It's a fine assumption. We could also assume that marijuana use discourages use while under the influence due to increased paranoia. Neither have been demonstrated yet.
All we know from this is that there was a increased detection of thc for people involved in fatal accidents. The reason for this seems obvious to me and I assume it correlates with general increased use among the population. I still conject that "fatal" accidents are used here to push a particular narrative. I don't see any significance in "fatal" versus cumulative accidents or DUI arrests.
If the intent is to prove that there is an increased hazard on the road due to marijuana use, then they need to prove that it's use significantly increases this hazard AND that the rate of drivers under influence has increased. Those are two separate and independent studies.

I'm still waiting to see those studies.
