After-hours marijuana use does not decrease productivity
One study shows that the quality of work does not suffer from regular evening cannabis use.

According to a recent research, marijuana doesn't make people as lazy or unreliable, and it examined how cannabis doesn't affect people's performance or productivity the next day after work. The paper, published in SAGE JOURNALS, is titled, "Changed Conditions or Much to Do Against Nothing? A Study of Timing of Cannabis Use Relative to Impact on Performance". The research looked at how marijuana at different times of the day affected how people were able to get jobs done and meet their job demands. The research also examined their behavior towards colleagues and their attitudes towards their work. According to the results, marijuana use after work did not affect measurements of workplace performance, but the same could not be said for use before or during work. The drug affected their ability to complete tasks, impaired concentration, and reduced their ability to solve problems while at work. The study hadn't provided many details on how much cannabis participants used - just that they used it before, during, or after work. The paper concluded: "Cannabis use among the general public has exploded in the last decade, yet there has been virtually no empirical research into the performance-related effects of cannabis use in organizational science for more than two decades. This is clearly problematic As our knowledge and understanding of the workplace has increased concurrently with the evolution of the types and use of cannabis, this study made a first attempt to fill this gap by examining the relationship between different forms of cannabis use and different forms of performance in the workplace Findings correlating certain types of cannabis use (ie, before work) and performance in the workplace are important for organizations with a substance use policy, but also zero findings between cannabis use after work are important and workplace performance. Ultimately, organizations and government agencies must provide evidence of their beliefs and substance policies. We hope that this research will serve as the basis for a potentially rich and long field of investigation in the years to come ".
