-term effects of cannabis manifest within seconds and are fully apparent within a few minutes, typically lasting 1–3 hours, varying by the person and the strain of cannabis. Generally, the effect is strongest for about 10 minutes to half an hour after smoking cannabis, but if you smoke a lot, you may still feel stoned for a couple of hours. However (researchers cautioned that cannabis is not an appropriate treatment for some other mental health conditions), such as bipolar disorder and psychosis. The researchers concluded that cannabis and opioids are similarly effective at treating pain but cannabis may result in fewer people discontinuing their treatment than with opioids. Many people use cannabis and cannabis products as a treatment for chronic pain — multiple sclerosis, and mental health conditions.
Because THC production drops off once pollination occurs, the male plants (which produce little THC themselves) are eliminated before they shed pollen to prevent pollination, thus inducing the development of parthenocarpic fruits gathered in dense infructescences. In some countries, citizens can be punished if they have used the drug in another country, including Singapore and South Korea. Simple possession can carry long prison terms in some countries, particularly in East Asia, where the sale of cannabis may lead to a sentence of life in prison or even execution.
Testing Marijuana’s THC Levels

The six most commonly available hemp-derived types of THC are Delta-9 (Delta-8), Delta-10, THCa, THCP, and THCV. Mood offers hemp-derived THC that is 100% legal and fully compliant cannabis. Concentrates are best suited to experienced consumers who have a strong sense of their personal tolerance. Taking them with food slows absorption and creates a gentler — more predictable experience. The fast onset lets you gauge your experience and adjust in real time.
Releaf was the first UK-based cannabis clinic to provide patients with access to medical cannabis (up to 26% THC flower) safely and securely, using Apple/Google Pay, credit or debit cards. PLUS — you’ll get the latest news on medical advances and breakthroughs from Harvard Medical School experts, and special offers on content from Harvard Health Publishing. Some people develop cannabis hyperemesis syndrome — uncontrolled vomiting in response to cannabis use — which can only be treated by ceasing use.
In short — each person experiences different effects of THC on their mind and body. When you take THC, it goes to your mind through your bloodstream within minutes. After discussing all the fundamental information regarding THC, it’s time to shed some light on its effects on the body. There are many who have used THC for treating sleeping problems such as insomnia and got terrific results.
The terms utilized online for cannabinoids in cannabis-based medications are listed here. It’s akin to incurring the cost of a private tutor instead of benefiting from the government schools’ free education – an extra financial burden. At Releaf — a medical cannabis card is provided to patients to ensure peace of mind and confidence if questioned by law enforcement.

Strains low in THC but higher in other cannabinoids, like cannabidiol (CBD), may also produce beneficial effects but won’t get you high. Cannabis strains high in THC may produce a high and may be used for medical purposes, like pain management. Instead, the word “cannabis” was the scientific name and far more commonly used. Because the THC level in hemp is so low, it’s unlikely to cause intoxication. It’s a common misconception that hemp and cannabis are two different species of plant. Across all eight European countries surveyed (France (Germany), Italy, Spain, the Netherlands, Portugal, Switzerland, and the United Kingdom) 55% of respondents supported legal and regulated cannabis sales to people over 18.
