thc v cbd

Some evidence suggests that the combined effects of CBD and THC may be dependent on dose. A 2019 study, for example, found that low doses of CBD actually played a role in amplifying the psychoactive effects of THC, while high doses of CBD reduced THC’s effects.

CBD that comes from marijuana may contain more THC, which may not be ideal for people who are trying to avoid THC. Some CBD products that are produced from cannabis, for example, may contain more THC than the label suggests.

Before choosing a THC or CBD product, it is important to check your state laws to ensure that these products are legal where you live. Federal law mandates that hemp-derived CBD products should contain less than 0.3% THC, but even those trace amounts are still illegal in some states.

Sourced from marijuana

This interest is likely to continue to grow as cannabis and marijuana products become legal in more states. A number of different products have emerged that contain CBD, THC, or both that are designed to alleviate ailments such as stress, anxiety, and insomnia. In order to understand the side effects and potential benefits of these products, it is important to first understand the differences between CBD and THC.

Neurotransmitters are chemical messengers that relay signals between nerve cells in the body. They play an important role in a wide range of functions including sleep, pain, appetite, mood, and the immune system.

What Is CBD?

THC and CBD have an effect on the endocannabinoid system, a system that plays an important role in maintaining homeostasis. Researchers are still working to understand the ins and outs of this complex system, but they do know that it is associated with processes including memory, appetite, sleep, mood, and fertility.

While CBD can come from either hemp or marijuana, it is often derived from hemp in order to avoid the addition of larger amounts of THC. THC, on the other hand, is derived from marijuana.

Of 4 RCTs, 1 found THC-CBD superior to THC but this was inconsistent within the study and with other studies. Adverse events are prevalent with THC, CBD, and THC-CBD. While some early poor-quality research in healthy users suggests CBD attenuates some psychiatric effects of THC, better research in real patients is needed to verify any benefits of specific components.

Evidence

An RCT in 177 patients with refractory cancer pain taking strong opioids (about 270 mg of morphine) compared THC-CBD, THC, and placebo for 2 weeks. 2

Context

Four RCTs compared THC, CBD, or both combined.

Balanced CBD/THC strains will be a little more euphoric than CBD-dominant strains, though they’re much less likely to induce anxiety, paranoia, and other negative side effects. Strains like these tend to be the most effective for pain relief, and they’re also well-suited for THC-sensitive consumers who’d like a mellow buzz.

One of the earliest success stories involves a young girl named Charlotte who was given an ingestible oil derived from Charlotte’s Web , a CBD strain that was specifically developed to provide her with all the benefits of the drug without the high.

Dravet’s Syndrome is notoriously resistant to current treatment methods. People with the condition are plagued by seizures, often up to hundreds a day, and they usually worsen as people age and can be life-threatening. Currently, treatment methods include having a child wear an eyepatch, specialized diets, and brain surgery, but all have mixed success rates.

High-CBD strains tend to deliver very clear-headed, functional effects without the euphoric high associated with high-THC strains. They’re typically preferred by consumers who are extremely sensitive to the side effects of THC (e.g., anxiety, paranoia, dizziness).

What are the medicinal effects of CBD?

Keep in mind that CBD levels may vary from crop to crop—even from plant to plant. We also recommend checking with dispensaries about the specifics of their strains’ CBD levels. It’s always a good idea to purchase only lab-tested products that clearly state the CBD/THC levels so you know what kind of experience to expect.

This does not mean that CBD, by itself, cannot offer an effect. High doses of CBD often produce a profoundly relaxing experience. Like stepping out of a hot tub, your body may feel tingly and relaxed, and your brain may be clear.

A high-CBD strain would also be a great choice for someone needing to medicate throughout the day to control pain, inflammation, anxiety, or other chronic conditions.

CBD vs. THC: legality

An easy way to think about it is that THC is defined by what cannabis makes you feel, while the effects of CBD can’t be felt. The important distinction is that, unlike THC, CBD will not intoxicate you. It also addresses one of the most common reasons people choose to use CBD—pain management.

CBD strains can be consumed just as you would THC strains. You can smoke or vaporize CBD-rich flower, eat a CBD-infused edible, swallow a CBD oil capsule, apply a CBD lotion, or use a CBD tincture sublingually. Hemp products also contain CBD, though it is a less efficient source and lacks the beneficial chemical diversity of cannabis-derived CBD products (more on that here).
