Fabric is - as you know - not made out of a continuous material but rather fibres. These fibers allow for movement up to the point were the network is in tension. This tension is the result of bonds. While the fibre itself relies on covalent bonds of extreme strength the bonds between different fibres are way way weaker. So weak that they “feel” temperature. Also a polar solvent like water weakens these bonds significantly. If you iron fabric while it is laying flat, the fibres rearrange to minimise tension. The new arrangement hardens out while cooling. The new arrangement prefers a flat structure. That way it looks flat on your body.

Two reasons:

1. There are long term plans to legalize it. Currently it may be against International Law so it will take a while until it can be opened for all. The first action will be scientific observed modell citys.
2. The decriminalisation will aim to destroy the black market. This is done by allowing social clubs than can grow their own plants and hand their members up to 50 Gramms. That is a lot and the implicite idea is that this amount will also allow a bit of interchange without being enough to drive a illegal business.
