This nonprofit centre offers visitors tips and tricks for having a positive smoking experience, as well as provides the lowdown on local cannabis laws. Browse displays, try out a vaporiser (€3; bring your own smoking material) or view marijuana plants growing sky-high in the basement garden (€3; photos permitted).
Staff can provide maps and advice on where to find coffeeshops that sell organic weed and shops that are good for newbies. T-shirts, stickers, postcards and a few other trinkets with the logo are for sale, too.
