I predict this thread will soon be become:
"We're better than you because we do not smoke weed"
vs.
"Weed shouldn't really even be considered a drug, and here is my statistical proof"
So., I'll help it along the way.
Considering I'm an irresponsible weed head, I truly believe this conversation boils down to acceptance of what society or government tells us is Ok or acceptable. I think the alcohol prohibition comparison is an extremely fair comparison in favor of the 'weed heads', especially considering that alcohol is a substance far more likely to cause people to act irresponsibly than marijuana. Also, for the most part, synthetic medicines that we are so quick to pop into our system seem to be frequently proven to be far more dangerous to our health.
The country is coming around and eventually we'll hear terms like 'weed heads' and many of the stigmas that are associated with marijuana will go away. Just like when the gubment told us alcohol was Ok.
I've yet to hear an argument on why marijuana should be illegal that could not also be applied to alcohol and / or tobacco. However, I think very strong arguments could be made as to why either of those substances are better candidates for prohibition than marijuana.... add to that a handful of pharmaceuticals.
