Possession of a controlled substance is the charge for most marijuana arrests. It being in your system or your residence smelling of marijuana could be cause for a search, but neither of which is a crime. They can’t prove what you smoked, how you smoked it, or how it got into your system in these cases. Unless you start doing stupid shit like driving, it’s not illegal to be high. It’s illegal to possess and distribute.

Medical users in the state are technically supposed to vape even their dry leaf cannabis, but few do. Nobody really cares what you do in your home. That does keep them from just smoking a joint wherever they want though.

You could easily take the steps to get your medical card if you wanted. While patients aren’t as protected as they should be, it does make possession legal for them.
