Tienda de semillas de marihuana.

Amazingly there are marijuana seed shops here.
Spanish law entitles one to grow enough cannabis “for personal consumption.” However, there is a grey area here because the law does not state exactly how much this is when the cannabis has not been harvested. Most people tend to agree that the maximum amount allowed is three to five plants per person. However, this is urban legend; there is nothing in Spanish law that stipulates an exact number.
The ambiguity of cannabis laws in Spain has led to a uniquely Spanish innovation: the cannabis club. These exploit the fact that cannabis is allowed to be consumed on private property and that one can grow cannabis for others, as long as it isn’t sold commercially.
