Final answer:
The involvement of the Liquor and Cannabis Regulation Branch and the hospitality industry ensures enhanced safety measures by regulating the sale and consumption of these substances within the hospitality industry.
Step-by-step explanation:
The involvement of the Liquor and Cannabis Regulation Branch and the hospitality industry typically ensures enhanced safety measures. The regulation of liquor and cannabis within the hospitality industry helps to control the sale and consumption of these substances, thereby aiming to reduce negative social impacts such as crime, abuse, and sickness. In the history of the United States, initiatives like temperance movements and later prohibition were aimed at reducing the social ills associated with alcohol consumption, but these efforts often led to unintended consequences such as an increase in illegal trade and enforcement difficulties. With the changing landscape about cannabis, regulation rather than prohibition has become a more favored approach, leading not only to increased tax revenues but also to a safer and more controlled environment for consumption.
