Prelims level: Cannabis , THCBD, NDPS Act, Exception for 'Bhang'
Mains level: Therapeutic uses of narcotic substances
In the news
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.

What are Representative Concentration Pathways (RCPs)?
The Representative Concentration Pathways (RCPs) were rolled out as part of the Fifth Assessment Report (AR5) of the IPCCin 2014.
These are basically emission scenarios that depict pathways of greenhouse gas and aerosol emissions resulting from human activities over time, crucial for climate modelling and forecasting.
These pathways were introduced to provide a consistent set of GHGs concentration trajectories for climate modelling and research purposes.
The RCPs were officially selected and defined based on their total radiative forcing levels in the year2100.
These pathways describe various climate change scenarios based on the amount of greenhouse gases emitted.
RCP 2.6: Limits global warming to less than 2°C above pre-industrial levels while also attempting to keep ocean acidification under control. Greenhouse gas emissions must be reduced significantly compared to current levels.
RCP 4.5: Reflects an intermediate scenario where emissions peak around 2040 and then gradually decrease. Global mean temperature rise is projected to reach approximately 2°C above pre-industrial levels by 2100.
RCP 6: Stabilizes radiative forcing at 6 watts per square meter (W/m²) after 2100 following peaking around mid-century. It aims to achieve a lower level of global warming but does not exclude temporary overshoots beyond 2°C.
RCP 8.5: Presents a high-emission scenario characterized by increasing radiative forcing throughout the century. By 2100, it results in a global mean temperature increase of over 4°C above pre-industrial levels.

In quantum mechanics, particles exhibit wavelike properties, and their behavior is governed by the Schrodinger equation, which describes how these waves behave.
Key Concepts:
Wave-Particle Duality: Quantum objects, like electrons and photons, exhibit both particle-like and wave-like properties simultaneously, known as wave-particle duality.
Superposition: Objects in quantum science can exist in superposition states, where their quantum state is a combination of multiple states until measured. This concept allows qubits to represent multiple states simultaneously.
Quantum States and Qubits: Qubits are the fundamental units of quantum information, representing a two-state quantum system that can be in a superposition of 0 and 1 until measured.
Quantum Gates: Quantum computers use quantum gates to manipulate qubits through reversible unitary transformations, enabling complex computations based on algorithms.
Entanglement: Quantum entanglement is a unique property where multiple qubits can be correlated in such a way that the state of one qubit is dependent on the state of another, allowing for powerful computational capabilities.
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.
Just as the sporting world anticipates the Olympics every four years, the cryptocurrency community eagerly awaits its own quadrennial event: the Bitcoin halving.

Bitcoin
Bitcoin is a digital currency created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto.
It operates on a decentralized distributed ledger called blockchain, which records all transactions.
The blockchain acts as a public ledger where each new set of verified transactions (a “block”) is added to the existing chain, creating an unalterable history of all Bitcoin transactions.
The process of verifying these blocks, referred to as mining, requires solving complex mathematical problems, which not only secures the network but also rewards miners with newly minted Bitcoins.
What is Bitcoin Halving?
Reward Reduction: Bitcoin halving entails a 50% reduction in the reward paid to Bitcoin miners for successfully processing cryptocurrency transactions. This reduction aims to maintain the scarcity of Bitcoin and regulate its supply.
Mining Process: Bitcoin miners utilize advanced computer equipment to solve complex mathematical puzzles through a process called ‘Proof of Work,’ crucial for expanding Bitcoin’s blockchain.
Blockchain Integrity: The halving mechanism ensures the integrity and security of the Bitcoin blockchain by adjusting the rate at which new coins are created, maintaining a controlled inflation rate.
Analogical Explanation
Grocery Store Contest: Analogous to a group of cashiers competing to tally up items in a grocery store, Bitcoin miners race to solve cryptographic puzzles to claim rewards.
Equipment Advantage: Cashiers with superior equipment have a higher chance of winning the contest, akin to Bitcoin miners with cutting-edge technology.
Economic Incentives: The analogy highlights the economic incentives driving both miners and cashiers to optimize their resources for maximum efficiency and profitability.
Implications for Crypto Investors
Scarcity and Value: Bitcoin halving reduces the rate at which new coins are released, enhancing Bitcoin’s scarcity and potentially driving up its value, similar to gold.

Project Evolution:
The foundation stone of the Shahpur Kandi Barrage Project was laid by then Prime Minister PV Narasimha Rao in 1995.
In 2016, the government started to optimize water resources from the Sutlej, Beas, and Ravi rivers for Indian farmers, leading to renewed efforts to complete the project.
Finally, Jammu and Kashmir and Punjab signed an agreement in 2018 to resume work on the Shahpur-Kandi dam project, which had been hanging fire for the last 40 years.
Project Capacity:
The project comprises a 5 m high concrete gravity dam, a 7.7 km long hydel channel, two head regulators, and two powerhouses.
It is expected to generate up to 206MW of electricity and provide irrigation to Punjab (5,000 Ha) and Jammu and Kashmir (32,173 Ha).
Indus Waters Treaty
The Indus Waters Treaty is an agreement between India and Pakistan, mediated by the World Bank in 1960.
The treaty allocates the Western Rivers (Indus, Jhelum, Chenab) to Pakistan and the Eastern Rivers (Ravi, Beas, Sutlej) to India.
However, the treaty permits limited usage of the Eastern Rivers by Pakistan and vice versa.
The treaty created the Permanent Indus Commission, comprising one representative from each nation, to facilitate communication and dispute resolution.
The treaty facilitated the construction of dams, link canals, barrages, and tube wells, providing water to Pakistan as per its previous entitlement.
The treaty came into effect due to the partition in 1947, leading to the division of the water systems.
After the expiry of the temporary Standstill Agreement of 1947, India started holding back water from canals flowing towards Pakistan.
The Inter-Dominion Accord of May 4, 1948, mandated India to supply water to Pakistani areas of the basin in exchange for yearly payments.
