Yes, I think that eventually cannabis will be decriminalized pretty much everywhere. Don't hold your breath though, it'll take a while.
If it's any help, cannabis is illegal in Tx and I "chong doobs" all the time. Except I usually smoke through a pipe these days. Same principle, prohibition doesn't do much to the flow of drugs. I think that it's fine to smoke weed regardless of the law, but there are risks involved. To me, it's worth it.
