The debate in Canada centers around the current 10 mg THC limit per package of cannabis edibles. Public health professionals resist industry calls to increase this limit, while the Cannabis Council of Canada suggests a 100 mg limit, aligning with California's laws. Research indicates that infrequent consumers feel effects at low doses, raising concerns about overconsumption and child safety. However, higher limits could reduce prices, encouraging legal market transition and offering harm reduction through child-proof packaging and public education. The author leans towards increasing the limit to 100 mg, with the possibility of future increases after evaluation.

Five years after Canada legalized recreational cannabis, the policy's success is under review. The legal market faces challenges such as overproduction, environmental concerns, and lack of representation for marginalized communities. Comparisons with California's approach and Quebec's centralized model offer insights. The series aims to chart a path toward a sustainable and equitable cannabis market that prioritizes health and safety.

Five years after Canada legalized non-medical cannabis, both Canada and California face challenges despite different regulatory approaches. Canada's federal legislation provides stability, but high taxes and strict regulations hinder market access and profitability. California's industry struggles with federal prohibition, high taxes, and local resistance, sustaining an illicit market. Both regions need to prioritize social equity, recalibrate tax structures, and consider non-profit models to create a viable and just cannabis industry. Removing cannabis from the U.S. list of prohibited drugs is crucial for market success.

Canada and California, both pioneers in cannabis legalization, face similar challenges despite different regulatory approaches. Canada's federal legislation provides stability, but high taxes and strict regulations hinder market growth. California's industry struggles with federal prohibition, high taxes, and local resistance, sustaining an illicit market. Both regions need to prioritize social equity, recalibrate tax structures, and consider non-profit models to address production and retail challenges. Removing cannabis from the U.S. list of prohibited drugs is crucial for market success.

The article discusses how traditional models of understanding the brain, based on signal processing and information theory, are being replaced by insights from machine learning. It argues that the brain's complex functions are better explained through evolutionary principles and machine learning algorithms, which, like evolution, improve through small, incremental steps. The article highlights the limitations of previous models and suggests that machine learning offers a more accurate framework for understanding neural processes.

Artificial intelligence (AI) offers a mathematical approach to understanding brain computations, challenging the traditional verbal explanations of human behavior. While human explanations for actions are often unreliable, AI algorithms provide transparent, data-driven insights. The article argues that AI should not be seen as a 'black box' but as a tool for uncovering the unconscious processes that govern both machine and human decision-making. It emphasizes the need for precise, algorithmic descriptions over simplistic language-level explanations to truly understand and improve AI and human cognition.

The article discusses how traditional metaphors and models in neuroscience, which are based on signal processing and information theory, are insufficient for understanding the brain's complexities. It argues that machine learning, which mirrors the evolutionary process of natural selection, offers a more accurate framework for studying brain functions. The piece highlights the limitations of previous models and suggests that the principles of machine learning, which involve iterative improvement and flexibility, align more closely with how the brain operates. This new approach could lead to better explanations and models of neural behavior.

Daniel Bear criticizes Canadian Prime Minister Justin Trudeau for not decriminalizing cannabis in the interim period before its planned legalization on July 1, 2018. Bear argues that continuing to arrest individuals for cannabis possession is harmful and inconsistent with the goals of legalization. He suggests that a temporary decriminalization would protect users without significantly benefiting the black market, which already exists under prohibition. Bear references Trudeau's admission that cannabis is not being regulated appropriately and the disproportionate enforcement against people of color, urging for immediate action to prevent further injustices.

The article examines whether the legalization of cannabis in Canada will effectively dismantle its black market. It highlights the balanced proposals from the Task Force on Cannabis Legalization and Regulation, emphasizing the importance of taxation, pricing, and accessibility in reducing illicit sales. The text also discusses potential challenges, such as provincial regulations and corporate dominance, while expressing optimism about the thoughtful approach to cannabis reform.

The study explores an alternative olfactory subsystem in mammals, the 'necklace' subsystem, which does not rely on the conventional G-protein-coupled receptor (GPCR) chemotransduction pathway. Instead, it utilizes a previously unidentified class of chemoreceptors encoded by the Ms4a gene family. These receptors detect specific odors, including ethologically relevant odorants like fatty acids and the putative mouse pheromone 2,5-DMP. The findings suggest that each necklace sensory neuron expresses multiple members of the Ms4a gene family, which could indicate a distinct perceptual role for the necklace subsystem in mammalian olfaction.

The article criticizes the Conservative Party's drug policies, particularly those advocated by Stephen Harper, as outdated and not supported by scientific evidence. It argues for the decriminalization of cannabis and the implementation of public health approaches to drug abuse, citing successful examples from Colorado and Portugal. The author emphasizes the need for safe injection facilities and criticizes Harper's plan to increase funding for targeting drug labs as ineffective. The article calls for a more logical and positive approach to drug policy.
