What Is the Main Drug in Cannabis? A Guide to THC
The main drug in cannabis is THC (delta-9-tetrahydrocannabinol), the psychoactive compound that produces the 'high.' It binds to cannabinoid receptors in the brain and central nervous system, altering mood, perception, and behavior.
What Is the Main Drug in Cannabis?
THC (delta-9-tetrahydrocannabinol) is the main drug in cannabis—the chemical responsible for the plant's psychoactive effects. When you smoke, vape, or ingest cannabis, THC travels through the bloodstream to the brain, where it binds to cannabinoid receptors in the central nervous system. This interaction triggers the release of dopamine, producing the euphoria, relaxation, and altered perception commonly called a "high."
THC is just one of over 100 cannabinoids—compounds made by the Cannabis sativa plant—but it's the most abundant and potent in terms of psychoactivity. Its concentration varies widely by strain and product, which is why some cannabis feels stronger than others. For nearly 18 years, our team at Cornerstone Wellness has helped customers in Eagle Rock, Glassell Park, and across Los Angeles understand these differences and choose products that match their comfort level.
If you're new to cannabis, knowing that THC is the active drug is the first step. From there, you can explore how it works, what it does, and how to use it responsibly. Our Eagle Rock dispensary team is always available to answer questions and guide you through our selection of flower, edibles, and more.
Effects and Uses of THC
THC's effects on the body are wide-ranging. In the short term, it can produce feelings of euphoria, relaxation, heightened sensory perception, and increased appetite. It can also cause side effects like dry mouth, red eyes, impaired memory, and slower reaction times—especially at higher doses.
Medically, THC is used to help manage chronic pain, nausea (particularly from chemotherapy), muscle spasticity, and appetite loss in conditions like HIV/AIDS. Many patients in our community use THC products for these purposes, and we carry a variety of medical marijuana options—including tinctures, capsules, and edibles—that offer precise dosing for therapeutic use.
Because THC affects everyone differently, starting with a low dose and going slow is the safest approach. Our budtenders can help you find the right product and potency for your needs, whether you're seeking relief or recreation.
THC vs. CBD: What’s the Difference?
| Aspect | THC (delta-9-tetrahydrocannabinol) | CBD (cannabidiol) |
|---|---|---|
| Psychoactive | Yes—produces a "high" | No—non-intoxicating |
| Primary effects | Euphoria, relaxation, altered perception | Calm, pain relief, anti-inflammatory |
| Common uses | Recreation, pain, nausea, appetite stimulation | Anxiety, seizures, inflammation, sleep |
| Side effects | Dry mouth, red eyes, memory impairment, paranoia | Generally mild: fatigue, diarrhea, appetite changes |
| Legality | Regulated; varies by state | Legal in many places; derived from hemp is federally legal |
| Drug testing | Shows up on standard drug tests | May show up if full-spectrum; isolates usually don't |
Both are cannabinoids from the cannabis plant, but they interact differently with the body. THC binds directly to CB1 receptors in the brain; CBD influences them indirectly, which is why it doesn't get you high.
Choosing between them depends on your goals. If you want relief without intoxication, CBD might be the right choice. If you're open to the psychoactive effects, THC could be what you're looking for. Many people use both together for what's called the "entourage effect."
Is THC Addictive?
Yes, THC can be addictive for some people. Research suggests that about 9% of people who use cannabis will develop a dependence, and the risk rises to around 17% if you start in your teens. Addiction is characterized by cravings, withdrawal symptoms (irritability, insomnia, loss of appetite), and continued use despite negative consequences.
It's important to note that not everyone who uses THC becomes addicted. Frequency, dosage, genetics, and mental health all play a role. If you're concerned about your use, talk to a healthcare professional. For most adults, responsible use—like choosing lower-potency products or using occasionally—can minimize risks.
THC: Legal Status and Medical Uses
In California, THC is legal for both medical and recreational use. Adults 21+ can purchase cannabis with a valid ID, and medical patients 18+ with a valid medical card. The California Department of Cannabis Control regulates dispensaries to ensure safety and compliance. State regulations require testing for potency and contaminants, so you know what you're getting.
Medically, THC is used to treat conditions like chronic pain, nausea, and muscle spasms. If you're considering it for a health issue, consult a doctor who's knowledgeable about cannabis. At our shop, we can help you understand product options, but we always recommend professional medical advice for specific conditions.
What Is THCa and How Does It Become THC?
THCa (tetrahydrocannabinolic acid) is the raw, non-psychoactive precursor to THC found in fresh cannabis. In its natural state, THCa doesn't get you high—it's only when you apply heat (smoking, vaping, cooking) that a process called decarboxylation removes a carboxyl group, converting THCa into THC.
This is why eating raw cannabis leaves won't produce a high, but smoking or vaping will. Many products, like tinctures and edibles, are already decarboxylated, meaning the THC is active and ready to use. Understanding this conversion helps you choose the right product for your desired effect.
Frequently asked questions
What medicines are made from cannabis?
Several FDA-approved medications are derived from cannabis or synthetic THC. These include dronabinol (Marinol) for nausea and appetite loss, nabilone (Cesamet) for chemotherapy-induced nausea, and epidiolex, a CBD-based drug for certain seizure disorders. Other cannabis-based medicines are in development.
What are some cannabis drugs?
Common cannabis drugs include THC-dominant products like flower, edibles, and tinctures, as well as CBD-dominant products like oils and topicals. Synthetic THC drugs like dronabinol are also available by prescription. In California, you can find a wide range of these products at licensed dispensaries.
Did Jesus use cannabis in the Bible?
There is no definitive evidence that Jesus used cannabis. Some scholars speculate that certain biblical plants, like 'kaneh bosem' in Exodus, might refer to cannabis, but this is debated. The Bible does mention anointing oils and herbs, but their exact composition is unknown.
What is the addictive drug in cannabis?
THC (delta-9-tetrahydrocannabinol) is the addictive component in cannabis. It stimulates the brain's reward system, potentially leading to dependence in some users. The risk of addiction is lower than with many other substances, but it's still possible, especially with heavy use.
What are the top 3 worst addictions?
According to some addiction experts, the top three hardest addictions to overcome are heroin, alcohol, and methamphetamine. These substances have severe withdrawal symptoms and high relapse rates. Cannabis addiction, while possible, is generally considered less severe.
