Forms: Capsule, powder, or seed-based teas
Primary Uses: Mild relaxation, sleep support, minor pain relief
Effects: Sedation, calmness, mild euphoria in high doses
Potency: Low compared to pharmaceutical opioids, but can vary
Even though they are natural, misuse or large doses can carry risks, especially if purchased from unverified sources.

In the UK, poppy seeds themselves are legal, but any concentrated extract containing opiate alkaloids may be controlled under the Misuse of Drugs Act 1971.
What This Means
Poppy seeds: Legal for sale, cooking, and consumption
Poppy capsules with alkaloid extracts: Potentially illegal if they contain detectable morphine or codeine
Importing concentrated extracts: May be treated as controlled substances
Penalties: Possession or supply of controlled alkaloid extracts can lead to criminal charges
