Question
Does smoking weed [i.e. marijuana] make me a sinner?
Answer
One of the commandments in the Torah is that we have a responsibility to keep our body healthy, and maintain our ability to do the right things. Since “weed” damages various parts of our body, and impedes our ability to choose right from wrong, it should not be used.
