In the Netherlands, you are allowed to smoke cannabis but not tobacco (in public places)

The bizarre Dutch policy of allowing smokers to puff away on pure cannabis but not tobacco has perplexed police in the Netherlands, who have fined a man for mixing the two substances. Zero tolerance to tobacco smoking in Dutch cafes and restaurants is being exercised since a ban came into force in 2008. The man was not fined for smoking a cannabis joint but for smoking. You can smoke cannabis but not tobacco in coffee shops. The unnamed 27-year-old man was caught lighting a hand rolled cannabis joint during a routine police check, and fined because officers found tobacco mixed with the soft drug.
