Using cannabis while playing poker, especially over the long run, can have mixed effects. Some players may feel that it helps them relax and reduces anxiety, which could be beneficial in high-stress situations. However, cannabis can impair focus, memory, and decision-making skills, which are crucial in poker. Over time, relying on it could lead to reduced mental sharpness and poorer judgment, affecting consistent performance. While it might offer temporary relaxation, it may not be sustainable for maintaining a high level of skill and focus required for long-term success in poker.
