The manner in which your brain cells communicate with one another is influenced by both. In the U.S. (locating CBD is simpler than finding THC; however), varying laws and restrictions regarding CBD sales exist in each state. Three prevalent varieties of THC are available: flowers or herbs, hash/hashish, and hash oil.
This weed strain is 90% sativa and contains about 18%-26% THC. Users have reported that Blue Dream provides an uplifting and energizing effect — aiding in the management of conditions like depression, anxiety, chronic pain, and PTSD. Many cannabis consumers appreciate its blend of sweet and peppery flavors. Although sativa strains of cannabis are frequently noted for their energizing properties, not every sativa strain produces this effect. Known for its slender leaves and tall stature, sativa is a distinct type of cannabis strain. The sensation of euphoria or “high” when consuming cannabis is attributable to THC.
Altered perception of time along with impaired thinking, memory, and bodily movements can result from cannabis use. Serious negative health consequences can arise from synthetic cannabinoids, which are man-made substances mimicking the compounds found cali weed in the cannabis plant. Known as Spice or K2, these products may contain significantly higher levels of THC and be considerably more potent. From 1995 to 2022, the potency of delta-9 THC in cannabis products confiscated by law enforcement increased fourfold, rising from 3.96% to 16.14%. Cannabis is commonly consumed by smoking dried plant material (referred to as “buds” or “herb,” in various forms such as joints like cigarettes), blunts (cigars or wrappers partially or fully filled with cannabis), or through pipes or bongs. Unless stated otherwise, this webpage contains information exclusively about cannabis products that contain intoxicating levels of delta-9 THC.

Medical cannabis products are included unless they have been prescribed specifically for you. Your letter should encompass your personal information (including your name and address), along with the prescribing doctor’s name and contact information. As CBD can influence liver function, regular monitoring by doctors is necessary. Should you experience any side effects from medical cannabis — it is crucial to inform your healthcare team.
Possible side effects may consist of drowsiness (dizziness), changes in appetite, digestive issues, and effects on the processing of other medications. Additionally, she has over seven years of experience in creating and editing high-quality drug information and educational materials for healthcare professionals and patients. Her expertise spans pediatrics, alternative medicine, drug information, and the creation of clinical content. The impact of alcohol consumption on cannabis remains uncertain.
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
CBD engages with the endocannabinoid system in a more indirect manner and also influences other receptor systems within the body. This explains why raw marijuana typically does not yield the same intoxicating effects as when it is smoked, vaped, or cooked. Over time — as cannabis ages, this process can occur gradually, although heat significantly accelerates it. The high experienced from THC results from its activation of CB1 receptors in parts of the brain associated with pleasure, memory, movement, sensory processing, and time perception. Marijuana can produce distinct physical and mental effects because THC also binds to these receptors.
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.
Because cannabis is an illegal drug in many countries (people may be reluctant to take part in research), and if they do agree to take part, they may not be honest about how much cannabis they actually smoke. Another difficulty researchers have is in recruiting people who smoke cannabis into studies. Research on cannabis is challenging since the plant is illegal in most countries. It states that some individuals are (for various reasons), willing to try multiple recreational substances. A related alternative to the gateway hypothesis is the common liability to addiction (CLA) theory. Because of the illegal status of cannabis, its consumers are likely to find themselves in situations allowing them to acquaint with individuals using or selling other illegal drugs.
Synthetic Cannabinoids Are Completely Different.
It is crucial to understand that the method of consumption can influence the speed of effects and their duration. The optimal method for you may not be discovered during your initial use. In the peripheral nervous system — serotonin plays a crucial role in regulating respiration, a chemical process in the body that aids in energy production.
CBL (or cannabicyclol), is a minor cannabinoid that forms when CBC is exposed to light and degrades over time. Researchers demonstrated that this enzyme converts CBGA into CBCA, establishing the biochemical pathway through which the plant produces CBC. The plant produces CBCA from CBGA using an enzyme known as cannabichromenic acid synthase, or CBCAS. In one study, CBGA reduced kidney injury and suppressed inflammatory signaling in an animal model of nephropathy. Preclinical research has produced particularly interesting findings involving inflammation and neurological conditions. In a 2025 double-blind (placebo-controlled human laboratory study), researchers found that CBDA was readily absorbed from an oral full-spectrum cannabinoid product and reached substantially higher peak blood concentrations than CBD.
