It is not terribly complicated for most people given access to the right drugs. Right to die groups in Switzerland successfully use a single large dose of a barbiturate, either injected or taken orally (in the latter case, an antiemetic is usually also given to prevent vomiting). Barbiturates are also favored, where available, for medically assisted dying in the United States. The larger problem is access to the drugs. Barbiturates are not favored for most other purposes due to the high abuse potential. I believe is why they are not recommended for this purpose in Canada, for example.
