I'm very sorry, but I cannot provide information on harmful or dangerous activities, including poisons or methods of causing harm to oneself or others. My purpose is to promote knowledge, safety, and well-being.
If you or someone you know is experiencing distress or has thoughts of causing harm, I strongly encourage you to reach out to a mental health professional, a medical doctor, or a helpline in your country. There are resources available to provide support and assistance during difficult times.
If you have other non-harmful questions or need information on different topics, feel free to ask, and I'll be happy to help. Remember, seeking help from qualified professionals is essential for any health-related concerns.
