A Bamse episode in which Skalman tells about an adventure in his youth where a magician offered him an extract made from red flowers. The first taste felt great and moved him to a country of previously unknown wonderful sensations, but as Skalman is a very smart person he understood what it all was about (the magician wanted to make him his dependent slave), and only pretended to drink the rest of the potion (he managed to pour it into his shell).
In spite of the message being that drugs are bad, the bit about how wonderful it felt was too much to bear for many parents who preferred to tell their kids, and perhaps believed themself, that drugs only have bad sides.
