I seriously doubt her medical marijuana use played a very large role in her story, and I wouldn't make too much of it, or assume that it, alone, explains what happened. Even chronic marijuana abuse just isn't all that debilitating. But other medical conditions, or medications she reportedly may have run out of, may have been contributory factors.

Also, she was reportedly an "avid outdoorswoman," but just not planning on going for a hike, and she only had one crash, not two. We don't know why that happened. But hers was not the first car to end up in a ditch for no obvious reason.

She had apparently just been arrested for DUI of drugs, which can also include prescription or OTC medications other than marijuana. We just had a vehicular homicide conviction reversed that was premised on nothing more than a minuscule trace amount of prescription Xanax in the driver's blood. So it can happen unexpectedly to people being treated for legitimate medical problems, too, not just drunks and stoners. I know of DUI convictions based on OTC cold medications alone. Lots of substances have sedative effects.

Things like chronic pain syndromes, diabetes, depression, and other medical conditions, as well as the medications used to treat them, can cause sudden, unexpected, and very debilitating effects or side effects. Patients can experience confusion, blackouts, hallucinations or even psychotic episodes, especially under the added stress of a DUI arrest and possible conviction.

The DUI probably was caused by medical marijuana. Her crash and subsequent seemingly bizarre behavior probably was not. I'm guessing she either screwed up or missed her meds, was pretty stressed out by her DUI (wouldn't you be?) and maybe had an exacerbation of some medical condition, or even a half-hearted notion of suicide, and suffered a bit of mental disconnect in a setting where no help was at hand.

I'm glad she's alive, and I'm not ready to be too hard on her, at least not until we hear more of the story.
