Dramatic increase in arrest for possesion

I believe that possession of small amounts of marijuana should be decriminalized in Canada for adults.I have some concerns about large grow ops and the danger that may surround them but at the same time I don't think the current policy is working and sending people to jail for a small amount doesn't make sense.Maybe in the future it should totally be legalized and the government should tax it the same way alcohol and tobacco are taxed,that might remove some of the criminal element from its sale and production.
