I can provide some general information on marijuana smoking.
Smoking 15-20 cones (joints) of marijuana nearly every day is a significant amount of cannabis consumption. The average marijuana smoker varies depending on location and age group, but most marijuana users do not consume this amount on a daily basis.
Regular and heavy marijuana use can have potential negative effects on physical and mental health, including respiratory problems, memory and cognitive issues, dependency, and other adverse outcomes. The risk of harm increases with higher and more frequent usage.
If you are concerned about the potential damage done to your health due to marijuana use, it is essential to consult with a healthcare professional or a substance abuse counselor. They can provide personalized advice and support based on your specific situation and health history. Additionally, they can help you explore healthier alternatives or strategies to reduce or quit marijuana use if that is something you wish to pursue.
