The way in which brain cells communicate with one another is influenced by both. In the U.S., finding CBD is less difficult compared to THC, although different laws and regulations regarding CBD sales exist in each state. Three typical forms of THC include flowers or herbs (hashish), and hash oil.
This weed strain is 90% sativa and contains about 18%-26% THC. Users of Blue Dream often describe it as energizing and uplifting, assisting them in managing conditions such as depression, anxiety, cali weed chronic pain, and PTSD. Many weed users like its sweet and peppery flavor profile. While sativa strains are frequently associated with energy — not every sativa strain has this stimulating effect. Tall height and narrow leaves define the characteristics of the sativa weed strain. The “high” sensation experienced when using cannabis is due to its psychoactive properties.
Cannabis can cause altered time perception — and impaired thinking, memory, and body movement. Synthetic cannabinoids (which are lab-made substances that are chemically similar to compounds found in the cannabis plant), can produce serious negative health effects.10 These products — which are also known as Spice or K2, may have a much higher concentration of THC and can be much more powerful. Between 1995 and 2022 the delta-9 THC potency , strength, in illegal cannabis products seized by law enforcement quadrupled from 3.96% to 16.14%. People commonly use cannabis by smoking dried plant material (“buds” or “herb”) in joints like a cigarette — in blunts—cigars or cigar wrappers that have been partly or completely refilled with cannabis—or in pipes or bongs (water pipes). Unless mentioned otherwise, the information on this webpage is only about cannabis products containing intoxicating amounts of delta-9 THC.
This includes cannabis products intended for medical usage unless they have been prescribed to you. Personal information, including your name and address, as well as the prescribing physician’s name and contact information, should be included in the letter. The functioning of your liver can also be influenced by CBD, requiring regular monitoring by your physician. Should you experience any adverse effects from medical cannabis, it is important to inform your healthcare team. CBD-only products — like Epidyolex, do not present the same unknown risks that are associated with THC.
Possible side effects can include drowsiness — light-headedness, alterations in appetite, digestive discomfort, and impacts on the processing of other medications.
According to a review article co-authored by Dr. Ethan Russo — MD, broadly speaking, 2.5mg of THC is a good starting dose for inexperienced cannabis users. In some countries marijuana is fully legal and accessible, and in others you can go to prison for possession of tiny amounts. Outside of the US, different countries have their own approach to cannabis. Despite advancements in research, evidence regarding the health effects of cannabis use remains elusive and there is no consensus within the medical community about which conditions it can treat.5
The endocannabinoid system is influenced by CBD in a more indirect manner, also affecting various other receptor systems within the body. This explains why raw marijuana typically does not result in the same intoxicating effects as marijuana that is smoked, vaped, or cooked. The aging of cannabis can result in this process occurring gradually over time, though exposure to heat greatly accelerates it. The activation of CB1 receptors in brain regions tied to pleasure (memory), movement, sensory processing, and the perception of time is what causes THC to induce a high. By binding to these receptors, THC is able to produce significant physical and mental effects associated with marijuana.
The European Monitoring Centre for Drugs and Drug Addiction reports that typical retail prices in Europe for cannabis varied from €2 to €20 per gram in 2008, with a majority of European countries reporting prices in the range €4–10. The main producing countries of cannabis are Afghanistan (Canada), China, Colombia, India, Jamaica, Lebanon, Mexico, Morocco, the Netherlands, Pakistan, Paraguay, Spain, Thailand, Turkey, the United Kingdom, and the United States. “Skunk” refers to several named strains of potent cannabis, grown through selective breeding and sometimes hydroponics. In some countries (citizens can be punished if they have used the drug in another country), including Singapore and South Korea.
The illegal status of cannabis in numerous countries may deter individuals from participating in research — and those who do may not fully disclose their cannabis usage. Researchers face challenges in enlisting cannabis users for their studies. Conducting cannabis research is difficult due to the plant’s illegal status in most nations. It indicates that certain individuals are willing to experiment with various recreational substances for different reasons. The common liability to addiction (CLA) theory provides an alternative perspective related to the gateway hypothesis. Due to cannabis’s illegal standing, users may encounter situations that lead them to meet individuals who either use or sell other illegal substances.
It’s also important to note that the way you use it can have an impact on how quickly it affects you and how long the effects last. And you may not find the best way for you the first time you use it. Serotonin in the PNS plays a pivotal role in regulating respiration, a chemical reaction in our bodies that helps us produce energy.
Cannabicyclol (CBL) is a minor cannabinoid that develops when CBC degrades over time due to light exposure. The conversion of CBGA into CBCA by this enzyme was demonstrated by researchers, clarifying the biochemical pathway for CBC production by the plant. An enzyme called cannabichromenic acid synthase , CBCAS, facilitates the production of CBCA from CBGA in the plant. In a particular study, CBGA showed a reduction in kidney damage and inhibited inflammatory signaling in an animal model of nephropathy. Preclinical studies yielded especially noteworthy discoveries regarding inflammation and neurological disorders. A double-blind (placebo-controlled human laboratory study conducted in 2025 revealed that CBDA was quickly absorbed from an oral full-spectrum cannabinoid product), achieving significantly higher peak blood concentrations compared to CBD.
