If you decide to manufacture cyanide, you should do it with extreme care. After making the product, you should test it before using it especially if you are using it to commit suicide. This is to ensure that the product works. The results of a backfired suicide attempt can be excruciating. If you are manufacturing cyanide at home, you might think of combining sodium cyanide with concentrated hydrochloric acid to make hydrogen cyanide gas, which is very lethal in an enclosed space.

When using hydrogen cyanide gas to carry death penalties in the US, reports have shown suffering during executions. Some prisoners took more than ten minutes to die and showed agonizing pain at that time. The method was later abandoned as the standard method to execute prisoners in the US. The state of California said it was “unconstitutionally cruel.”
