Smoking ban in Netherlands

This july the Netherlands joined the growing number of countries, that ban smoking in restaurants and cafes also including coffee shops. There most important reason behind this new law, is that all employees have the right to a smoke-free workspace. But in the Netherlands there is one significant difference to the law than in the other countries. You can still smoke, but only marijuana. And only on it´s own. It is illegal to mix tobacco with marijuana. The Netherlands is well known for it´s liberal views and laws. So it may come as a surprise that they have a smoking ban, but still allow marijuana. I find this strange. Why not ban both? Why allow the strongest of the two? 

At least people can now go out and not breath secondhand smoke. Laws like this have helped bring down the amount people smoke, and number of smokers. People that cannot be around smoke can now enjoy life much better. At the same time I understand that the owners are not in favor of the new ban. Business is not going as well since the law came into place. My words to them are hang in there, it will take some time but people will be back. This is what happened in the other countries. 

Ireland (2004) was the first country to ban smoking in all enclosed workspaces. Norway (2004) followed not long after. New Zealand (2004) was the third country. The United Kingdom (2006) came  with a similar ban a few years later. Denmark (2007) passed a law the nest year. France (2008), followed the next year. Along with Sweden (2008), The Netherlands (2008), and Romania (2008). Some US states ban smoking in the workspace. Bhutan banned all sale and smoking of tobacco back in 2005. And they are the only country yet to do so.
