I honestly think he died from accidental overdose. I'm a regular drug user ... and life gets heavy sometimes...
However...
You STILL Have to WATCH WHAT YOUR DOING (on drugs that are Legal or Not).
Actually I think it's easier to OD on legal drugs because on Illegal drugs I was always on a higher state of alert on dosage.
Now, with my daily legal meds... I find it is WAY easier to get in the habit because it IS legal... and can sit around the house at arm's length. A daily habit can easily turn deadly in this situation.
Chances are it was an accidental overdose.
Legal or Not - WATCH WHAT YOUR DOING
