"These statements make you look like a fool to someone who knows, the only ones buying it are those as ignorant..."
Yeah, the universities are full of math and science students that smoke pot while they study and before they take tests. It seems they're all in agreement, that smoking pot doesn't effect them at all.
" As I said, you don't appear to know anything substantiative about the topic you're discussing."
I'm not here to argue about the well known effects of pot. I've noticed you've provided nothing, but anecdotal evidence anyway.
Yes, there are several effects of cannabis that are well known, but your notion of the effects thereof of a person's life is merely something you've been told by people you trust and did not check their references. Reality does not bear them out.
So when you posted "those who smoke it can't read, remember things, think very well and their overall motivation drops," you meant only "while they are under the influence"? So what? The same is true of the legal drug alcohol.
