The line these laws draw
The Dutch, German, British and American texts follow the same split. The seed is food and falls outside the drug laws. Opium (the dried latex) and poppy straw (all parts of the plant except the seeds, after harvest) are controlled. That is why a bag of poppy seeds can be sold in a supermarket while dried poppy capsules can fall under the drug laws.
Food law covers the seed separately. In the EU, seed for consumers must stay below 20 mg/kg morphine equivalents (see EU limits).

| Germany | Excluded | Plant and parts on Annex III BtMG; growing needs a permit | BtMG Annex III |
| United Kingdom | Excluded | Opium and poppy-straw are Class A | Misuse of Drugs Act 1971, Sch. 2 |
| United States | Excluded | Opium poppy and poppy straw are Schedule II | 21 U.S.C. 802 and 812 |
| Singapore | Prohibited goods, import only after approval and a negative lab test | Not covered here | Central Narcotics Bureau |
Netherlands
The Dutch Opium Act (Opiumwet, text in force since 17 September 2026) lists on List I "opium: the coagulated latex obtained from the plant Papaver somniferum L." and "bolkaf: all parts of the plant Papaver somniferum L. after harvesting, with the exception of the seed", as well as concentrate of bolkaf. List I is the list of hard drugs. Poppy seeds are not on it and are sold as food. Dried poppy capsules are bolkaf. The text: wetten.overheid.nl.
The Opium Act does not mention the living ornamental plant separately, and we found no official guidance that settles the question for gardeners. We therefore make no statement about growing it in the Netherlands.
Germany
Annex III of the German Narcotics Act (BtMG Anlage III) lists Papaver somniferum, including the subspecies setigerum: plants and parts of plants, with the exception of the seeds. Dealing in the plant for ornamental purposes is exempt when its morphine content in dried form is no more than 0.02 percent, but that exemption explicitly does not cover cultivation.
Growing opium poppies, even a few in a private garden, therefore needs a permit from the Federal Opium Agency (Bundesopiumstelle) at the BfArM. Permits are issued for low-morphine varieties; the BfArM names the summer varieties 'Mieszko' and 'Viola' and the winter variety 'Zeno Morphex' as examples. Poppy seeds for baking are freely sold.
United Kingdom
Under Schedule 2 of the Misuse of Drugs Act 1971, opium and "poppy-straw and concentrate of poppy-straw" are Class A drugs. The Act defines poppy-straw as "all parts, except the seeds, of the opium poppy, after mowing", and the opium poppy as the plant of the species Papaver somniferum L. The seeds are excluded by that definition.
We did not find an official UK source that deals clearly with growing the plant in a garden, so we make no statement about it.
United States
The Controlled Substances Act defines the opium poppy as "the plant of the species Papaver somniferum L., except the seed thereof", and poppy straw as "all parts, except the seeds, of the opium poppy, after mowing" (21 U.S.C. 802). Both are listed in Schedule II. The Drug Enforcement Administration says that the seed is exempt but opium contamination on it is not, and the Justice Department has prosecuted sellers of unwashed seed, as reported by KFF Health News. There is no federal limit for morphine on food-grade seed (see EU limits).
Singapore
Singapore's Central Narcotics Bureau classifies poppy seeds as prohibited goods. Anyone who imports poppy seeds or food containing them, regardless of amount or purpose, must file an inward declaration with a certificate from the country of origin and have a sample tested by the Health Sciences Authority. The import is approved only if no controlled substances such as morphine are found (CNB).
Travelling with poppy seeds
Several other countries, mainly in the Gulf region and East Asia, are reported to restrict poppy seeds, including in food, but we could not confirm the rules from official sources. Before travelling with poppy seed products, check the customs authority of the destination country. Also keep in mind that a positive drug test abroad is judged under local rules.
