Two shops selling cannabis or more specifically "cannabidiol" based products (CBD) opened in central Paris and just outside the capital. Cofyshop, the first of its kind in the French capital itself, is located in the trendy 11th arrondissement and the other, E-Klop is in Puteaux, a west Paris suburb. There has been a softening on cannabis laws in France which means that it is legal to sell a weak version of the drug. In order to be within the law, the product sold must contain less than 0.2 per cent of THC (tetrahydrocannabinol), which is the main psychoactive ingredient in cannabis. The products do however contain CBD. (See also: A closer look at France's 'legal cannabis' derivatives | Les «coffee-shops» qui ouvrent partout en France sont-ils légaux?)
