Cannabis, memory, and the mind: what the research explores and what Ayurveda says

Cannabis, memory, and the mind: what the research explores and what Ayurveda says

Cannabis has been part of Indian traditional medicine for thousands of years. In Ayurveda, it is called Vijaya, a name that appears in classical texts alongside guidance on how to prepare it, how much to use, and for what purpose.

Today, many Indian adults are curious about whether Vijaya-based wellness products might support their mental calm and everyday cognitive function.

This article covers both sides of that question honestly. It looks at what classical Ayurvedic texts say about Vijaya and the mind, and it summarises what published research has explored about cannabinoids and memory. Neither tradition nor research offers a simple answer, and this article will not pretend otherwise.

One thing is clear from both sources: the effects of cannabis on the mind depend heavily on the compound involved, the dose, the preparation, and the individual. That is exactly why Calmosis pairs every Vijaya product with a free consultation with a qualified physician.

If you want personalised guidance rather than general information, you should book a free consultation right now.

What Ayurveda says about Vijaya and the mind

Classical Ayurvedic texts, including the Charaka Samhita and the Sushruta Samhita, describe Vijaya as a plant with potent properties that affect both the body and the mind. Later texts such as the Sharangadhara Samhita and the Rajnighantu provide more detailed classifications.

In Ayurvedic terms, Vijaya carries tikta (bitter) and kashaya (astringent) tastes, ushna (hot) virya (potency), and laghu (light) and ruksha (dry) gunas (qualities). These properties place it primarily among herbs that can aggravate Vata and Pitta doshas when used incorrectly, but that may help pacify Kapha when used with precision.

The classical texts note that Vijaya has a particular affinity for the mind. They describe it as medhya, a term for substances that support intellect and mental function. Texts reference its use in supporting mental clarity, reducing excessive mental agitation, and promoting rest.

The same texts are careful to note that these effects depend entirely on correct preparation and appropriate dosage.

Vijaya sits in the Upavisha category, a group of semi-toxic substances that become therapeutic only when processed correctly. This is a meaningful distinction. In Ayurveda, Upavisha herbs are never used raw or in uncontrolled amounts. They require specific purification processes called shodhana, and a qualified vaidya (Ayurvedic physician) always administers them.

This traditional caution is not a warning against Vijaya. It is a framework for using it safely and effectively, which is the model that AYUSH-certified formulations follow today.

How cannabinoids interact with the brain

Cannabis contains over 100 active compounds called cannabinoids. The two most studied are THC (tetrahydrocannabinol, the compound associated with psychoactive effects) and CBD (cannabidiol, a non-intoxicating compound associated with calming effects).

The brain has a built-in system called the endocannabinoid system (ECS). The ECS is a network of receptors, primarily CB1 and CB2, spread throughout the brain and body. It plays a role in regulating mood, sleep, appetite, and memory.

The brain produces its own cannabinoid-like molecules, called endocannabinoids, to activate these receptors as needed.

THC binds directly and strongly to CB1 receptors, which concentrate in areas of the brain involved in memory formation, including the hippocampus and the prefrontal cortex. This strong binding is why high-THC cannabis can interfere with short-term memory.

THC floods receptors that are meant to receive only small, precise signals from the brain's own endocannabinoids.

CBD works differently. It does not bind directly to CB1 receptors in the same way. Instead, it appears to modulate the ECS more gently, and research has explored its potential effects on neuroprotection and anxiety reduction.

Because CBD does not produce the same receptor saturation as THC, its relationship with memory is quite different, and in some studies it appears to counteract some of THC's memory-impairing effects.

Understanding this difference matters for anyone considering a Vijaya-based wellness product. The compound profile, the ratio of THC to CBD, and the total dose all shape the cognitive effect. A physician should help you understand what is appropriate for your situation.

What research says about cannabis and memory

Research on cannabis and memory tends to focus on three cognitive domains: the learning of new information, the consolidation of that information into long-term storage, and the retrieval of stored information when needed. The findings differ significantly depending on which compound is being studied and at what dose.

A review published in Biomolecules by researchers at JSS College of Pharmacy, Mysore, examined the neurological effects of cannabis compounds with attention to cognitive function. [Editorial note: the publication year cited in the source draft as 2023 should be verified against the original paper before publish.] The review drew on a range of preclinical and clinical studies and offered a useful framework for separating THC-associated risks from CBD-associated findings.

THC and short-term memory

Research consistently associates heavy or frequent high-THC cannabis use with impairments in short-term and working memory. THC's strong action on hippocampal CB1 receptors disrupts the encoding of new information.

Studies in both animal models and human subjects show that acute THC exposure reduces the ability to form new short-term memories during the period of intoxication.

Research has also noted that THC can affect executive function, the cognitive capacity to work through a sequence of steps from a problem to a solution. This effect appears most strongly at recreational-level doses and in frequent, high-dose use patterns.

Importantly, most research on short-term memory impairment relates to recreational-level THC use or to high-dose acute exposure. The picture is less clear for low-dose, controlled, physician-supervised use, which is the context of AYUSH-regulated Vijaya formulations.

CBD and neuroprotection

The Biomolecules review from JSS College of Pharmacy, Mysore, highlights findings suggesting that CBD may support neuroprotection through several pathways, including reduction of oxidative stress and neuroinflammation.

Some studies cited in the review found that CBD may support hippocampal blood flow, which is relevant because the hippocampus is the brain's primary memory-formation structure.

These findings do not mean CBD treats or prevents memory-related conditions. The research is still developing, and most studies are preclinical or early-phase.

What the evidence does suggest is that CBD's relationship with memory differs from THC's in important ways, and that low-dose CBD-rich formulations may support cognitive wellness rather than impair it. These are possibilities the research explores, not guaranteed outcomes.

Consolidation and retrieval

Research on consolidation and retrieval is more mixed. Some studies suggest that cannabis compounds may influence the consolidation of emotionally charged memories, which has implications for stress-related conditions. This area of research is complex, the findings are not consistent across studies, and a physician should guide any application to specific conditions.

THC versus CBD: how the two main compounds differ for memory

The table below summarises how THC and CBD differ across key memory-related dimensions, based on published research findings. This is a general overview. Individual responses vary, and a physician should help you understand what applies to your situation.

Why dose and preparation matter in Ayurvedic use

The Ayurvedic classification of Vijaya as an Upavisha is not a historical footnote. It is a practical principle that shapes how responsible Vijaya products are made and used today.

In classical Ayurveda, Upavisha herbs go through shodhana, a purification process that reduces their toxic potential while preserving their therapeutic properties. For Vijaya, this traditionally involved processing the plant material with specific liquids or heat in ways that altered its chemical profile.

The goal was always to arrive at a preparation that was safe at a therapeutic dose.

Modern AYUSH-certified Vijaya formulations follow a regulated version of this principle. The AYUSH Ministry in India has established guidelines for cannabis-based Ayurvedic products that specify permissible plant parts, extraction methods, and concentration limits. These regulations exist because the dose-response relationship for Vijaya is steep. A small amount may support calm and rest.

A much larger amount can produce the cognitive disruption that research associates with high-THC recreational use.

The compound ratio within a formulation also matters. Research suggests that formulations higher in CBD and lower in THC carry a different risk profile for cognitive effects than high-THC preparations.

This is one reason why the compound balance in a Vijaya product is a question you should raise with a physician before use, not something to assume from a label alone.

This is why Calmosis does not sell Vijaya products as self-directed supplements. Every purchase comes with access to a qualified physician who can assess your constitution, your current health, and any medications you take, and then guide you to the right product and dose.

The Ayurvedic tradition and modern regulation point in the same direction: Vijaya works best under supervision.

Other Ayurvedic herbs traditionally used alongside Vijaya for cognitive support

Vijaya is not the only herb in the Ayurvedic tradition associated with cognitive wellness. Several other herbs carry a long history of use for supporting mental clarity and memory, and Ayurvedic practitioners have traditionally combined them with Vijaya in specific formulations.

Brahmi (Bacopa monnieri) is perhaps the most widely known. Classical texts describe it as a medhya rasayana, a herb traditionally used to support memory, learning, and mental endurance. Modern research has also examined Brahmi's effects on cognitive function, with several studies looking at its influence on memory consolidation.

Shankhapushpi (Convolvulus pluricaulis) is another herb classical texts classify as medhya. Ayurvedic practitioners have traditionally used it to support mental calm and cognitive clarity, and it appears in many classical formulations alongside other mind-supporting herbs.

Ashwagandha (Withania somnifera) is widely used in Ayurveda as an adaptogen, a substance traditionally used to help the body and mind respond to stress. Researchers have given attention in recent years to its potential role in supporting cognitive resilience.

These herbs appear here as context, not as a prescription. Whether any of them, alone or in combination with Vijaya, is appropriate for you depends on your individual constitution and health picture. A qualified Ayurvedic physician should assess this properly.

If you want that kind of personalised guidance, you should book a free consultation with a Calmosis physician.

Legal status of Vijaya in India and what it means for you

Many Indian adults who are curious about Vijaya-based products are also uncertain about whether they are legal. This is a reasonable question, and the answer is clear.

Cannabis as a recreational substance is regulated under the Narcotic Drugs and Psychotropic Substances (NDPS) Act, 1985. That Act restricts the production, sale, and use of cannabis resin and flowers for recreational purposes.

However, it explicitly permits the use of cannabis leaves and seeds for medical and Ayurvedic purposes, which is the basis on which Vijaya-based Ayurvedic formulations operate.

The AYUSH Ministry has issued guidelines that allow the manufacture and sale of cannabis-based Ayurvedic formulations made from permitted plant parts, produced by licensed manufacturers, and sold under Ayurvedic medicine regulations.

Several Indian states have also issued specific permissions for Vijaya cultivation and processing for Ayurvedic use, with Uttarakhand and Himachal Pradesh among the first to do so.

Calmosis products are AYUSH-certified. The company manufactures them in compliance with these regulations, from permitted plant parts, at controlled concentrations. They are not recreational cannabis products. They are traditional Ayurvedic formulations that happen to use an herb many people associate with recreational use.

If you have questions about whether a specific Calmosis product is appropriate for you given your health history or any medications you take, you should ask the free doctor consultation, not a general article. A physician can give you accurate, personalised guidance.

Does the compound ratio matter for mood as well as memory?

Research into cannabinoids and mood suggests that the balance between THC and CBD in a formulation shapes outcomes beyond memory alone. Small trials and patient reports from several studies indicate that cannabinoid formulations may support mood and a sense of calm in some adults.

These are early findings from limited trials, and they are not a basis for any specific health claim.

What the research does point to consistently is that the cognitive risks associated with cannabis, including effects on short-term memory and executive function, appear more strongly linked to THC than to CBD. Formulations that are higher in CBD and lower in THC carry a different profile in this regard.

Some researchers have noted that CBD-dominant preparations may be worth considering when cognitive effects are a concern, because CBD does not produce the same receptor saturation as THC.

It is also worth noting that several other substances, including certain Western medicines used for mood support and a number of herbal preparations, have their own documented interactions with mood and cognition. No compound exists in isolation.

A physician reviewing your full health picture, including any other supplements or medicines you take, is the right person to assess whether a Vijaya-based formulation fits your situation. You should start that conversation by booking a free consultation with a Calmosis physician.
