All methods have plusses and minuses- we should not push people in a certain direction, only support them and their right to make whatever choice works best for them. One good place to start seeing what is practical to work is to search on the internet by "lethality of suicide methods" and then consider the risks of what if it doesn't work. For example firearms have the highest lethality, some say 80%, but they also have the highest risk of very bad outcomes if it doesn't work- many people blow off most of their faces and survive- a lot of these people have posted on youtube- you can see thier videos, they are terrifying. For me the downside risks are way too high with this method. So you would need some time to research methods and decide, which is no great comfort to someone who wants to end their pain asap. In the U.S. anout 1 in 30 suicide attempts works, so this research is important- a high percentage of failed attempts come from attempted drug overdoses or by cutting, both of which work less than 2% of the time and often end in involuntary hospitalizations, which most people really dislike a lot. Research is the key- each person needs to make their own choices.
