Hi there, I do not smoke either. However... To play Devil's Advocate... Weed is an illegal drug here. If you get caught with it, you will go to jail. I assume you are in Mexico by your flag. Well, if you come here to visit a dojo and you happen to bring some of it, you will be bringing an illegal drug into the country that can get you deported if you choose to bring it.(Not saying you would, but I thought you should know that in case you didn't realise that.) Is weed an illegal drug there or not? If it is, then if I was you, I'd quit. I have heard jail there is really not the nicest place to be. Getting high causes you to lose your judgement, too. If you got high before class, you could hurt someone in the dojo. I think doing drugs, if you'll excuse me, is very very stupid as it kills brain cells and impairs judegment. You don't need to get high to have fun. Even though you say you only smoke it occasionally, it is still a very bad idea to smoke it. A drug is a drug no matter how you put it.
