Cannabis (Cannabis sativa) has long intrigued psychiatrists due to its impact on mood and cognition, prompting research into its potential therapeutic applications for conditions like schizophrenia and mood disorders.
Do you know?
The Narcotic Drugs and Psychotropic Substances Act, 1985 regulates cannabis by defining it under Section 2(iii) of the act.
Cannabis, also known as hemp, includes various forms such as charas (resin), ganja (flowering or fruiting tops), and any mixture or drink prepared from these forms.
However, interestingly, bhang, a preparation of cannabis, is NOT covered under this act and remains beyond its purview.
Bhang is permitted for production and sale by many States as it falls outside the definition of cannabis under the NDPS Act.
What is Cannabis?
Cannabis, also known as marijuana, weed, pot, or ganja, is a genus of flowering plants that belongs to the Cannabaceae family.
It is primarily known for its psychoactive properties due to the presence of compounds such as tetrahydrocannabinol (THC).
This THC interacts with the brain’s cannabinoid receptors, resulting in various effects including relaxation, euphoria, altered perception of time, and increased appetite.
The plant contains over 100 different cannabinoids, with THC and cannabidiol (CBD) being the most well-known and studied.
Why discuss this?
Researchers at the University of British Columbia initiated a clinical trial to explore the efficacy of cannabidiol (CBD) in treating bipolar depression, offering promise for addressing depressive episodes in bipolar disorder.
While delta-9-tetrahydrocannabinol (THC) is the primary psychoactive compound in cannabis, CBD has garnered attention for its potential antipsychotic and neuroprotective effects.
Understanding the Cannabinoid System
Receptor Mechanisms: The human cannabinoid system, comprising CB1 and CB2 receptors, plays a crucial role in modulating various bodily functions, including pain, memory, and appetite, with THC exerting acute effects on motor control and memory.
Endo-cannabinoid System (ECS): The ECS, governed by endogenous molecules, regulates neurotransmitter activity, influencing mood and cognitive processes.
Therapeutic Applications
Medical Uses: THC and synthetic cannabinoids are utilized to stimulate appetite, alleviate nausea, and manage pain associated with conditions like HIV-AIDS and cancer.
Addiction and Withdrawal: Debate surrounds the addictive potential of THC, with animal studies suggesting addictive responses and withdrawal symptoms upon cessation of heavy use.
Psychiatric Implications
Mood Effects: Cannabis’ impact on mood is multifaceted, with reports suggesting associations with depression and bipolar disorder, although rigorous scientific scrutiny is lacking.
Psychotic Risks: Individuals with psychotic illnesses, including schizophrenia, exhibit heightened susceptibility to cannabis-induced psychotic symptoms, with youth cannabis use potentially advancing the onset of schizophrenia in genetically vulnerable individuals.
Policy Considerations
Global Trends: The global trend toward legalizing medical and recreational cannabis underscores the need for informed policymaking to mitigate risks, particularly for vulnerable populations such as children and individuals with mental illnesses.
Decriminalization Debate: Broader debates on decriminalization necessitate measures to prevent commercialization and ensure safeguards against misuse, emphasizing protection for vulnerable segments of society.
Conclusion
Navigating the complexities of cannabis necessitates a balanced approach, leveraging its therapeutic potential while addressing associated risks through evidence-based policymaking and clinical interventions.

Understanding Qubits and their Fragility
Classical vs. Quantum: Similar to classical computers, which rely on bits with two states (0 and 1), quantum computers operate using qubits—physical systems with two quantum states.
Unique Feature: Unlike classical bits, qubits can exist not only in one of the two states but also in a superposed state, where they simultaneously hold both states. However, this superposition is fragile and prone to disruption from external interactions.
Challenges in Qubit Implementation
Requirement for Identical Qubits: A collection of qubits is necessary for a quantum device, each needing to be identical—a challenge due to manufacturing imperfections.
Controllability and Robustness: Qubits must be controllable, allowing manipulation and interaction, while also being robust enough to maintain quantum features at room temperature over extended durations.
Exploring Qubit Systems
Diverse Options: Various physical systems serve as qubits, including superconducting junctions, trapped ions, and quantum dots. However, these systems typically require low temperatures or vacuum conditions for operation.
High Cost Barrier: The necessity for such conditions renders quantum computers based on these technologies expensive, prompting research into simpler, cost-effective alternatives.
Breakthrough in Room-Temperature Qubits
Metal-Organic Framework (MOF): In a recent collaborative study reported in Science Advances, researchers in Japan achieved qubits at room temperature within a metal-organic framework.
Composition: The MOF consists of repeated molecular arrangements, with zirconium as the metal component and an organic molecule containing the chromophore pentacene bridging the metal atoms.
Singlet Fission Mechanism: Singlet fission, facilitated by interaction between chromophores within the porous MOF networks, generates two triplet excited chromophores from a singlet excited state.
Enhanced Stability: The rotation of chromophores within the MOF networks modulates interactions, ensuring long-lived coherence of triplet states even at room temperature.
