I don't really care if it is illegal or legal. I also avoid normal smokers and drunks. Also i truly doubt marijuana will ever get legal in Denmark. Also if you are smoking weed, I see no reason why I should find out over the internet. The only way I should is by you being oblivious or by you being so damn stoned that it is apparent. Some of the people I play with in-game may be smoking weed, but if I don't know, they must be doing it in moderation.
Also, if something is given by prescription we know that it has been tested and that it is made sure what exactly it does to your body. And if you are given medicine, only take as much as you have been told, never self-dose how much you think you need. If you feel that you need more, contact your doctor. There is most likely a reason why you were told not to take it as much as you feel like.
