Notes:

The legal status of Codeine:

Codeine is a less addictive Schedule II and Schedule III drug under the United Nations Single Convention on Narcotic Drugs of 1961 and is strictly regulated worldwide. For instance, in Australia, Canada, New Zealand, Sweden, the United Kingdom, the United States, and many countries, Codeine is regulated. However, many countries or regions allow people to buy certain codeine-containing medicines without a doctor's prescription, such as cough syrup.

The codeine content of those medicines is low, and the quantity of each sale is usually

limited. Because these drugs can easily extract high concentrations of Codeine from them and become one of the raw materials for processing into addictive medicines, many countries still prohibit people from bringing such drugs into the country, such as Thailand.
