Basic Cannabis Questions

1. What exactly is cannabis?

Cannabis is a genus of flowering plants in the Cannabaceae family, primarily consisting of three species: Cannabis sativa, Cannabis indica, and Cannabis ruderalis. The plant contains over 100 chemical compounds called cannabinoids, with THC (tetrahydrocannabinol) and CBD (cannabidiol) being the most well-known. Cannabis has been used for medicinal, recreational, and industrial purposes for thousands of years.

2. What’s the difference between hemp and marijuana?

The distinction is primarily legal and based on THC content. Hemp is cannabis containing 0.3% THC or less by dry weight, making it non-intoxicating. It’s primarily grown for industrial uses like textiles, food products, and CBD extraction. Marijuana refers to cannabis with higher THC levels that produce psychoactive effects. Both are the same plant species but bred for different purposes.

3. How does cannabis affect the brain?

Cannabis interacts with the body’s endocannabinoid system, a network of receptors throughout the brain and body that help regulate various functions. THC binds to CB1 receptors in the brain, particularly in areas controlling memory, coordination, pleasure, and time perception, creating the characteristic “high.” CBD doesn’t directly bind to these receptors but influences them indirectly, often producing calming effects without intoxication.

4. Is cannabis addictive?

Cannabis can be habit-forming for some people, with about 9% of users developing cannabis use disorder. This rate increases to about 17% for those who start using in adolescence. While physical dependence is less severe than with substances like alcohol or opioids, psychological dependence can occur, especially with heavy, regular use. Withdrawal symptoms are typically mild and may include irritability, sleep difficulties, and decreased appetite.

5. How long does cannabis stay in your system?

Detection times vary significantly based on usage frequency, body composition, and testing method. In urine, cannabis can be detected for 3-30 days after use, with occasional users typically testing clean within a week and daily users potentially testing positive for a month or more. Blood tests detect recent use (2-12 hours), while hair tests can show use up to 90 days prior. Saliva tests typically detect use within 24-72 hours.

Medical Cannabis Questions

6. What conditions can medical cannabis treat?

Medical cannabis has shown efficacy for numerous conditions, including chronic pain, epilepsy, nausea from chemotherapy, muscle spasticity in multiple sclerosis, and certain mental health conditions like PTSD and anxiety. It’s also used for glaucoma, inflammatory bowel disease, and as an appetite stimulant. However, the level of scientific evidence varies by condition, and patients should consult healthcare providers for personalized advice.

7. What’s the difference between THC and CBD?

THC is the primary psychoactive compound that creates the “high” associated with cannabis. It can also provide pain relief, reduce nausea, and stimulate appetite. CBD is non-intoxicating and may help with anxiety, inflammation, seizures, and sleep issues. Many medical users prefer CBD-dominant products for therapeutic benefits without impairment, while others benefit from the combined effects of both compounds.

8. Can you overdose on cannabis?

Fatal overdoses from cannabis alone are extremely rare, if they occur at all. However, consuming too much can lead to uncomfortable effects like anxiety, paranoia, rapid heartbeat, and nausea—particularly with edibles, which have delayed onset and longer duration. The key is starting with low doses and waiting adequate time before consuming more.

Consumption Methods

9. What are the different ways to consume cannabis?

Common methods include smoking (joints, pipes, bongs), vaporizing, edibles (gummies, chocolates, beverages), tinctures, topicals (creams, balms), and concentrates (wax, shatter, rosin). Each method has different onset times, duration, and bioavailability. Smoking and vaping provide rapid effects lasting 1-3 hours, while edibles take 30-120 minutes to work but last 4-8 hours.

10. Why do edibles affect people so differently?

Edibles are processed through the digestive system and liver, where THC is converted to 11-hydroxy-THC, a more potent compound. Individual factors like metabolism, body weight, tolerance, stomach contents, and liver function all influence how edibles are processed. This explains why the same dose can have vastly different effects on different people, or even the same person on different occasions.

11. Is vaping healthier than smoking?

Vaporizing heats cannabis to a temperature that releases cannabinoids and terpenes without combustion, eliminating many harmful byproducts associated with smoking. Studies suggest vaping produces fewer respiratory irritants and toxic compounds than smoking, making it a potentially healthier consumption method. However, long-term research on vaping is still limited.

Legal and Regulatory Questions

12. Where is cannabis legal?

Cannabis laws vary globally and are rapidly evolving. Many U.S. states have legalized medical and/or recreational cannabis, while others maintain prohibition. Several countries including Canada, Uruguay, and parts of Europe have implemented various forms of legalization. Always check current local and state laws, as they can be complex and frequently changing.

13. Can you travel with cannabis?

Traveling with cannabis is complicated due to varying laws. Even in legal states, crossing state lines with cannabis remains federally illegal in the U.S. International travel with cannabis is generally prohibited and can result in serious legal consequences. Some legal states allow transporting cannabis within their borders, but regulations vary significantly.

14. How is cannabis tested for potency and safety?

Legal cannabis markets typically require laboratory testing for potency (cannabinoid levels), pesticides, heavy metals, residual solvents, and microbials like mold and bacteria. Testing protocols vary by jurisdiction but generally aim to ensure consumer safety and accurate labeling. This testing helps consumers make informed decisions and ensures products meet safety standards.

Cultivation Questions

15. How is cannabis grown?

Cannabis can be grown indoors or outdoors, with each method having advantages. Indoor cultivation allows for controlled environments, year-round growing, and higher potency, but requires significant energy and equipment. Outdoor growing is more sustainable and cost-effective but depends on climate and growing seasons. The plant requires specific light cycles, nutrients, and environmental conditions to thrive.

16. What are cannabis terpenes?

Terpenes are aromatic compounds found in many plants, including cannabis. They contribute to the plant’s distinctive smell and may influence its effects through the “entourage effect”—the theory that cannabis compounds work better together than in isolation. Common terpenes include myrcene (sedating), limonene (mood-elevating), and pinene (alertness-promoting).

17. Why are there so many cannabis strains?

Cannabis has been selectively bred for thousands of years, creating countless varieties with different cannabinoid profiles, terpene combinations, and effects. Modern breeding focuses on specific traits like potency, flavor, yield, or medicinal properties. Popular strains like Blue Dream, OG Kush, and Sour Diesel represent distinct genetic lineages with characteristic effects and flavors.

Obscure and Advanced Questions

18. What is the endocannabinoid system?

The endocannabinoid system (ECS) is a complex biological system discovered in the 1990s that helps maintain homeostasis in the body. It consists of endocannabinoids (naturally produced compounds), receptors (primarily CB1 and CB2), and enzymes that break down endocannabinoids. The ECS regulates functions like sleep, appetite, pain, immune response, and mood, explaining why cannabis can affect so many different bodily functions.

19. Can pets use cannabis products?

While some pet owners use CBD products for their animals, veterinary research is limited. CBD may help pets with anxiety, pain, and seizures, but THC is toxic to dogs and cats. Pet-specific CBD products with no THC are available, but pet owners should consult veterinarians before use. Dosing for animals differs significantly from humans, and safety data remains incomplete.

20. What is cannabis hyperemesis syndrome?

Cannabis hyperemesis syndrome (CHS) is a rare condition affecting some heavy, long-term cannabis users, characterized by severe nausea, vomiting, and abdominal pain. Paradoxically, while cannabis typically helps nausea, CHS causes the opposite effect. Hot showers or baths often provide temporary relief. The only known cure is complete cessation of cannabis use, which typically resolves symptoms within days to weeks.

21. How does cannabis affect dreaming?

Cannabis, particularly THC, suppresses REM sleep—the stage when most vivid dreaming occurs. Regular users often report fewer dreams, while those who stop using frequently experience a “REM rebound” with intense, vivid dreams for several weeks. This phenomenon is part of why some people have unusual dreams when they take tolerance breaks or quit cannabis.

22. What is decarboxylation and why does it matter?

Raw cannabis contains THCA and CBDA—acidic precursors to THC and CBD. Decarboxylation is the process of applying heat to convert these inactive compounds into their active forms. This occurs naturally when smoking or vaping, but must be done intentionally when making edibles. Without proper decarboxylation, homemade edibles will have minimal psychoactive effects.

23. Can you become tolerant to cannabis?

Yes, regular cannabis use can lead to tolerance, requiring higher doses to achieve the same effects. Tolerance develops as cannabinoid receptors become less sensitive to THC. Taking periodic “tolerance breaks” (T-breaks) can help reset sensitivity. The length needed varies but typically ranges from a few days to several weeks. Some users rotate strains or consumption methods to combat tolerance.

24. What are minor cannabinoids and why are they important?

Beyond THC and CBD, cannabis contains dozens of minor cannabinoids like CBG (cannabigerol), CBN (cannabinol), and Delta-8 THC. These compounds may have unique therapeutic properties and can modify the overall effects of cannabis products. CBG may help with inflammation and bacterial infections, while CBN is associated with sedation. Research into minor cannabinoids is expanding rapidly.

25. How is synthetic cannabis different from natural cannabis?

Synthetic cannabinoids (often called “Spice” or “K2”) are artificial chemicals that bind to cannabinoid receptors but have unpredictable and potentially dangerous effects. Unlike natural cannabis, synthetic versions can cause severe health problems including seizures, kidney damage, and psychotic episodes. These products are often sprayed on plant material and sold as “legal” alternatives, but they’re far more dangerous than natural cannabis.

Conclusion

Cannabis remains one of the most studied yet misunderstood plants on Earth. As research continues and laws evolve, our understanding of its therapeutic potential, risks, and proper use continues to grow. Whether you’re considering cannabis for medical purposes, curious about its effects, or simply want to understand this culturally significant plant better, staying informed about current science and regulations is essential.

Remember that cannabis affects everyone differently, and what works for one person may not work for another. If considering cannabis for medical purposes, consult with healthcare professionals familiar with cannabis medicine. Always consume responsibly, start with low doses, and be aware of your local laws and regulations.
