"Autoerotic asphyxiation." Know of a case, a death, ruled accidental, by autoerotic asphyxiation. The job colors everything I think. That's what I first thought when my son sent me the photograph. Was unaware, totally unaware, of that mechanism to smoke weed. Legal speciality is homicide, not weed. Didn't know that you could buy gas masks to smoke weed on Amazon. No idea. Don't know why a college, soon to be professional, tackle football player would self-shoot smoking weed via gas mask and post it on his twitter account. No idea.
