the bible doesn't speak clearly on the issue. there are scriptures to support both arguments, so it is PURELY left up to interpretation like most things.

funny thing is that even if it was spoken clearly about, it could most likely be argued by claiming it was a "cultural commandment" like not eating pork and not cutting your sideburns. the bible says for men and women to sit on different sides of the church and for women not to speak in church... how many churches in america obey those commands?

one could always battle with the "translation" argument... key issues like the "doctrine of the trinity" have caused massive division and opposing sides are both "positive that their translation is more accurate". so many factors all point to personal opinion and interpretation, the very cause of hundreds of divisions in christianianity.

if jesus thought marijuana use was an important issue he would have spoken clearly about it like he did regarding MAJOR ISSUES like loving your neighbor and caring for the sick, poor, widowed, and orphaned. weed was in use long before jesus' time but he did not address it.

The greatest scripture to me...
Roman 13:8 - Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law.

That sums up spiritual truth in my opinion. I do not believe jesus was divine but i do admire the core of his teachings and think he was an enlightened human. It confounds me though that people who claim to follow "jesus christ's teachings" put as much time and effort into fighting issues like gay rights and others when there is an "endless sea" of poor and broken to be cared for that he directed to make priority.
