Yeah it is likely that this is due to pressure from the US. Our lame gov tries to pull shit like this with Canada all the time. Did someone say Marc Emery?
Oh wait I did.

Well dont be suprised when the the same type of thing goes down state side. I imagine the DEA would love nothing more than to have cannabis reclassified to its own category, Schedule 0 maybe.

I find it pretty funny and also pretty sad that they decided to reclassify when the data shows that whatever drug control policy is in place seems to be working. I guess this is always the behavior of the drug war terrorists: If a harsh policy is working it's best to make it harsher.
