I believe you should not teach complete and blind obediance to the law. Skepticism and doubts regarding moral are what keep laws and morals evolving into better and better. And if you always obeyed the law, you would never smoke weed. In fact, you would betray all your weedy friends and bust them to the police.
Correct me if im wrong, but democracy was born due to disobediance(but the government of England sort of had promised voting rights...)...I dont know what im talking about, haha.

Anyway, i believe that with drugs you need to be very two-sided. You need to realize the comments of people who are like "weed will make you kill your mother", and on the other hand you need to realize the comments of people who are like "ive been doing cocaine daily for 20 years and im in a good shape, drug laws are bullshit!".
