You can make poppy seed tea with unwashed poppy seeds. From experience, you even used to be able to buy unwashed poppy seeds from Amazon in the UK.
It's incredibly addicting and even harder to quit than heroin, because there are many alkaloids present in the tea, all with different half-lives and strengths.
All you'd do is pour some seeds into a bottle, add some citric acid, add some strong-tasting liquid to cover the taste, then shake the whole thing, strain out the seeds and drink the result.
I'd like to add that doing this is very risky, because it can be quite hard to know how strong the tea ends up being, and so it's easy to take too much. And poppy seed tea absorbs a lot faster than you might expect too. I had friends who were "seasoned" opioid users who supposedly knew what they were doing, who OD'd and died from poppy seed tea.
