Understanding The Importance Of Different CBD:THC Ratios

The cannabis community is ripe with development and innovation. Breeders are now creating strains with diverse CBD:THC ratios, and scientists are urgently striving to discover their potential.

The CBD:THC ratio of your cannabis is an important factor to consider. Put simply, a CBD:THC ratio is the amount of CBD in your cannabis in relation to the amount of THC. It affects the way cannabinoids interact with your body, influencing nearly every aspect of the experience. Knowing the different common ratios and their effects can help you choose the bud that is right for you or a situation.

It wasn’t long ago that users were stuffing an unknown bud into the end of a pipe and hoping for the best. Thanks to science that is all changing.

THC And CBD: What’s The Difference?

THC And CBD: What’s The Difference?

THC and CBD are the most thoroughly studied cannabinoids found in cannabis. Most of the research has been conducted on cell and animal models, although a handful of human trials have yielded promising results. Both molecules exert some of their effects via the endocannabinoid system, a series of receptors found on different cell types throughout the body. This system comprises two main receptor types: CB1 and CB2. Depending on the ratio they are present in, they can cause different effects as they work in tandem—a phenomenon known as the entourage effect.

THC primarily targets CB1 receptors, which are located[1] mainly in the central and peripheral nervous system. By binding to these receptors, THC is able to exert its characteristic psychoactive effects. In contrast, CBD has a low affinity for both CB1 and CB2 receptors. This lack of affinity for CB1 is why CBD doesn’t produce a high. CBD also produces its effects via serotonin, vanilloid, and other receptors. Through these mechanisms of action, THC and CBD have demonstrated some intriguing qualities.

Why CBD:THC Ratios Are Important

Why CBD:THC Ratios Are Important

As touched upon, the ratio of CBD to THC in your cannabis is important as it affects the potential chemical response in your body. When it comes to the high, CBD can temper the psychoactive nature of THC. This means the more CBD in relation to THC, the more manageable the high is likely to be. At the same time, it reduces the severity of the potential side effects of THC, such as paranoia. Conversely, if the amount of CBD is low in relation to THC, the high will likely be more psychoactive. Any potential side effect associated with THC will also be stronger.

Each strain of cannabis features slightly different levels of THC and CBD, and the amount of each cannabinoid will change the overall effect of a given strain. CBD produces a non-psychoactive, clear-headed effect that helps to ease the mind and chill the nerves. In contrast, THC produces a psychoactive effect that varies greatly depending on the terpene content. The high can either be relaxing and soothing or energising and euphoric. THC can help to raise the spirits and has a pacifying effect on the body.

Popular CBD:THC Ratios

Cannabis with different ratios of CBD and THC are becoming more and more popular. Below is an explanation of some common ratios and what effect they may offer.

CBD:THC — 0:1 ("Full THC")

CBD:THC — 0:1 (

A 0:1 ratio of CBD to THC is not common. However, those strains close to it have made quite a name for themselves. Users opt for high-THC/low-CBD strains primarily for the psychoactive high. These strains often provide extreme uplifting and euphoric experiences, as well as couch locking stoned effects. For inexperienced users, it can be hard to remain functional.

Top 5 Full-THC Strains

Although these full-THC strains are extremely potent and powerful, this is exactly what some users are looking for. Here are some of the strongest strains around, which have even won awards for their potency!

Banana by Zamnesia Seeds

First up is our very own Banana. Straight from sunny California, this sativa-dominant strain will send you to tropical heaven within the first few puffs. A powerful 28% THC content—the highest on this list—combined with a peppery and lemony flavour is the perfect combo for an uplifting and mentally stimulating strain. Better enjoyed during the day, the indica side will still grant you a relaxing and soothing effect, with the bonus of stimulating your creative mind.

After a flowering time of 10 weeks, growers can expect yields of between 350 and 400g/m² indoors.

CBD:THC — 1:2

CBD:THC — 1:2

Cannabis strains that feature a 1:2 ratio are more common in today’s market. They offer a psychoactive high, but in a much more mellow, manageable and gradual form. It means the build-up of effects is slower, with a relaxed and happier mood being more noticeable, building to euphoria and couchlock if use continues.

This 1:2 ratio allows for a great deal more control over the experience—especially for novice users—but can still result in an experience that makes it hard to function if you go overboard. The reason for this difference is that increased levels of CBD may work at CB1 receptors to mediate some of THC’s psychoactive effects. It also means the side effects of THC are less likely.

It is worth noting that most recreational cannabis strains on the market fall somewhere between the 0:1 and 1:2 ratios—very few hit them on the mark. Those that hit a middle ground between the two are considered to be the classic stoner experience and are the most common on the market.

Top 5 Strains — 1:2 CBD:THC

Genetics with this ratio are perhaps the most sought-after on the market. We have selected 5 for you so you don’t have to waste your time scrolling through pages and pages of results.

The demand for them is increasing as users look to include more CBD in their experience. There are even a few seedbanks actively focusing on developing 1:1 strains.

CBD:THC — 2:1

CBD:THC — 2:1

Cannabis strains with a 2:1 CBD:THC ratio will still induce a slight buzz, but it will be extremely minimal. They are more suited to sensitive users and those who still want both cannabinoids present in their cannabis, but don’t want the more psychoactive effects of THC to be prevalent. Traditional recreational users do not often seek 2:1 strains.

The high of a 2:1 strain is truly functional, and the growing popularity of such varieties is allowing them to carve out a niche. You can even find strains with this ratio appearing in the occasional Dutch coffeeshop.
